2.2 Geology The rocks in these region form part of the marine sedimentary formation of Cretaceous Age referred to Uttathur stage. The Uttathur formation is the oldest stage among the cretaceous formation. The Uttathur formation is widely spread all along the Southwest boundary over 9 to 10 kms. The general strike of the occurrence is North-South and width is ranging about 200 to 300 mtrs. The observed depth of occurrence is about 40 mtrs. Granite and granite gneisses form the basement which one of Archean age. The order of superposition of the rocks is clearly observed by the presence of overlying conglomerate horizons above which deposition of cretaceous age took place. Local Geology : The limestone deposit in Kallakudi and Kovandakurichi area is of sedimentary origin and referable to Uttathur Stage of upper cretaceous formation and are of marine transgressional series. From the field relationship it is observed that the sedimentary process involved could be tectonics upheaval resulted in faulting which is clearly manifested in Kovandakurichi and Kallakudi quarries as two sets of almost E-W and NNE-SSW trending normal fault system. Geological succession in the Kallakudi & Kovandakurichi limestone deposit:

3.3 Methodology Adopted The methodology adopted are discussed below : Micrometeorology : As a part of the study, the micrometeorology and microclimatic parameters were

recorded by installing a weather monitoring station (Envirotech WM 200) near the Site at 6.0 m height. Data of wind velocity, wind direction, ambient temperature, relative humidity, cloud cover and atmospheric pressure were recorded at hourly intervals along with rainfall during the monitoring period. Ambient Air Quality : The study area represents the Industrial, Residential, Rural and other Areas with

respect to Revised National Ambient Air Quality (NAAQ) Norms stipulated by CPCB. Calibrated Fine Particulate Samplers (Envirotech APM 550) were used for monitoring of PM2.5/PM10. Calibrated Respirable Dust Samplers (Envirotech APM 460 with flow rate ranging between 1.2-1.45 m3/min) are used for monitoring of PM10 and SPM. Gaseous samples are collected by integrated gas sampling assembly (Envirotech APM 411). A tapping provided in the hopper of the sampler is utilised for sampling of SO2 and NOx, with proper flow controller and a flow of 1.0 l/min. Particulate Lead (as Pb) is determined from the glass micro fibre filter papers used for PM10 & SPM monitoring.

PM2.5 & PM10 : The APM 550 system is a manual method for sampling fine particles and is based on

impactor designs standardized by EPA for Ambient Air Quality Monitoring. Ambient Air enters the APM 550 system through an omni-directional inlet designed to provide a clean aerodynamic cut point for particles greater than 10 microns. Particles in the air stream finer than 10 microns proceed to a second impactor that has an aerodynamic cut point at 2.5 microns. The air sample and the fine particulates existing from the PM2.5 impactor is passed through a 47mm dia filter. Teflon filter membrane that retains the FPM. The APM 550 system allows removal of the PM2.5 impactor from the sample stream so that the same system may be optionally used as a PM10 sampler also. SPM : The parameter SPM has been excluded from the revised NAAQ Norms for Ambient Air Quality. However, to have the baseline status of total particulates, SPM was included for the monitoring. Respirable Dust Sampler (RDS) is attached with a cyclone. Air enters a vertical cylinder with a swirling (vortex) motion and particles larger than design cut-off (i.e. 10 um diameter) are deposited on the inner surface of the cylinder, whereas particles below 10 microns are deposited on the Whatman GF/A microfibre filter paper. RPM was calculated by taking the difference between final and initial weights of the filter paper and dividing by volume of air sampled at STP conditions. SPM was calculated by taking the difference between final and initial weights of the dust collection bottle plus filter paper and dividing by volume of air sampled. SO2 : Modified West & Gaeke method (spectrophotometric) was adopted. SO2 was collected in a

scrubbing solution of sodium tetrachloro mercurate (TCM) and was allowed to react with sulphamic acid, formaldehyde and then with pararosaniline hydrochloride. The absorbance of the product red-violet dye was measured using UV Visible Spectrophotometer at a wavelength of 560 nm. Concentration of SO2 was calculated by multiplying the absorbance with calibration factor and dividing by volume of air sampled. NOx : Jacob and Hocheiser modified method was adopted. Nitrogen oxides as nitrogen dioxide were collected by bubbling air through sodium hydroxide-sodium arsenite solution to form a stable solution of



sodium nitrite. The nitrite ion produced during sampling was determined spectrophotometrically (at 540 nm) by reacting the exposed absorbing reagent with phosphoric acid, sulphanilamide and N (1-naphthyl) ethylamine dihydrochloride. Concentration of NOx was calculated as described in SO2 measurement.

