PART – A 1.0 GEOLOGY AND EXPLORATION
(a) Briefly describe the topography, drainage pattern, vegetation, climate and rainfall data of the area applied/mining lease area.
Topography & Drainage Pattern:The area has generally flat to gently undulating topography. There are limestone cliffs along the sea coast near Jafarabad and Babarkot villages. There is large mud flat forming marshy land connected by Jafarabad creek. The highest contour at 48m runs in south eastern area and lowest contour of 30m runs in southern part of the applied area. The applied area and even the surroundings are exposed as comparatively sub undulating terrain of limestone dominated by the milliolitic limestone. The applied area is surrounded by two working and captives mines of UltraTech Cement Ltd, The Narmada Cement-Jafrabad Works & Gujarat Cement works.. The surrounding mining leases are under active working feeding to its two clinkerisation units. The applied area is lying in between these mining leases and geologically no changes observed. There are three old pits viz OP-1, OP-2 & OP-3 near boundary pillar no. 14, 33 & 55 respectively which are covered by windblown sand. There is neither any perennial nor seasonal drainage system existing within the applied area. In the area drainage is developed by Raidi river which is ephermal in nature and roughly flowing north to south at a distance of 8 Kms in a NE direction from the area and eventually merges into Jafarabad creek. General slope towards south & west direction and rainwater flows along slope. Climate & Rainfall: The climate of the area is characterized by general dryness (except during the south-west monsoon season) and hot summer. The temperature ranges from 9.4oC to 42.2oC. The rainy season extends from mid June to mid September. The mean annual rainfall has been recorded as 819 mm. The relative humidity is generally high during the period from June to September and is least during the January-February period. The predominant wind direction from May to September is from West and South West while in the post monsoon and winter it is from SW to NE. In April to June the sky remains cloudless and moderately clouded during July to September. Vegetation: The applied ML area is not having any indications of good vegetation. The applied ML area is generally devoid of large trees which includes very poor vegetal cover, Acacia Nilotica Acacia ninuata, Prosopis juliflora are some of the common species. Besides common trees, natural vegetation grows mostly during monsoon and fades away with the onset of summer. The area does not have any rare and endangered species.
(b) Brief descriptions of Regional Geology with reference to location of lease/ applied area.
Regional Geology of the Area The Deccan-Trap-covered coastal region of Saurashtra had experienced a number of marine transgressions and regressions during the late Tertiary Period. The rich limestone beds of the region were deposited by the accumulation of calcium-rich forameniferal (Miliolitic) crust and chemical precipitation of carbonates from the shallow sea. Land-derived material from volcanic constituted the impurities in the limestone deposit. The regional geological set up of the Coastal Saurashtra Region is given in Table: A1.1.

Table A1.1: Regional Stratigraphic Sequence of Rocks Age Formation Lithology
Holocene Recent Wind-blown sand, Fluviao-marine deposits.
Sub-recent to Pleistocene Porbandar Beds Miliolitic limestone, Marl, Calcareous shale, etc.
Pleistocene to Pliocene Dwarka Beds Cherty limestone, Clay, Silt. Pliocene to Miocene Gaj Beds Variegated clay, Marl, Impure
limestone, etc. Eocene Supratrappean Impure limestone, Calcareous
sandstone, Lateritic rock. Eocene to Cretaceous Deccan Trap and
Intertrappean Basaltic rock, with minor
Intertrappean clay. Traps: Deccan Traps occupy most of the area. They include several types of volcanic rocks, which have come up through fissures in several eruptive phases. The main rock types encountered are intermediate types of basalt, trachyte, diorite, rhyolite, etc. The hilltops generally contain the hard and tough, compact massive flows, whereas the soft type occupies the valley floors and the plains. The hard flows stand out, whereas the softer ones are weathered to form low areas. The entire trap rocks show shearing and multi-directional fracturing. Gaj Beds: Gaj beds occur as isolated outcrops at the margin of traps towards coast and as small mounds in the alluvium. They are marine sediments, comprising fossiliferrous yellow marly limestone with clay. Miliolite Limestone: The limestone deposits of the area are termed as “Coastal deposits”. It is marine limestone commonly known as Miliolite Limestone which occurs as thick cross-laminated beds. The name “miliolite” has apparently been derived from the Miliolidae, belonging to the common foraminifera present in the rock. Occurrence of such distinctive type of rocks is reported only along the Saurashtra (Kathiawar) coast and Kutch in Gujarat. Recent Deposits: The youngest deposits in the district are represented by various types of soils, alluvium, windblown sand, fluvio-marine mud deposits of tidal flats and shell and shingle deposits of shore area.
(c) Detailed description of geology of the lease area such as shape and size of the mineral/ ore deposit, disposition various litho-units indicating structural features if any etc. (Applicable for Mining Plan for grant & renewal and not for Scheme of mining/ Modifications in the approved mining plan/scheme of Mining)
Stratigraphic sequence of the applied ML area is as under: 1. Wind Blown Sand 2. Miliolitic limestone intermixed with Marl construe 3. Deccan traps (basalt)
Windblown Sand The younger most geological formation in the ML is windblown sand constitutes the overburden with an average thickness varying from 0.5m to 4.0m. Occupying the flatter grounds, the thickness of overburden is comparatively more towards Kovaya and Vandh village while the thickness decreases towards village Babarkot which is on higher ground.
14
Miliolitic limestone Just below the windblown sand, miliolitic limestone occurs as compact limestone & marl of varying thickness which can be average out to 25m. With depth, there is general deterioration in the quality of limestone accompanied by soft, friable layers & lenses of marl. The limestone is buff, yellow or pinkish in colour, while the weathered surfaces show sooty to brownish appearance. The main constituent of the limestone is the calcic shell fragments of Miliola and related organisms. The limestone deposit shows enrichment in calcium content at the upper layers, due probably to leaching out of silica, calcium enrichment by capillary action and re-deposition in crevices. The limestone is generally compact, hard and bouldery in nature at many places. The average quality of limestone is varies in terms of CaO 40.0 to 48.00, SiO2 4.0 to 7.5, Al2O3 1.5 to 3.0 and Fe2O3 1.0 to 2.5. Deccan trap (basalt) Below the limestone, Deccan Traps occupy most of the area. It includes several types or volcanic rocks, which have come up through fissures in several eruptive phases. The main rock types encountered are intermediate types of basalt, trachyte, diorite, rhyolite, etc. The entire trap rocks show shearing and multi-directional fracturing. Structural Features The limestone of this area is miliolitic limestone, which follows general strike N700E- S700W and dips gently in NNW-SSE direction. Minor vertical and inclined joints are present and can be observed all along the mine face.
(d) The Directorate of Geology & Mining, Govt. of Gujarat has explored the area so far as detailed in Table A1.2 below. Besides this, the area has also been explored in the adjoining mining leases (Narmada Cement Mine of Ultratech Cement Ltd.) of the same company in the year 1975-78.

