2.2 Brief description of nature of project

The Review of Mining Plan & Scheme of Mining and Progressive Mine Closure Plan in respect of

Gomardih Dolomite Quarry for the period 2018-2020 has already been approved by Director of Mines,

Govt. of Odisha vide his letter NO. MXXII(b)-14/2017/2303/DM, dated 31.03.2017 (Annexure-6).

The mine has also obtained Consent to Operate under Air & Water Act vide letter no. .4148/IND-I-

CON-193 dated 08.03.2016 for production of 0.816 million ton/annum of dolomite and operation of

crushing and screening plant of capacity 1X200TPH with validity till 31.03.2020(Annexure-7).

The mining operation at Gomardih has improved the Socio- Economic front of the area by way of

creating more employment opportunities, establishing ancillary facilities, shopping centre, educational

& medical facilities thereby improving the general standard of living in surrounding area. Moreover, it

has been planned to produce 0.816 MTPA of dolomite to meet its captive as well as long term domestic

sale commitments remaining within the existing Environmental Clearance limits.

2.3 Need of the Project

Being steel, as an essential commodity for the Infrastructural development, the concern industry is now

growing in an accelerated fashion. For steel making, dolomite is used as flux, Dolomite produced at

Gomardih Dolomite Quarry is being utilised in various steel plants for being used as a flux in steel


5

making. It is primly used for captive consumption in the Steel Plant at Jamshedpur, Ferro Alloys plant

& Sponge Iron Plant at Joda and Tata Metaliks at Kharagpur. M/s Steel Authority of India Ltd is a

prime user of dolomite of Gomardih from public sector. Besides, it is catering to the requirements of

other needy industries. Further, company has its proposal to make use of dolomite at its green field

projects like Kalinga Nagar Steel Plant and Ferro Alloys Complex at Joda & Gopalpur.

2.4 Demand- Supply Gap & Future Outlook

Over 95% of the total production of dolomite finds outlet mainly in iron & steel and allied industries.

The importance of high purity dead-burnt dolomite bricks for lining LD furnaces has gained ground

due to LD process of steel making. At the same time, a few of the steel plants have dispensed with the

use of dolomite pin blast furnace. Mini-steel plants generally require dolomite for fettling and refractory

purpose only. The resources of the refractory grade dolomite in the country are meagre and this type of

material is in short supply but very much required for making tarbonded dolomite bricks. Therefore,

intensive search is needed in non-Himalayan regions for locating deposits of massive non-crystalline

dolomite, containing less than 2.5% R2O3 for use in tar-dolomite bricks required for lining of LD steel

furnaces. The Sub- Group - II of the Working Group on Minerals for the 12th Plan has recommended

the exploration of low silica dolomite in the states of Andhra Pradesh and Odisha which may be initiated

by the State DGMs. The Sub-Group has estimated the apparent domestic demand of dolomite at about

9.46 million tonnes at 9% growth rate by 2016-17.

2.5 Imports vs. Indigenous production

The production of Dolomite in India during the year 2010-11 was 5.01 tonnes. Chhattisgarh, the leading

producing of dolomite accounted for 27% of total production in 2010-11, followed by Odisha (22%),

Andhra Pradesh (21%) Jharkhand and Karnataka each contributed about 8% of total production. The

remaining 14% was jointly shared by Gujarat, Madhya Pradesh, Maharashtra, Rajasthan and

Uttarakhand. The requirement of low silica dolomite is increasing in steel plants and steel plants are

drawing supplies of low silica dolomite from Bhutan, Thailand and UAE.

2.6 Export Possibility

The production of Dolomite in India during the year 2010-11 was 5.01 tonnes. Dolomite is consumed

by iron & steel, ferro-alloys, fertilizer, glass, alloy steel and other industries. The total consumption of

dolomite in 2010-11 was 5.94 million tonnes Imports of dolomite increased considerably to 611,833

tonnes in 2010-11 from 450,979 tonnes in 2009-10. Imports were mainly from UAE (61%) and Thailand

(36%). Exports of dolomite were 22,871 tonnes in 2010-11 and exports were mainly to Nepal,

Bangladesh and Malaysia in 2010-11. Dolomite produced in Gomardih Dolomite Quarry is completely

consumed in steel industry based in India.

2.7 Domestic/ Export Markets

TSL markets its value-added products in both India and overseas markets. The company has set up

depots all over the country to ensure consistent and regular supply of its products to all its customers.

The company has established another company called TMILL for looking after its port operations and

has its establishments at Paradip, Haldia, Visakhapatnam and Dhamra ports.

So far, the major demand for Stainless Steel in our country had been traditionally for the production of

utensils. With the increasing pace of infrastructure development of our country as well as increase in


6

the production in the white goods and automobile sectors, it is likely that there shall be substantial

growth in the domestic markets in the near future.