Ammonia : Indophenols method (APHA Method 401, Air Sampling and Analysis, 3rd Edition) was adopted. Ammonia in the atmosphere is collected by bubbling a measured volume of air through a dilute solution of sulphuric acid to form ammonium sulphate. The ammonium sulphate formed in the sample is analysed colorimetrically by reaction with phenol and alkaline sodium hypochlorite to produce indophenols. The reaction is accelerated by the addition of Sodium nitroprusside as catalyst. Ozone : IS:5182 Part IX (Methods for Measurement of Air Pollution - Oxidants)/ APHA Method 410 was adopted. Micro amounts of ozone and the oxidants liberate iodine when absorbed in a 1% solution of potassium iodine buffered at pH 6.8 ±0.2. The iodine is determined spectrophotometrically by measuring the absorption of tri-oxide ion at 352 nm. CO : Envirotech APM 850 Organic Vapour Samplers are used for CO monitoring. Standard MSA tubes are used for monitoring carbon monoxide. A measured volume of air is passed at the flow rate of 100 to 200 ml/min for 1 to 8 hours and the colour change (yellow to green) in indicating gel filled in the detector tubes and is matched with the colour chart provided with detector tubes for finding out CO concentration. HC : A digital imported Drager Multiwarn-IIBD sampler was used for monitoring HC directly. Benzene : The charcoal tubes are available in different sizes and contain varying amount of activated charcoal. The ambient air was sucked through the tube using a low flow sampler used for collection of BTX sample in a way that results in an enrichment of the relevant substances in the activated charcoal. Desorption of the adsorbed benzene was done using Carbon disulphide (CS2). The substances desorbed in CS2 were analyzed by capillary Gas Chromatography. Benzo (a) Pyrene (BaP) is one of the most important constituent of PAH compounds and also one of the most potent carcinogens. This can be measured in both particulate phase and vapour phase. In the vapour phase the concentration of B(a)P is significantly less than the particulate phase. Therefore, more care to be taken for the measurement of Benzo(a) Pyrene in the particulate phase. It is based on BIS method IS 5182 (Part XII). This method is designed to collect particulate phase PAHs in ambient air and fugitive emissions and to determine individual PAH compounds using capillary Gas Chromatography equipped with flame ionization detector. Nickel and Arsenic : The Atomic Absorption Spectroscopy (AAS) technique makes use of absorption spectrometry to assess the concentration of an analyte in the sample. The method is based on active sampling using PM10 High Volume Sampler and then sample analysis is done by atomic absorption spectroscopy. Particulate Lead : The exposed glass fibre filter papers were cut into small pieces and to it 100 ml distilled water and 10 ml nitric acid were added and heated on a hot plate for 4-6 hours. The clear solution obtained after digestion was filtered and made upto 25 ml and were analysed on an Atomic Absorption Spectrophotometer (AAS) employing Lead Hollow Cathode Lamp. Concentration of lead was calculated by taking the result obtained from AAS analysis and dividing it with the volume of air sampled.

Noise Levels : Noise levels were monitored at all air monitoring locations during day time as well as night time in a day. B&K type Lutron SL 4001 with an internal calibrator and wind screen was used. The sound level meters are in accordance with IS:9779 and IEC 651 standards for noise survey. The built-in internal oscillation system 1 KHz sine wave generator (Bruel & Kjaer multi-function acoustic calibrator-Model 4226) is used for on the spot calibration at 94.0 dB(A) at 1000 Hz. The basic unit of measurement is A-weighted sound level, the most widely used scale. The measurements are taken in the fast mode and were sampled to yield statistical informations such as Leq (equivalent noise level). Water Quality : Water samples of both surface and ground waters were collected during the survey period and analysed for physico-chemical and bacteriological parameters. Parameters like pH, conductivity, temperature, DO, etc. were measured in the field itself while collecting the samples using a microprocessor based Portable Water Analysis Kit (Elico Model PE136). Samples for chemical analysis were collected as per IS:2488. Sterilised bottles were used for collection of water samples for bacteriological analysis.