Entire mineralized area may be analyzed meter wise with 10% of check samples. (At least for 10% of total samples may be analyzed in accordance to BIS and reports from NABL accredited/ other government laboratory). Sample analysis attached from NABL accredited Lab.
The quality of limestone exhibits distinct lateral as well as depth variation. The limestone is mostly of cement grade i.e. below 43.82% CaO. Further the lower level deposit is mostly of inferior limestone/ marl having presence of free silica as compared to the upper level limestone. Deposit Quality The average quality of the entire deposit has been estimated and is summarized below: - ROM Quality of Limestone Since there is little overburden in the form of windblown sand and also not any remarkable intercalations observed within the limestone (as can be seen in the borehole logs and pit face of nearby mining leases) the Run of Mine (RoM) quality of limestone can be considered to be the same as the overall average quality of limestone as estimated for

Submit a feasibility/ pre-feasibility study report along with financial analysis for economic viability of the deposit as specified under the UNFC field guidelines may be incorporated.
Assessment of the deposit has been carried out based on the followings: - 1. Core bore hole data of nearby operative mining leases, bore holes comprising of
topographical data, assay data etc. 2. Old pits available in the area 3. Exposures of mineral in the area 4. Prospecting work carried out by the state govt.
19
Estimation of Resources/ Reserves Method adopted for Resources/ Reserves estimation Estimation of resources and reserves has been carried out by cross sectional area method. i) Area and Depth Considered for Resources/ Reserves estimation For estimation of geological resources, the depth considered is based on as encountered in bore hole drilled. ii) Usable Limestone The entire limestone have been considered as usable limestone for manufacture of quality Ordinary Portland Cement (OPC). Thus the cut off limit has been set below as prescribed by CCOM Circular No. 03/2010 dated 14.07.2010 (>34% CaO and <4% of MgO) during estimation of limestone resources/reserves. iii) Ultimate Pit Limit in the Mining Area The ultimate pit limit has been marked on the basis of the extent of mineralization observed within the area of ML. Laterally the boundary barrier within the lease area forms the limit of mining while at depth the ultimate pit limit shall be restricted upto 0 mRL levels. iv) Tonnage Factor An overall tonnage factor of 1.8 has been considered for limestone for this area as the same has been taken for estimation of resources and reserves in the nearby working mines. (Annexure-IX) Resources/ Reserves Categories The resources and reserves of the area has been categorized under different geological axis as per the followings: - 1. Inferred resources (G3 Axis): The first estimate of grade and amount of limestone in a deposit calculated purely based on data available and supplemented by surface exploration. Such an estimate is based on assumed surface continuity and width of the bed on geological evidences, which included information from past nearby mining activity and comparison with similar deposit in the locality. In this case, the reserves which fall outside 100 m zone on either sides of the G2 axis are classified as G3 axis. The area under this category is measured as 30.0454ha. 2. Indicated resources (G2 Axis): This category of resources estimation carried out partly from actual exploration in the nearby area and on geological grounds. The grade and tonnage of the ore blocks shall be calculated on geological grounds based on widely spaced drill holes carried out by state govt. and pits. In this case, the resources/ reserves which are falling between 100 m to 150 m on either sides of the bore holes and upto 00 m above MSL has been classified as Inferred. The area under this category is measured as 7.20ha. 3. Measured resources (G1 Axis): The resources/ reserves estimated by details proving by sinking drill holes by state govt., exposures, old pits and nearby boreholes by the same company has been placed the deposit in this category. In this case, the resources which are falling within the command length of 100 m on either sides of the bore holes, old pits and upto depth of the bore holes has been classified as measured category of resources. The area under this category is measured as 12.60ha. Basis for awarding UNFC code 1) All the reserves falling under G1 axis are placed in the mineable proved i.e. E1, F1
& G1 category (111) based on the availability of mineral in the area and as the
20
reserves are falling in the private land and the land is owned by the applicant. This reserve is devoid of mineral resources blocked due to safety barrier, working
to be restricted upto 0 mRL, narrow spaces etc. 2) All the reserves under G2 axis are placed in the category mineable probable i.e.
E1, F2 & G2 category (122) of reserves based on the information available in the area and as the reserves falling in the private land which is owned by the company and pre feasibility study carried out for the said area.
3) The resources under G1 & G2 axis which cannot be mined at present due to working below 0mRL, making safety bench, along statutory boundary barrier etc. are placed under Feasibility Mineral Resources and are classified under code 211 & 222.
4) The resources under the Inferred G3 axis are resources category outside the indicated mineral resources upto applied area boundary is placed under 333.
Pre Feasibility Study Report is enclosed as Annexure-XI. k) Furnish detailed calculation of reserves/ resources section wise (When the mine is
fully mechanized and deposit is of complex nature with variation of size, shape of mineralized zones, grade due to intrusion within ore zone etc, an attempt may be made to estimate reserves/ resources by slice plan method). In case of deposits where underground mining is proposed, reserve/resources may be estimated by level plan method, as applicable, as per the proposed mining parameters.
The resources/ reserves estimation has been carried out by cross-sectional area method. In the estimation, the formation was identified viz. limestone. The cross-sectional area of litho unit is computed by graphic method on each cross section. The average intersectional area is calculated by averaging the cross-sectional areas on two consecutive sections. The average cross sectional area is multiplied by mean distance between two consecutive sections to arrive at the volume. The volumes so determined were converted to weight (in-situ reserves) in tonnes by applying density/ tonnage conversion factor. Finally the mineable reserves have been estimated by depletion of blocked resources. The thickness of mineral varies from place to place; using the influence of boreholes, the average thickness of the mineral bed is 30 m. The deposit is sedimentary origin. The lease area does not contain any structural disturbances. Total 5 (A-A’, B-B’, C-C’, D-D’ & E-E’) cross sections have been drawn across the entire applied lease covering G1, G2 & G3 axis. A distance of 200m has been kept each between two consecutive sections.