2.8 Employment Generation

Presently around 45 persons are employed directly by the company at Gomardih Dolomite

Quarry. Around 268 persons are employed indirectly to provide various essential services like

transportation, loading, security etc.

There is no likely increase in overall manpower requirement till 31.03.2020.

3.0 Project Description

3.1 Type of Project

This is a mining project producing dolomite ore of various size and quality. Open cast of

mining method is being practised with shovel dumper combination aided by drilling and

blasting. At first ore is fragmented by blasting then it is loaded by shovel to dumper which

dump ore to plant for processing. The dolomite ore is used for Steel making in its in-house

facilities at Jamshedpur Steel Plant at Jamshedpur, Ferro Alloys plant & Sponge Iron Plant at

Joda and Pig Iron plant at Kharagpur. M/s Steel Authority of India Ltd a Public Sector is a

prime user of dolomite of Gomardih.

There is no proposal for increase in production of dolomite ore compared to the production

limited approved per previous Environmental Clearance. As the earlier Environmental

Clearance was issued as per 1994 notification, the process has been initiated to obtain

Environmental Clearance as per EIA Notification, 2006 in accordance to the Gazette

Notification No. 1385, dated 06th April 2018.

It is proposed to continue mining operation by mechanized open cast as per the rated capacity

already approved.

3.2 Location

The mining lease is located in village Gomardih, Tehsil- Kutra of Sundergarh district in Odisha

state. The nearest railway station is at Sonakhan, which is at a distance of 7kms north of the

ML area. The Sundargarh-Rourkela section of the state high-way is only at a distance of 3 kms.

from the ML area. Gomardih is 49 km from Rourkela and 50 Km from district. The other details

of the ML area are as follows: -

3.3 Details of Alternate Site


8

Since this is a mining project, the site for the mine remains fixed within the mining lease. The

mining lease is surrounded in the north, east and west directions by other mining leases

belonging to other lessees. The topography of the land is flat and far away from any perennial

water bodies. As there is no agricultural land involved, the site is likely to have minimal impact

on the environment. Since all other possible sites involved consist of either agricultural land or

land already leased out to other lessees or approachable only through village roads at a

considerable distance, the proposed site is considered to be the only site suitable for the mining

purpose. The mining operation shall restrict within the mining lease hold area of 372.796 ha.

Besides above, the company has also purchased/ acquired some land (47.695 ha) beyond the

Mining leasehold area for its colony (36.835 ha), Magazine (0.688 ha), access road to colony

from SH-10 (3.759 ha) and Sonakhan railway siding & the road connecting to the siding (6.413

ha) respectively.

3.4 Size & Magnitude of Operation

The mine is presently operated for mining of Dolomite mineral @ 0.637 MTPA of ROM of

dolomite ore though the Environmental Clearance has already been obtained for 0.816 MTPA.

The main reason for less production is attributed to less demand. In the coming years, the Steel

Company has planned to attend it approved capacity to 0.816 MTPA of dolomite ROM to cater

the requirement of captive steel making and ferro alloys making capacities.

3.5 Project Description & Process Details

3.5.1 Geology

3.5.1 (A) Salient Geological Features

The rocks in the lease belong to the Birmitrapur stage of the Gangpur series of Dharwar Age

and form part of the southern limb of the Gangpur anticlinorium. Most of the rocks carry small

amount of impurities like mica and quartz. The overburden increases from eastern to western

side and average thickness of overburden in the area is 6 m. The overburden consists of soil at

the top with several alternate layers of morrum. Few pits and boreholes indicated lateritised

sandy phyllites and banded grey phyllites. The south eastern part of the acquired boundary is

partly covered by phyllites and it is a barren area.

Near the southern boundary of the acquired area, limestone is intercalated with high MgO

bands. This dolomitic limestone gradually continues into the western part of the lease and

finally transforms to dolomite. In the dolomitic limestone, the total insoluble range from 7% to

31.75%, averaging at 15%. This dolomitic limestone, therefore, is not suitable for use in steel

making.

The Dolomite beds at higher levels are highly fissured and jointed with clay filled in the gaps.

At lower levels, the occurrences of joints & fissures are very sporadic except for some solution

cavities. Dolomite is finely crystallized, hard, compact and flaggy in nature.

The lithological characters of different formations in the lease area are as follows:


9

Overburden: Overburden generally consists of soil at the top with several alternating layers of

morrum. On the western portion of the lease area the overburden became comparatively heavier

than the eastern portion. Average thickness of the overburden in the area is 6 meters.

Laterite: Lateritisation is more common in the phyllites. The rock exposed at a few places in

the SE corner of the lease area, is porus and yellowish to brownish red in colour.