Soil Quality : Soil samples at 3 depths viz. 0-30 cm, 30-60 cm and 60-90 cm were collected using sampling augers and field capacity apparatus. Soil extraction (1:2) were used for analysis of physical, chemical and other parameters. Calibration : The monitoring and analytical instruments are being calibrated periodically. The correction factors, if any, are being used in computation of the data.

limit value of 6 ng/m3 (annual mean). Nickel (Ni) concentrations were monitored <0.1 ng/m3 at all the monitoring locations against the NAAQ limit value of 20 ng/m3(annual mean). Benzene (C6H6) concentrations were monitored <1.0 ng/m3 at all the monitoring locations against the

NAAQ limit value of 5000 ng/m3 (annual mean). Benzo(a) Pyrene (BaP) concentrations were monitored <1.0 ng/m3 at all the monitoring locations against the NAAQ limit value of 1.0 ng/m3 (annual mean).. While comparing with the National Ambient Air Quality (NAAQ) Standards revised as per GSR 826(E) dated

16.11.2009, all monitored values were found to be well within the respective limit values for 24-hourly periods for Industrial, Residential, Rural and other Areas.

3.6 Dustfall Rate Dustfall measurements were carried out as per IS:5182 Part (i) at ML Area covering 30 days in the Season. The dustfall rate was monitored at the mine area and the monitored values are presented in Table 3.3.



The mean Dustfall in the mine vicinity was monitored to be 7.3 MT/km2/month which is well within the desired limit of 10 MT/km2/month (Ref. : NEERI Manual). The trace metals Pb, Hg and Cd levels in the collected dust were found to be below their detectable limits.

3.7 Noise Levels Industrial activities and the traffic flow are main source of Noise in the area. The abstract of collected noise data are presented in Table 3.4. Workzone noise levels (Mine not in Operation with adjacent Mines in operation) in the Mine were ranging from 33.8 dB(A) to 92.2 dB(A) during day times and from 32.9 dB(A) to 90.5 dB(A) during night times on the monitoring day with Leq-d level of 44.1 dB(A) and Leq-n level of 41.8 dB(A) which were found to be well within OSHA Standard of 85 dB(A) for 8-hours exposure. Ambient noise levels were ranging from 31.8 dB(A) to 97.1 dB(A) during day times and from 31.5 dB(A) to 98.2 dB(A) during night times on the monitoring day. Day Equivalent Noise (Leq-d) level was found to be 42.1 dB(A) and Night Equivalent Noise (Leq-n) level was 40.2 dB(A). While comparing with the MoEF&CC Leq Norms for day and night times, the monitored ambient noise levels were well within the limit values of <55 dB(A) during day times and <45 dB(A) during night times, for Residential Areas.

3.8 Water Environment 3.8.1 Hydrogeology The normal annual rainfall over the Trichy District varies from about 730 mm to about 900 mm (CGWB South Eastern Coastal Region, Technical Report Series-February 2008). It is the minimum around Musiri (731.9 mm) in the western part. It gradually increases towards north, east and south and reaches a maximum around Manapparai (908.5 mm). The major part of the district is underlain by Archaean Crystalline Metamorphic complex. The important aquifer systems encountered in the district are classified into : v Fissured, fractured and weathered crystalline formations consisting of Charnockites, Granite

Gneisses and v Unconsolidated and Semi-consolidated formations. The unconsolidated and semi consolidated formations in the district include shales, sandstones and clays of Jurassic Age (Upper Gondwana), Marine sediment of Cretaceous Age, Sandstones of Tertiary Age and Recent Alluvial formations. As the Gondwana formations are well compacted and poorly jointed, the movement of ground water in these formations is mostly restricted to shallow levels. Ground water occurs under phreatic to semi confined conditions in the inter-granular pore spaces in sands and sandstones and the bedding planes and thin fractures in shales. In the area underlain by Cretaceous sediments, ground water development is rather poor due to the rugged nature of the terrain and the poor quality of the formation water. Quaternary formations comprising mainly sands, clays and gravels are confined to major drainage courses in the district. The maximum thickness of alluvium is 30 m whereas the average thickness is about 15 m. Ground water in these formations is being developed by means of dug wells and