2.0 MINING
2.1 A. OPEN CAST MINING: - a) Briefly describe the existing as well as proposed method for excavation with all
design parameters indicating on plans/ sections: - Salient description of proposed mining method
Mining operations is proposed to be carried out by opencast fully mechanized method of mining by making benches of height 6 m (normally 6m) with width 15m and maintaining working bench slope of 750. Conventional method i.e. drilling and blasting is proposed. Surface Miner is also proposed for winning of mineral in case of additional option. Looking towards heterogeneity of deposit, separate mining of limestone is just impossible. Hence entire ROM material is proposed to be feed to crusher directly. The blasting zone would be fixed away from local vicinity in the lease area or may be selected in the running development block with suitable measures. The mineral being free from overburden (except sand) therefore there is no need for any mine development work during mining operation except removal of sand. The excavation, loading and transportation is proposed to be carried out by hydraulic excavator, loader, dumpers and tippers. Drilling is proposed to be done by ICM 260 drill machine with blast hole burden 4.0 m and spacing 5.0m. ANFO is proposed to be used with slurry explosive. Blasting frequency shall be 2 to 3 a week. Safe and controlled basting shall be practised by competent authority as the same is being in practice in nearby working mines of the same unit. Excavator of capacity 4.0 cum shall be used for loading of fragmented rock mass of mineral and transported to crusher situated outside the ML through dumpers and tippers. The details of the installed crusher is: - Type of crusher - Impact Crusher Capacity – 500 tonnes/hr Hourly output- 450 tonnes Output per day 8100 tonnes Besides conventional method, surface miner is proposed in a specific situation which is eco-friendly especially in blocks near habitation and boundary areas. The salient features of surface miner are safe and steady operation, minimum dust generation and low noise. It strips the strata in slices of 25-30 cm thickness and 2-2.2 m width. The Broad parameters of mining operation will be as below:
Number of working days : 300 days/year Working shift/day : 1 shift of 8 hours Working benches : 4 Height : 6.0 +/– 2.0 m Width : For running bench 15 m (min.) for closing bench 4.5 m Bench slope : 750 Ultimate Pit slope : 450
There are old pits (OP-1 to OP-3) present in the mine with maximum level upto 35.8 mRL. The grid reference of extent of all the old pits is from 432N-460N/72E-118E, 721N-745N / 212W-241W and 702N-721N / 343W-356W respectively.

Refer Surface Plan, Plate No. 3 on scale 1000:1.
b) Indicate year-wise tentative Excavation in Cubic Meters indicating development, ROM, pit wise as in table below.
Opencast method of mining will be practised with fully mechanized means by drilling and blasting. Occasionally surface miner is proposed to be deploy as an second option. Overburden (sand) removal is envisaged from the Babarkot Limestone Area. Total mineable reserves quality stands at 43.8% CaO. To meet the plant quality requirement the ROM supply is optimized at 97 LSF. Thus lower grade mineral from area will be utilized which will eventually lead to mineral conservation. It is proposed to produce 2.5 lac TPA of limestone from the area and remaining from the existing mine and one another applied in the vicinity. ROM quantity comprise of limestone. The production target shall be proposed in line with Consent to Operate. Accordingly development blocks are being proposed. The stripping ratio of limestone to overburden for the first five years of mining operations will be 1:0.05. Details of bench-wise year-wise development and production for the first five years has been given in table below.

Conversion factor has been taken 1.8 for conversion of volume to tonnage for the purpose of mining of mineral. The development location may change at few locations due to following reasons: - 1) Land acquisition problem. 2) Depending on rainfall, surface water storage/ conservation of water in last bench. 3) Although mine planning has been proposed one location looking towards required quantity, quality and also in the conservation of mineral. A total of fresh area is also proposed under mine planning in view of the advancement of pits. Company is looking forward to have more surface rights which is a continuous process in mining industries. In view of possession of new area and also in quality matter, slight changes may taken place in proposed mine planning & development upto 10-20%.

Year wise working plan and sections showing pit layout, stacks of sand, plantation location etc. is enclosed as Plate No. 5A to 5E & 5S. d) Describe briefly giving salient features of the proposed method of working
indicating Category of mine. sr Items Details i) Method of mining
With bench parameters It is proposed ‘A’ category mine to be worked by opencast method of mining with mechanization maintaining bench height of 6+/- 2.0m and sloping bench at about 75 degree and bench width >15m. The bench nomenclature i.e. OB sand bench is assigned as first bench of average thickness of 0.5m to 4.0m. The mine working is proposed to be worked in 1 shift of 8 hr. The average distance from proposed working pit to crusher is 3km. The quality of limestone from this area is not self sufficient to prepare required raw mix for clinkerization hence blending with lower CaO limestone is required before milling along with other ingredients.
ii) Drilling DTH drilling by 110 mm DTH drills using Atlas copco-ICM-260. The drilling is proposed keeping burden 2.75m to 4.0m and spacing 3.75m to 5.0 m.
iii) Blasting Shock tubes & detonating fuse along with electric detonators are proposed to be used for initiating the explosives. Shock tube is proposed commonly to be used to keep ground vibration and AOP in control. Charging and firing patterns shall be proposed by skilled blasting engineer and verified by blasting manager. Utmost care shall be taken to minimise AOP and ground
30
vibration while designing blast and it’s firing & charging pattern. Ground vibration and AOP is proposed to be measured by Nomis Mini Supergraph instrument for each blast. Average powder factor envisaged to 10 te/kg as being practised in nearby mines.
iv) Excavation The geological investigations suggest that the deposit is hard to semi hard.So opencast mechanized mining by forming systematic benches of 6.0+/- 2.0m height with proper width of about more than 15.0 m by conventional means is proposed.
v) Loading Loading by excavator and wheel loader. vi) Transportation ROM transportation shall be practised by
means of dumpers/tippers to the crusher located just outside the applied area.
vii)
Crushing/ screening Crushing unit has been provided outside the area.
e) Describe briefly the layout of mine workings, pit road layout, the layout of faces and sites for disposal of overburden/waste along with ground preparation prior to disposal of waste, reject etc. A reference to the plans and sections may be given. UPL or ultimate size of the pit is to be shown for identification of the suitable dumping site.
As stated in table above, production rate of 2.5 lac TPA of limestone is proposed during the first five years (refer Plate No. 5A to 5E & 5S). The proposed production has been tabulated in the table above. Four benches are proposed to be worked including first bench of overburden sand ir-respective of its thickness as it is practiced in nearby mine. The details of proposed year wise working is given below: - Development & production programme for 1st Year During this year the development will be carried out starting from the old pits in earlier formed limestone at locations between the grid lines N323 to 571N and 19E to 195E. Overburden soil removal shall be carried out from the first bench. During this year of mining operation total quantity of overburden soil to be removed is estimated around 22489 cum. This will be stacked temporarily at earmarked sites for OB During working it is also proposed to make ramps to access the various benches with proper gradient. Year wise tentative excavation for this year is shown in Proposed Yearwise Working Plan, Plate No. 5A. The proposed R.O.M. quantity & quality is tabulated in Table A2.5. Development & production programme for 2nd Year During this year the development in bench will move forward between the grid lines N 571N to 611N and E 195 to 277E. Overburden soil removal shall be carried out in separately at first bench . During this year of mining operation total quantity of overburden soil to be removed is estimated around 19110 cum. This will be stacked temporarily at earmarked sites for OB During working it is also proposed to make ramps to access the various benches with proper gradient.