Phyllite Zone: There is no outcrop of the rock in the area but some pits and boreholes indicated

lateritised sandy phyllites and banded grey phyllites. The southeastern portion of the area is

covered by the phyllites and hence barren area.

Limestone: A small exposure of crystalline limestone is seen near the southern boundary of

the area. The stone is hard, medium to coarse grained, indistinctly banded grey in colour. The

limestone is intercalated with high MgO bands Dolomite limestone. Width of the stone band is

about 36m. The limestone gradually passes onto the western southern and finally changes to

dolomite. The total insoluble content of samples collected, average to 15.0% with a range from

7.0% to 31.75%. The quality of limestone is given in Table No. 1.

Table No. 1 : Composition of Limestone

S.No. Composition Fraction Percentage

2 AI203 0.78 to 2.15

3 Fe203 0.80 to 1.30

4 MgO 1.43 to 15.00

5 CaO 34.00 to 47.85

Dolomite: Dolomite which occupies major portion of the area crops up at a few places through

the capping of soil. The dolomite beds are highly jointed and fissured. Filling of clayey

materials is often encountered along the joint planes. Such fillings are common at higher levels,

while at depth they are very sporadic except for some solution cavities. The stone is finely

crystalline, hard compact and flaggy in nature. The massive stone is not uncommon. The colour

is grey to dark grey and stone is occasionally banded. Secondary silica and crystalline dolomite

occur in stringers and veins traversing the stone frequently. Chemically the stone shows a very

wide range in its total insoluble content varying from 2.0% to 31.5%. Detailed analysis of

dolomite shows the following ranges in chemical composition.

3.5.2 Mining Operation

3.5.2 (A)Mining Method

There is only one quarry, which have been developed within the leasehold to produce dolomite

ore. Fully mechanized opencast mining is being carried out by employing the shovel-dumper

combination. The height of the benches varies from 4 to 8m and width varies from 10 to 16m.

The present overall pit slope varies from minimum 110 (at the west) to maximum 240 (at the

south). The quarry is 1100m long in E-W direction and 337m wide in N-S direction. The top

and bottom RL of the quarry are 266m and 219m respectively. The Dolomite band is exposed

almost throughout the quarry and only few top benches are cover by overburden. The lease

area has been extended towards west. So, the quarry is advancing from top to downwards and

towards west up to the acquired boundary.

At present, shovels of 0.9-1.2 cum capacity and tippers of ten tonne capacity are in use for

overburden and ore removal. The same mechanized method of mining is proposed to be

continuing during the next plan period. All the benches will be maintained at 8m height during

the plan period. The development of the mine is proposed in such a way that the overall pit

slope of the quarry is maintained within 45°. The supporting equipments like dozer, front-end

loader, explosive van, water sprinkler, pit vehicles for supervision etc. are being used in the

mine.

The ROM is directly fed to the crusher plant. The finished products are stacked in the mineral

storage area at the eastern end of the lease area. About 90% of the dolomite mineral is

dispatched through railway via Tata Sonakhan Railway Siding and rest is dispatched directly

to the customer end by trucks. The company has its own weigh bridge for weighment of the

mineral.

The topsoil generated from the mine is stacked separately at a place earmarked for the purpose.

About 4000cum of top soil is estimated to be generated during the next five years @ 0.30 m of

capping from the area at the western end of the existing pit. The top soil so generated will be


12

used for plantation purpose. The overburden generated from the mine is stacked at the

overburden dump present at the S-W corner of the quarry.

3.5.2 (B) Conceptual Mine Development

There is only one quarry, which have been developed within the leasehold to produce dolomite

ore.

Fully mechanized opencast mining is being carried out to employing the shovel-dumper

combination. The height of the benches will be 8m and width varies from 10 to 16m. The

present overall pit slope varies from 110 (at the west) to 260 (at the south). The quarry is 1100m

long in E-W direction and 337m wide in N-S direction. The top and bottom RL of the quarry

are 268m and 219m respectively.

The present mining operation is confined to the acquired and surface right areas. Opencast

mining with shovel-dumper combination is being practised. Deep-hole drilling along with

conventional blasting techniques is being practised. The same shall continue to be practised

during the conceptual stage of mining. The old version wagon drills had already been replaced

with crawler mounted 100 mm dia drill machines. In order to meet the enhanced production

and excavation volumes, the fleet size shall be increased which has been discussed. The

dimensions of the existing pit are as follows:

Table No. 6

Quarry Length (m) Width (m) Depth (m)

Gomardih Dolomite Quarry 1100 337 49

Based on the fresh estimates of the over burden to be generated for open cast mining up to the

proposed ultimate pit limit, the conceptualized stripping ratio for Gomardih Dolomite Quarry

will be around 7.96 cum of ROM / cum of waste.