filter points. The water bearing properties of crystalline formations which lack primary porosity depend on the extent of development of secondary intergranular porosity either through weathered or fracturing. These aquifers are highly heterogeneous in nature due to variations in lithology, texture and structural features even within short distances. Ground water generally occurs under phreatic conditions in the weathered mantle and under semi-confined conditions in the fissured and fractured zones at deeper levels. The thickness of weathered zone in the district is in the range of 2 m to 25 m. The prominent lineaments trend in E-SW, NNE-SSW, NW-SE and E-W directions. Some of these fracture zones persist to depths and may form potential aquifers in the area. Productive joints have been encountered down to a depth of about 100 m bgl in the wells drilled for rural water supply by the Ground Water Department and Tamil Nadu Water Supply and Drainage Board. The yield of these wells at the time of drilling and development ranged from less than 1 lps to 10 lps. The depth of drilling in the district through outsourcing for drought proofing work was in the range of 92-200 m bgl. The wells encountered three to five fracture zones with two fracture zones down to 50 m and two fracture zones in the depth range of 100 – 150 m and one fracture zone deeper than 150 m. The yield of these wells varied from <1 lps to 9 lps. Dug wells are used extract groundwater from weathered formation while deeper fractures are tapped through bore wells and dug cum bore wells. The yield of large diameter wells in the district, tapping the weathered mantle of crystalline rocks or the unconsolidated formations ranges from 200 lpm to 900 lpm for drawdowns ranging from 0.4 to 2.5 m. The wells tapping the deep seated fracture system can yield about 1-5 lps and can sustain a pumping of 6-8 hrs. a day. As per CGWB, the ground water Stage of Development of Pullambadi Block is 49% (<70%) and falls in Safe Category. Characteristics of Limestone Aquifer : Pumping test has been conducted in a bore well near the mines in the top limestone aquifer to study its aquifer characteristics. The results of the pumping test are given below :

Pumping Test Results

Discharge – in lpm 350 Time in min. 1102 Drawdown in m 43.5 Specific Capacity in lpm/m drawdown 8.05 Transmissivity, m2/day 2.63

From the above aquifer parameters, it is evident that the limestone aquifer has poor in transmitting capacity of groundwater and the cone of depression is confined within the mine area. 3.8.2 Water Quality The monitored water quality data are given in Tables 3.5-3.6 and the abstract of those data are given in Table 3.7. The surface waters were monitored with neutral pH in the range 7.65-7.77, agreeable colour, taste and odour. The surface waters were having DO levels in the range 4.4-5.0 mg/l. TDS values were monitored



in the range of 480-580 mg/l. Chloride values ranging from 93 mg/l to 124 mg/l. Iron content was found to be in the range 0.10-0.12 mg/l. Oil and grease, phenolic compounds, cyanides, sulphides and insecticides were found to be absent. Trace metals were found to be below their detectable limits. Monitored low BOD (<1 mg/l) and COD (8-14 mg/l) values indicate that the surface waters were not polluted due to any mining activity. In general, the water quality of surface waters were found to be within the prescribed CPCB norms for surface waters. The pH values of the ground waters were ranging in between 7.55-7.84. TDS values were monitored in the range of 430-750 mg/l. Chloride values ranging from 94 mg/l to 188 mg/l. Iron content was found to be in the range 0.07-0.18 mg/l. Oil and grease, phenolic compounds, cyanides, sulphides and insecticides were found to be absent. BOD and COD values were monitored in lower levels. Trace metals were found to be below their detectable limits. In general, the water quality of ground waters were found to be within the prescribed IS:10500 Norms for Drinking in the absence of an alternative source. The pH value of the Mine Pit water (accumulated rain water) was found to be 7.84. TDS value was 750 mg/l. Chloride value was 188 mg/l. Iron content was found to be 0.18 mg/l. BOD and COD values were monitored in lower levels. Oil & Grease value was found to be Nil. In general, mine pit water quality was found to be within the prescribed TNPCB Norms for Onland irrigation.

3.9 Land Environment 3.9.1 Soil Status The collected soil quality data are given as Table 3.8. Soils with medium compaction and silty loam texture are predominant in the study area. Soil pH values were found to be in alkaline range and Electrical Conductivity values were in the range 1.24-1.61 mmhos/cm. There was low moisture at all the monitoring locations. Low levels of Nitrogen, Phosphorous and Potassium (NPK) values were monitored at all locations. Sodium Absorption Ratio was in the range 2.58-3.56 (desirable value being <5). There was no heavy metals intrusion/leaching into the ground strata. Wilting coefficient in significant levels would mean that these soils would support the vegetation, if amended suitably. The soil water properties reveal that the soil will suit for salt tolerant and semisalt tolerant plants.