Year wise tentative excavation for this year is shown in Proposed Yearwise Working Plan, Plate No. 5B. The proposed R.O.M. quantity & quality is tabulated in Table A2.6. Development & production programme for 3rd Year During this year the development will be carried out in earlier formed limestone benches between the grid lines N361 to 482 and E 63 to 275E. Development & production programme for 4th Year During this year the development will be carried out in earlier formed limestone benches between the grid lines N197 to 392N and 18E 277E. Overburden soil removal shall be carried out in separate bench as bench first. During this year of mining operation total quantity of overburden soil to be removed is estimated around 25220 cum. This will be stacked temporarily at earmarked sites for OB During working it is also proposed to make ramps to access the various benches with proper gradient. Development & production programme for 5th Year During this year the development will be carried out in earlier formed limestone benches between the grid lines N 197 to 456 N and E 79 to 212E. Overburden soil removal shall be carried out in separate bench as bench first. During working it is also proposed to make ramps to access the various benches with proper gradient.
ix) Extent of mechanization- Describe briefly with calculation for adequacy and type of machinery and equipment proposed to be used in different activities of drilling, material handling in development and stope, hauling, hoisting to surface, surface transportation and any other operation.
Capacities Required The designed rated capacity for limestone production during the first five years when operating at full rated capacity and with no overburden is as given below: - Mineral per annum: 2.5 lac tonnes OB sand to be removed: 0.67 lac cubic meter Waste handling Nil No. of operating days per annum: 300 No. of operating shifts per day: 1 No. of scheduled hours shift: 8 Actual utilization hours: 6
Table A2.10: Day, shift and hour wise proposed production Production In tonnes
Per day 700 Per Shift 700 Per Hour 117
The quantum and type of mining equipment proposed to be provided for various mining operations is as given below: - List of machinery proposed Drill Machines:- In order to calculate the number of drill machines required, it is essential to know the drilling capacity/ rate of drilling of one machine and the total drilling required taking into consideration burden, spacing, sub-grade drilling etc. It is
32
proposed to deploy compressed air operated down the hole Atlas-ICM 260 of 110 mm dia. holes. Drilling capacity of drill machine: Based on the performance of drill machine at Narmada Cement Mine, Atlas ICM-260 is able to drill about 20 meters/ hour. For the purpose of calculations same drilling rate has been assumed. Therefore, taking into consideration 8.0 hours a shift, 300 working days in year & 70% utilization & 85% as availability, the annual drilling capacity of one drill machine works out as follows: - 20 * 8 * 300 * 0.70 * 0.85 * 1 = 28560 say 28600 meters/ drill/ year Drilling Pattern: With 110 mm dia. drill holes, the present practice in the nearby mine is to keep burden of average 4.5m & spacing of average 3.25 m. However, for the purpose of calculating the total drilling required the above drilling pattern is being assumed. Drilling Specification for ICM-260 working in limestone works out to 4.50 x 3.25 x 1.8 =26.32 tonnes or say 26 tonnes/meter of drilling. Therefore, the total drilling required for mining 2.5 lakh tonnes per annum works out to be 9498.48 m say 9500 m. Taking into consideration 5% drilling required towards collapse of holes, misfires, abandoning of holes ect. total drilling required will be about 10000 m. No. of Blasting Drills required: Taking into consideration the drilling capacity of one drill machine and the total drilling required, the number of drill machines required works out to: 10000/57000 = 0.18 say 1.0 drill machine Assuming 85% as the availability, the number of drill machine required works out to 1 ICM-260 drills. Secondary drilling: No secondary drilling is proposed. Explosives: In medium hard rock like limestone, shale etc. ANFO along with some other high explosive as the booster/ base charge is most suitable. It is therefore proposed to use ANFO as the primary column charge and some cap sensitive high explosive like Aqua-dyne/ Super dyne etc. as the booster/ base charge for blasting. However, during the rainy season or in water holes it is proposed to use slurry or emulsion explosives. It has been estimated that consumption of ANFO & other high explosives shall be in the ratio of 80:20. In order to calculate the explosive consumption per day, powder factor of 10 tonnes/ kg for limestone. Therefore, the monthly requirement of explosive will be:
10000/ 10 = 1000 Kg. The breaking of big size boulders generating due to blasting is proposed to be done by breaker attached to L & T Backhoe wheel loader. Taking into consideration the feed size of the crusher the maximum size of the boulder which it can handle works out to 600 mm size. Explosive Magazine: As calculated above about 1000 kg of explosive will be required for blasting per month. The unit already has one explosive magazine within nearby lease area where no mining activity will be undertaken. The total capacity of storing 20,000 kg of category 2 explosive, 44,000 detonators & 40,000 m of detonating fuse. As this storage capacity is considered adequate to meet the requirement therefore, no additional explosive magazine is proposed for this applied ML. Loading of Limestone from Face: As indicated earlier, it is proposed to use hydraulic excavator of 3.8 cum. Bucket capacity & loader of 3.7 cum bucket capacity for loading of blasted/cutting material & O/B sand removal from the mine face. The production from the mine can be maintained during the first five years by working one day shift. Loading Capacity of Excavators & Loader: The loading capacity of Excavator & Loader are given by the following equation:
33
L = B x r x n x t x E/K Where L = Loading capacity per shift in cum B = Bucket capacity in cum (3.7 cum) r = Co-efficient of filling (assumed 0.8) n = Avg. number of lading cycles/hr. (taken as 90 on the basis of cycle time of 30 seconds) t = No. of effective working hours in a shift (taken as 6.0) E = Efficiency of utilization (assumed as 0.70) K = Swell factor (taken as 1.33 i.e. 33%) For Loader : a) For O/B Sand:
L = 1.6 x 0.8 x 90 x 6 x 0.70/ 1.33 = 363.79 cum /shift (say 364 cum) b) For Surface miners: L = 5.70 x 0.8 x 90 x 6 x 0.70 / 1.33 = 1296.00 cum /shift (say 1296 cum.)
For Excavator: L = 3.70 x 0.8 x 90 x 6 x 0.70 / 1.33 = 864.00 cum /shift (say 864 cum.) The handling capacity of Loader with 1.60 cum bucket capacity works out to 364 cum/ shift for sand. Taking an average density of 1.80 for limestone, loader with 5.70 bucket capacity works out to 2332.8 (say 2333 tonnes) per shift & excavator with 3.80 bucket capacity works out to 1555.2 (say 1555 tones) per shift. Number of Excavators Required: One loader & one excavator are sufficient for the proposed production capacity. Transport of Limestone in the Mine: As mentioned earlier the limestone from the face will be loaded by the hydraulic excavator & loader in to 20 tonnes tippers and transported to the crusher. Tipper requirement: Average load per cycle of the excavator/loader with 3.80/5.70 cum. bucket capacity assuming 33% as swell factor, 80% as the fill factor and 1.80 as the density for limestone works out to be: For Excavator = 3.80 x 0.8 x 1.80/ 1.33 = 4.11 tones
For Loader = 5.70 x 0.8 x 1.80 / 1.33 = 6.17 tones. Taking average carrying of a tippers as 10 & 20 tonnes, total number of cycle required to fill a truck works out to
For Excavator = 10/ 4.11 = 2.43 say 3.0 For Loader = 20 / 6.17 = 3.24 say 3.0
Taking an average cycle time of an loader as 30 seconds, assuming 70% as coefficient of utilization, the time required for an excavator & loader to fill a 10 & 20 tonnes tippers works out to: For Excavator & Loader = 3 x 0.5/ 0.7 = 2.14 or say 2 min. Cycle Time of Tippers for Limestone Spotting Time = 0.5 mins. Loading Time = 5.0 mins. Travel time loaded @ 20 km/ Hr. With avg. distance of 4 km. = 12.0 mins. Unloading Time = 0.5 mins. Travel time Unloaded @ 20 km/Hr. Avg. distance of 4 km. = 12.0 mins. TOTAL = 30 mins. With a cycle time of 30 mins. a tippers will be able to make about 12 trips to the crusher
34
i.e. about 720 tonnes per day with one shift working. Therefore, the number of tippers required for transport of limestone from the face to the crusher works out to 740/720 = 1.02 say 2. Therefore in all 2 tipper/dumpers in operation will be required per day for the mines. Taking 80% as the availability the total number of tippers required for the mine works to be 02 Tippers. DRAINAGE AND DEWATERING The applied lease area is situated nearby sea coast but beyond the 500 m limit of Coastal Regulation Zone so no danger is envisaged this regard. Observation from nearby wells & bore wells in the area reveal that depth of water table is below mean sea level. The working is proposed till 22 MRL and so will not reach mean sea level and hence there will be no interception of water table. Except for the scanty rainfall in this semiarid region, there is no source of water that is likely to be encountered in pits. Rainwater will be harvested/ accumulated in the lower most benches/ level of mined out pits. Accumulated rainwater will act as ground water recharge structure & water harvested will be used for plantation, dust suppression & plat use.

f) Conceptual Mine planning upto the end of lease period taking into consideration the present available reserves and resources describing the excavation, recovery of ROM, Disposal of waste, backfilling of voids, reclamation and rehabilitation showing on a plan with few relevant sections.
General Every mine needs to be planned in a way that the useable mineral is extracted to the maximum extent without causing severe irreversible environmental damages. In the case of the Babarkot Limestone Area; the concept is to take necessary steps in order to keep the area under disturbance at any stage of mining operations to the minimum. And we are operating our mines on the concept of zero waste mining and maximum utilization of low grade mineral so we are in the process of planning to extract the mineral upto 0 mRL in the conceptual stage. Rehabilitation of the mined out area shall be done with least time between damage and repair. The end land use of the mine is controlled by the following factors: - No rejects/waste are generated during mining except windblown sand, hence backfilling towards restoring entire worked out area to pre-mining land use is not feasible for entire worked out area. As it is not feasible to bring the mine pits to the ground level it is not found useful to convert it into agricultural land use. As the area is facing scarcity of water hence found useful to convert the mined out area into rainwater storage. A little part of worked out area can be reclaimed and rehabilitated with sand which exists as capping of area The surrounding areas have very low vegetation discouraging fauna habitats; hence a flora and fauna habitat will be useful. A water body will be a pleasing addition. This will avoid any chance of salinity ingress into the groundwater. Additionally, the rainwater harvested in mined out area shall induce freshwater recharge, thereby improving the quality of the groundwater in the upstream areas. In view of the above, it would be appropriate to convert the mine into a mix of water bodies to stabilize the groundwater with green belt area for ecological and aesthetic restoration. The mine planning and land reclamation shall be carried out to achieve the above aim. The disturbed land will be fully reclaimed/ rehabilitated before abandoning the mine.
i) Exploration- From the nature and extent of the deposit, adequate reserves along with quality have been
proved with certain degree of reliability based on nearby mines pits, boreholes and old pits in the applied area. A handsome quantity of resources has been estimated which to be is proved under mineable reserves for which further exploration is required and hence proposed the same. In this regard, exploration is proposed during the first year of the
36
applicability of mining plan. There has been proposed a total of 20 core bore holes in unexplored area vertically. This will bring the resources within G1 category. The details of proposed bore holes have already been given in chapter – Geology & Exploration.
ii) Excavation- The mining operations during period of mining plan are proposed to be carried out at one
location. Mining shall not be carried out in the area of 7.5 m barrier along the either sides of the public road and boundary line. Permission shall be obtained from competent authority i.e. DGMS to work in statutory boundary barrier along common lease boundaries looking towards conservation of valuable minerals. No other feature is present in the ML area which is likely to affect the design of ultimate working except HT electric line. At places where mining is not feasible due to narrow spaces has also been affected ultimate pit limit. The layout of ultimate pit extension and depth has been designed to reach ultimate angle of 45 degree by keeping bench height 6m, width 4.5m depth upto 0 mRL. The schematic section of ultimate layout of mine working with bench configuration is shown in figure below: -
LEVEL IN METER W.R.T. MSL