3.9.2 Land Use Pattern For Land use study of the Study Area, IRS P6-LISS III- FCC dated 16th Jan. 2016 Satellite digital data NRSA, Hyderabad was used (Fig. 3.5). Visual interpretation technique has been adopted for land use classification based on the interpretation keys suggested in guidelines of NNRMS, Bangalore. Level-3 Classification with 1:50,000 scale was made for the preparation of land use mapping (Fig. 3.6). Dry crop land occupies the majority of the study area (about 57.18%). The wet crop is noticed along the flood plains and is about 8.32%. Water body occupies about 8.55% and about 4.08% of the study area is covered by built-up land. About 2.32% land remains fallow. Mines occupies about 0.66% of the study area. The salt affected land occupies about 5.00%. About 5.87% of the study area is occupied with plantations. The Revenous land occupies about 3.78% of the study area and 4.14% land is with scrub whereas 0.10% land is without scrub.

4.0 Anticipated Environmental Impact and Mitigation Measures

4.1 Identification of Impacts The Environmental Impacts are categorized as primary or secondary impacts. Primary impacts are those which are attributed directly to the project and secondary impacts are those which are indirectly induced by the proposed Project. Any Project would create impact on the environment in two distinct phases : v Construction Phase which may be regarded as temporary & short term and v Operation Phase which would have long term effects. The impacts have been assessed for the Project assuming that the pollution due to the existing industrial

and mining activities has already been covered under baseline environmental status.

4.2 Impacts during Construction Phase This is an existing Operating Mine and it does not involve any establishment or construction. Thus, the impacts during the Construction Phase is Nil.

4.3 Impacts during Operation Phase 4.3.1 Land Use The area of an extent of 0.285 Ha is under Mining. Opencast Mining by adopting Non-conventional method is adopted. There is no Drilling and Blasting and thus, no ground vibration. The mining will reach the ultimate depth of 31.24 m bgl at Conceptual Stage. The excavated area shall be around 0.173 Ha at the end of mining operation. The mined out pit area will be converted into artificial pond to harvest rain water. About 0.112 Ha (39.3%) will be under Green Belt, pertaining to this particular Lease. Mitigating Measures : v Construction and maintenance of garland drains around mine area is being carried out periodically. v Green Belt is developed to control fugitive emissions and to arrest / prevent soil erosion. v After the mine reaches the ultimate depth, mined out pit will be utilized as Water Reservoir for ground

water recharge of the area as well as for local public use. v Proper fencing of the mined out pit will be made. v Securities are employed to stop unauthorized entry to the mine area.

4.3.2 Traffic Volume Mining personnel of 10 persons are visiting the mine with their own mode of transportation. The mined out ROM is transported by 25 Tons Taurus to the Cement Plants @ 6 trucks/Annum through the existing Highways.



Mitigating Measures : v Security Guards are deployed to handle the inward and outward vehicles from the mine. v Loaded Tippers are fully covered with Tarpaulin. v Restriction of over loading is imposed. v Restriction of Truck parking in the Public Road is adopted. v Speed restrictions is imposed. v Regular and preventive maintenance of transport vehicles are carried out. v Compliance to ‘Pollution under Control’ Certification is ensured. v Green Belt along the haul road is developed.

4.3.3 Fugitive Emissions The excavation, loading and transporting activities generate both fugitive dust emissions and smoke from Mine Machinery and Tippers. Emissions from all these sources are fugitive in nature and computed to be in insignificant levels.