Total 34.70 Fresh area of ML shall be taken up for development and exploitation simultaneously. After the entire exhaustion and as backfilling is not envisaged, the voids shall be used for accumulation of rainwater which will be part of rainwater harvesting scheme. Thus the excavated areas will be beneficial to human being, flora and fauna, in this water starved region of Amreli district of Gujarat State. During the entire mine life following activities are proposed to be carried out. 1. Development During this period removal of OB sand is envisaged from fresh mineable area. Other than production activities, routine developmental activities shall be taken place. Mine office and work shop and other necessary infrastructures are already established in nearby mines of same company. 2. Production In due course of time working is proposed upto 0.00mRL with due permission of MoEF. Geo-Technical Study shall be carried out to determine slope stability and accordingly ultimate pit shall be designed and changed. The area have also been identified for working in a block of 5 years upto mine life as shown in Conceptual Plan, Plate No. 7.

iii) Waste Disposal- Since no waste/ mineral reject is available so no dumping is required. Also no sub-grade
limestone will be generated; hence no arrangement is required for stacking the same. On sand is required to be stacked temporarily which ultimately is proposed to be backfilled in worked out area.
iv) Reclamation and rehabilitation - Reclamation
The mining area covering 34.70 ha shall be gradually developed and exploited for limestone. Part of the mined out area is envisaged for backfilling with the available overburden soil. The voids below the general ground level shall be used for storage of rainwater and surface run-off water which could be used for agricultural and domestic purposes in this area. This accumulated water shall be kept suitably fenced off all around. There are plans for developing pisciculture and picnic spot. It is proposed to create four water storages during the mine life. These rainwater storages will cover an area of 34.70 ha. Rehabilitation It has already been mentioned that the area of mining lease is free from any habitation and therefore there will not be any oustees. Afforestation Program Company has a plan to plant saplings of trees and shrubs all along the statutory barrier around the HT line passing through the applied lease boundary. Plantation is proposed to be done at the rate of 1000 saplings per hectare and area 0.5ha per year. Soil, if any removed during mining is proposed to be used for plantation purposed. By the end of this mining plan period, an area of 2.50 ha area under greenbelt shall be developed. When the mine is exhausted completely, entire area of ML will have four large to small water storages and big gardens with trees and shrub, which will be beneficial of human population of the region in Jafarabad Taluka of Amreli District. The relevant help for successful reclamation/ afforestation will be taken from experienced

2.2 UNDERGROUND MINING- Not applicable
41
3.0. MINE DRAINAGE a) Minimum and maximum depth of water table based on observations from
nearby wells and water bodies The applied area is situated nearby sea coast beyond the 500 m limit of Coastal
Regulation Zone. Observation from nearby wells & bore wells in the area reveal that depth of water table is upto or below mean sea level. The water table observed in the peizometers installed in the nearby ML area is -2.0m msl.
b) Indicate maximum and minimum depth of Workings. As it is a case of fresh grant hence no working carried out. c) Quantity and quality of water likely to be encountered, the pumping
arrangements and places where the mine water is finally proposed to be discharged
No ground water intersection envisaged due to mine working upto 22.0mRL during this plan period. No seasonal drains exist in the applied ML area. The rainwater falling in the catchment area of the mine pits is proposed to be stored in the sump proposed to be created and to be used for dust suppression and watering plants. Rainwater shall be required to be pumped out from the mine sump as and when required. Rainwater collected in the mined out area shall be used for mining purposes.
d) Describe regional and local drainage pattern. Also indicate annual rain fall, catchments area, and likely quantity of rain water to flow through the lease area, arrangement for arresting solid wash off etc.
The Babarkot Limestone Area is devoid of any perennial or seasonal river through the area. The rainwater flows as per natural flow in the un-worked area down-stream to the sea. Regionally the drainage of the area is controlled by seasonal rivers Dhantarwadi and Raidi, joined by small nalahs which drain to the backwaters/ Gulf of Khambat in the Arabian Sea, with whatever little precipitation is received in this semi arid region. The recorded average rainfall in area is 819 mm per annum. During the year in which the rainfall is less and consequently precipitation is less it results in drought condition. However, as a precaution towards flash floods due to heavy rains, if any, caused due to cyclonic conditions, sump 500m*300m and 6m deep, has been proposed for storage of rain (sweet) water. Water is being conserved for dry months. Catchment area is quite big as it does not form a part of any major river system due to its proximity to the sea coast. The water is proposed to be used for consumption for dust suppression and plantation. The quality of rainwater remains intact as no effluent is proposed to be mixed with and on the other hand no contamination is envisaged as the mineral limestone is non-toxic in nature.
42
4.0 STACKING OF MINERAL REJECT/ SUB-GRADE MATERIAL AND DISPOSAL OF WASTE
a) Indicate briefly the nature and quantity of topsoil, overburden/ waste and Mineral Reject to be disposed off.
On an average about 1.0m cover of overburden sand is available in the applied ML area. The thickness of overburden sand is comparatively more towards Kovaya villages while the thickness decreases towards village Babarkot which is on higher ground. The entire deposit contains windblown sand and is about minimum 0.5 m and at places even 4m thick. OB sand available is very low in quantity and useless. The OB sand shall be removed separately and shall be used for backfilling as well as for plantation/ green belt purposes. During first five years of working, OB sand shall be removed from fresh area. This shall be disposed of by means of stacking covering an area 1.10ha (110m*140m*6m) near boundary pillars during first five years. The yearly generation/ use of overburden sand is furnished in table below: -

Waste is not available as well either in the form of overburden or in inter-burden. Only OB sand is available which is non – toxic in nature.
b) The proposed dumping ground within the lease area be proved for presence or absence of mineral and be outside the UPL unless simultaneous backfilling is proposed or purely temporary dumping for a short period is proposed in mineralized area with technical constraints & justification.
As the area shall not be available for backfilling hence OB sand removed during first five years is proposed to be utilized for backfilling in future.
c) Attach a note indicating the manner of disposal of waste, configuration and sequence of year wise build up of dumps along with the proposals for protective measures.
Not applicable as no waste is available for backfilling. OB sand shall be temporarily stacked at earmarked site.

6.0 PROCESSING OF ROM AND MINERAL REJECT
a) If processing/ beneficiation of the ROM or Mineral Reject is planned to be conducted, briefly describe nature of processing/ beneficiation. This may indicate size and grade of feed material and concentrate (finished marketable product), recovery etc.
The ROM are proposed to be utilized for cement manufacturing by dry process. There is no wet processing or beneficiation necessary to upgrade the limestone. The ROM material is directly fed to the crusher installed outside the ML area for further process.
b) Give a material balance chart with a flow sheet or schematic diagram of the processing procedure indicating feed, product, recovery, and its grade at each stage of processing.
Not applicable c) Explain the disposal method for tailings or reject from the processing plant. Not applicable d) Quantity and quality of tailings /reject proposed to be disposed, size and capacity
of tailing pond, toxic effect of such tailings, if any, with process adopted to neutralize any such effect before their disposal and dealing of excess water from the tailings dam.
Not applicable e) Specify quantity and type of chemicals if any to be used in the processing plant. Not applicable f) Specify quantity and type of chemicals to be stored on site / plant. Not applicable g) Indicate quantity (cum per day) of water required for mining and processing and
sources of supply of water, disposal of water and extent of recycling Water balance chart may be given.
The water for mining is required in terms of industrial use and domestic use. Domestic water (2 KLD) requirement shall be fulfilled from existing Desalination & RO plant installed within cement plant area and water for industrial use (15KL) shall be sourced from mine sump water of nearby mines. Water is sourced from the sea for overall domestic use of entire plant. Domestic waste water generated is treated in the STP and used for industrial use. Spraying of water on the haul roads will not generate any waste water as the same would evaporate or percolate to lower levels through the strata below (which are normally porous). There shall be no recycling of water on this account. No waste water is proposed to be discharged from the applied area. The water balance for the mine is as below: -
Water Requirement per day Discharge Activities Quantity (m3) Quantity (m3) Domestic Use 2 Zero Industrial Use 15 Zero Total Requirement 17 Zero

(Refer Annexure-XIII for latest environment monitoring reports) CLIMATE & METEOROLOGY Climate The climate of the area is characterized by general dryness (except during the south-west monsoon season) and hot summer. The temperature ranges from 9.4oC to 42.2oC. The rainy season extends from mid June to mid September. Rainfall The mean annual rainfall has been recorded as 819 mm. The relative humidity is generally high during the period from June to September and is least during the January-February period. Wind Speed & Direction The predominant wind direction from May to September is from West and South West while in the post monsoon and winter it is from North East to South East. In April to June and October the sky remains cloudless or lightly clouded and moderately clouded during July to September. Forest There is no forest in the core zone. Wildlife Sanctuary/ National Park etc There is no wildlife sanctuary, National Park etc. in the radius of 10 km. Vegetation: The applied ML area is not having any indications of good vegetation except natural vegetation. The applied ML area is generally devoid of large trees which includes very poor vegetal cover. Acacia nilotica Acacia ninuata, Prosopis juliflora are some of the common species. Besides common trees, natural vegetation grows mostly during monsoon and fades away with the onset of summer. The area does not have rare and endangered species.
c) Human settlements Six villages Kovaya, Vandh, Varahswarup, Babarkot, Bhakodar, Mitiyala, and a town
51
Jafarabad lies within the 5 km radius of applied lease area in all directions which constitutes small size human settlements. The villagers are mostly employed in agricultural work. Some people are engaged in other businesses. In the study area, i.e. the area falling within 5 km from the mine, there are 5 inhabited revenue villages. The entire buffer zone of 5km radius falls within Amreli District of Gujarat.