Mitigating Measures : Fugitive Dust generation in the mine areas are controlled by : v Water sprinkling on the dust generation points, haul roads, etc. v Green belt development along the periphery, haul roads, etc. v Avoiding over loading of trailers/tippers. v Covering of trailers/tippers with tarpaulin during transportation. v Periodical maintenance of trucks/trailers. v Periodical check up of vehicles for ‘Emission Under Control’ measures.

v Periodical maintenance and replacement of worn out accessories in the mine equipments. 4.3.4 Noise & Vibration Non-conventional method of mining is adopted with no Drilling and Blasting. HEMM and Rock Breakers operations generate noise. The noise level within the Mine Equipments, (during operation) is maintained at <85 db(A) at a distance of 1.5 m from the source. Ambient noise level at the nearest boundary is <55 dB(A) during day times and <45 dB(A) during night times i.e. within the permissible limit for residential areas. Mitigating Measures : v Deploying mining equipments shall be with in-built mechanism for reducing noise. v Provision of silencers to modulate the noise generated by the machines. v Providing sound proof operator's cabin of equipments. v Provision of ear muffs/ear plugs to the Workers in higher noise zones. v Green Belt with thick foliage along roads and around lease boundary to act as acoustic barriers.



4.3.5 Water Environment The mine requires about 2.0 cu.m/day raw water which is being met out from mine pit.

Domestic Usage : 0.5 cu.m/day Dust suppression : 0.5 cu.m/day Green Belt development : 1.0 cu.m/day ------------------- Total : 2.0 cu.m/day -------------------

Common workshop facility is there for Kallakudi & Kovandakurichi Mines. There is no trade effluent from the Mine. Only, domestic sewage generation @ 0.4 cu.m/day is being biologically treated in a septic Tank followed by a Dispersion Trench.

Mine Drainage : Annual normal rainfall of the Region is 883 mm. The Region receives 50% of total

rainfall during Northeast Monsoon periods (October-November months) with 20-25 rainy days. Remaining 50% of rainfall occurs during Southwest Monsoon and Transitional Periods with 30-40 rainy days. The Rain water is being collected at the bottom benches of the Pits (5 Nos.) of Kallakudi & Kovandakurichi Mines. During the summer season the pumping will be done in the Pits to drain out around 320 m3 of water per day. The heavy pumping will be done during the rainy seasons (September to December), at the rate of 750 m3 per day, by using 25 HP pump. The water pumped out during the rainy season will be discharged into the near lakes of the villages around the mining areas. The water is mainly used by the villagers for taking bath and for washing purposes only. During rest of the year, the water accumulated in the sump areas is utilized for our afforestation and sprinkling purposes.

4.3.6 Solid Wastes No waste or Sub grade is envisaged in the ML Area. Hence, no area is required for disposal of waste & Sub grade Mineral. No waste or sub grade mineral is expected to be generated during this ensuing Mining Plan period also.

6.0 Risk Assessment & DMP 6.1 Risk Analysis The mine activities, fire, water inundation, electrical shock, natural calamities, etc. are the risks associated with the mining activities. Detailed assessment and mitigative measures are delineated and an effective Disaster Management Plan is also in place. The objective of Risk Assessments are : v Identifying hazardous activities. v Assessment of risk level and severity in different operations. v Identification of control measures. v Setting monitoring process. v Reduce the impact of mishaps of all kinds. v Reduce the inherent potential for major accidents. Methodology of Risk assessment : v Collection of information & identification of hazard. v Classify their severity and probability of occurrence. v Identification of exposed risks. v Assess the risk and risk rating based on

• Probability

• Exposure

• Consequence

• Prioritisation of the risks

• Implementation of control measures

• Monitoring risk assessment

• Evaluation and correction Risk assessment is mainly based on the environmental impact of various parameters. Land contamination : The potential for contamination during operation of mine site is due to waste

dump. There is no Waste Dump in this Mine. Aquatic toxicity : The risk assessment in aquatic toxicity system is based on the total metal concentration in various chemical form or oxidation state. Limestone does not contain appreciable concentration of toxic elements. Acid mine drainage : The mining of limestone does not involve any processing operation by using

chemicals. Hence there is no risk at mine site with regard to control of acid mine drainage. Tailing dam: Tailings are very fine residuals in the chemical processing operation. It is a potential source of environment contamination. In the limestone mining operation there is no beneficiation activity involved which is likely to generate tailings. Hence no tailing dam is proposed.



Human health : The chemicals from tailing dam and waste heaps may severely affect the human health. However, in limestone mining no chemical effluent is generated nor dumped in waste dump. Hence, there is no risk involved to human health due to limestone mining operation. Factors of risks involved due to human induced activities in connection with mining operations are : Removal of Top Soil / O.B and side burden, Excavation of ore and Transportation of ore. Other factors due to natural activities are Fire, Water inundation, Electricity and Natural calamities. The identified risks and their control measures are given in Table 6.1.