f) Area reclaimed/ rehabilitated by applicant = nil g) Area afforested by applicant = 2.50 ha
ii) Air quality- Air Quality
Air or atmosphere pollution is another significant consequence of mining operations. Basically Suspended Particulate Matter (SPM) is the only pollutant inducted into the atmosphere and the mining activities may contribute to the SPM concentration. Monitoring of Air Quality For effective control over the quality of air sampling stations has been established in the surrounding. It is proposed to be established AAQ samplings stations within the applied area. Samples will be collected periodically and analyzed. An analysis record of the samples will be maintained in a bound paged book to ensure that the quality of ambient air is within the permissible limit. a) Following standards in ambient air quality of mining area shall be achieved
Parameters Standard for Ambient Air for 24 hours average
PM10 100 ug/M3 PM2.5 60 ug/M3 SO2 80ug/M3 NOx 80ug/M3
Data on ambient air quality shall be regularly submitted to MoEF, SPCB/ CPCB once in six months. b) Vehicle emission shall be kept under control and regularly monitored. Measures shall be taken for maintenance of vehicle used in mining operation and in transport of mineral. The vehicles not to be overloaded. c) Fugitive dust emission from all sources shall be controlled regularly. Water spraying on
53
haul roads, loading & unloading and transfer points shall be provided and maintained. d) Persons working in dusty area shall wear protective respiratory devices and they shall be provided adequate training and education on safety and health aspect. e) Stabilization of backfilled area, if any by suitable plantation. g) Maximum use of surface miner h) Controlled blasting by competent persons i) Periodic monitoring of ambient air quality
iii) Water quality Water Quality
No ground water intersection is envisaged due to mining operations in the applied mining lease area. Rainwater accumulated in the mine sump, if required will be quite away from mining operations. In such no adverse impact on ground water as well as on surface water is envisaged. Monitoring of Water Quality a) Quality of water to be monitored periodically as per norms prescribed by CPCB and in compliance of MoEF & SPCB. b) Results of water to be reported to concerned authority c) Monitoring of water level through piezometers to be installed, if required in the area d) Relevant remedial action to be taken in case of abnormal results
iv) Noise levels Noise Level
The present noise levels as revealed by noise survey conducted at various points around the other applied ML area, noise levels are generally within the permissible limit. The noise levels shall be kept as detailed below: - (i) Day time - 75 dBA (ii) Night time - 65 dBA Monitoring of Noise Level a) Measures shall be taken for control of noise levels below 85 dBA in the work environment. Workers should be provided with ear plugs/ muffs. b) The operator's cabin would be safe guarded with proper enclosures to reduce the noise levels c) A thick tree belt would be provided in phased manner around the periphery of the mine to attenuate noise d) The prime movers/diesel engines would be proper designed and will be properly maintained e) Period monitoring of noise level as per norms
v) Vibration levels (due to blasting) Noise and vibrations are intimately connected to each other. One is the cause for other.
In opencast mines, blasting is resorted to loosen the material. The method of blasting in the Babarkot Limestone Area has already been described in Chapter “Mining”. Vibration study shall be carried out periodically during mining course. Mitigation Measures: 1. Controlled blasting practise will be proposed by competent persons 2. Modern technique i.e. NONEL shall be in practise to control vibration and flying
rocks 3. Secondary blasting shall be avoided by means of using rock breaker 4. Periodic monitoring to know intensity of induced vibration
54
vi) Water regime As the matter of fact the applied area of Babarkot Limestone is not part of seasonal or
perennial drains. Direct precipitation as well as water from catchment area shall be accumulates in sump to be created. There is no chance of disturbance of water course due to mining in the past and also in the future. Underground Drainage No source of groundwater was found in the core zone. The ground water table is quite below the present general ground level and proposed working during the period of this mining plan. Hence no ground water intersection is envisaged during this mining plan period. Prior permission, if required necessary shall be obtained from competent authority for working proposed below 2.0mRL. Mitigation Measures: a) Regular monitoring of ground water by establishing network of Piezometer at suitable locations in the project area in consultation with Gujarat Water Resources Development Corporation Ltd., Gandhinagar. The frequency of monitoring shall be four times a year. Data thus collected shall be sent at regular interval to competent authorities. b) Ground water table not to be punctured c) Wherever required, bund shall be provided around the working pits A full-fledged separate environmental management cell with suitable qualified personnel has been set-up under the control of a Senior Executive.

To evaluate the effectiveness of environmental management programme regular monitoring of the important environmental parameters will be taken up. A team of qualified and trained personnel is engaged to carry out the task and be responsible for the following: Collecting water and air samples, work zone monitoring for air pollutants. [1] Analyzing the water and air samples [2] Implementing the control and protective measures [3] Coordinating the environment related activities within the mine [4] Green belt development etc. [5] Monitoring the progress of implementation of environmental management programme [6] An area where employment opportunities presently are limited. With mining activities, local people will have a lot of direct and indirect employment avenues opened up due to enhancement in production. Hence, enhancement in mining activities will have a beneficial effect on socio
64
economic condition with schools, hospital and markets coming up in otherwise almost barren area. [7] Good housekeeping will improve the working conditions. [8] Regular cleaning of roads to avoid accumulation of dust/ water. [9] Regular cleaning/ washing of shop floors. [10] Maintaining nurseries and development of greenbelt around the mining site, the plantation of trees are not only for the suppression of dust and pollutant transportation but it is also for enhancing the aesthetic values. [11] Avoiding accumulation and dumping of waste and damaged equipment. [12] Maintaining hygienic condition in the canteen, drinking water sources and toilets. [13] Occupational safety and health is another important factor in the mining area and following steps are to be taken. [i] Audio visual dissemination of information on safety, embracing risks associated with their profession, safety regulation will be adopted meticulously [ii] Organization of safety weeks. [iii] Seminars/ workshops related to industrial safety. [iv] Mandatory use of personal safety equipment like helmets, goggles, gloves, masks muffs etc. wherever required. [14] Non-destructive testing of all equipment and machinery will be carried out at regular intervals. 8.4 Disaster Management and Risk Assessment: This may deal with action plan for high risk accidents like landslides, subsidence flood, inundation in underground mines, fire, seismic activities, tailing dam failure etc. and emergency plan proposed for quick evacuation, ameliorative measures to be taken etc. The capability of lessee to meet such eventualities and the assistance to be required from the local authority may also be described. As the area is close to coast there are chances of hitting of cyclone which may cause: [1] Flash floods [2] Damage of life and property [3] Disruption of road & telecommunication facilities. [4] Lightning The following points will be followed in this Progressive Mine Closure Plan for disaster management: [1] Working of mine as per approval. [2] Working as per applicable Rules & Regulations [3] Responsibilities from top to bottom line in case of high-risk accidents have been well defined. [4] Action plan has been made for quick evacuation in case of high-risk accident and natural disaster. 8.5 Care and maintenance during temporary discontinuance: An emergency plan for the situation of temporary discontinuance due to court order or due to statutory requirements or any other unforeseen circumstances may indicate measures of care, maintenance and monitoring of status of discontinued mining operations expected to re-open in near future. In case of any temporary discontinuance due to court order or due to statutory requirement or any other unforeseen circumstance following measures for care and maintenance and monitoring of status shall be taken.