Considering the location of the public roads, two separate quarries have been conceptualized

towards the west of the lease, so that these roads are not disturbed. The boundaries of these two

quarries have been conceptualized based on the extent of the measured and inferred resources.

Conventional mechanized method of mining by shovel–dumper combination will be continued.

Considering the continued high production demand, deep hole drilling & blasting and higher

capacity dumpers and excavators shall be put in use as per requirement.

3.5.2 (C) Blasting Method

Broad Blasting Parameter:

The purpose of the blasting is to induce a heaving effect so that, excavator can load the blasted

material easily into dumpers. The requirement of blasting is mainly to break the hard in-situ

dolomite and associated hard rocks which otherwise can not be excavated. Another purpose is

to prepare feed material of (-200mm) size for the crusher plant. The blasting is carried out with

large diameter (83mm) slurry explosive cartridges. Cap-sensitive slurry explosive cartridges

are used as base charge and non-cap sensitive are used as column charge. There is also plan for


13

introducing site mixed emulsion explosives in place of conventional explosives in future for

better blast and safety performance.

For the purpose of safe storage of explosives and accessories required for the blasting

operations, the Gomardih dolomite quarryis has one duly approved explosive magazine located

outside the mine lease hold area at a distance of about 1km away from the southern side of the

lease boundary. The lay out plan of the explosive magazine is attached as an drawing No.MP/

GDQ/R1/18/17 of the scheme document.

The details of burden, spacing and explosive consumption pattern are mentioned below in Table

After charging & stemming of holes, connection is done with detonating fuse. Cord relay of 25

ms / 50 ms are used for delay in case of normal blasting (i.e. if there is no permanent structure

within danger zone not belonging to owner or danger zone is free from intersection of public

road etc.). Cord Relay of 25 ms / 50 ms is fixed between holes along the spacing as well as

between rows. There after shot is fired electrically using approved type of exploders after taking

clearance from guards posted to prevent un-authorized entry for ensuring better safety.

In order to control vibration and fly rock and devise optimum charge parameters, blast vibration

study was conducted by CIMFR, Dhanbad.

In case of controlled blasting (i.e in close proximity to roads, hutments etc) bottom initiation

pattern followed by using the NONELs of down to hole (DTH) of 475 ms in each hole. The

hole to hole connections are made by trunk line delays (TLD) with 17 ms/ 25 ms/ 42ms delay

interval.

The charge per delay in all cases is maintained within 44-48 kg to minimize the ground vibration

and noise caused due to blasting operation.

Types of Explosives: The conventional slurry explosive with 83mm dia are being used for

blasting at present.

Future Plan for Blasting: In future, there is a plan to introduce site mixed emulsion explosive

in the proposed scheme period for improvement in blast performance and safety as well.

Yield: B x S x H x Conversion Factor/Total length drilled


14

Powder Factor: Yield per hole/Podwer Factor

The following precautions will be taken during blasting to reduce vibration and noise:

a) Adequate stemming of holes at collar zone with drill cuttings will be done so as to keep the

stemming length at 30% of the drill-hole depth.

b) Covering the detonating cord in the trunk line with 20 to 25 cm of unconsolidated drill

cuttings before blasting.

c) The powder factor will be kept at 2.7 to 3.0 t / kg

d) To safeguard the residents of the nearby township and villages from the unpleasant

psychological effect of noise and vibration, sound signals will be given prior to blasting.

e) Delay detonators and relays will be in use as usual.

Storage of Explosives: The explosives are brought from our own magazine (3.0 tonne

capacity) located at a distance of 1.0 Km by the explosive van. The explosives are brought in

the working hours and blasting is carried out. The license copies of the magazine and the

explosive van are furnished in the Annexure-8 [License No. E/EC/OR/22/181 (E13233)] and

Annexure-9 [License no. E/EC/OR/25/53(E19248)] respectively.

3.5.3 Mineral Processing

3.5.3 (A) Mineral Processing

The ROM (-200mm) is transported to crusher & screening plant by tipper & dumped into

Hopper. The ROM is also precrushed before feeding into hopper to avoid boulder getting jam

in the apron feeder and thereby improving safety. It is fed into Symon Cone crusher by an apron

feeder. The output of the crusher i.e (-) 75 mm is conveyed to double dake screen having

different aperture size. From double deck screen, various products of different size specification

are screened out and conveyed into 8 nos of surge bins, each having 200 tonne capacity.

Different size products are stored in separate bins. The (-) 8 mm fines produced from the plant

is again screened mechanically in the plant to produce sponge grade dolomite of (-8+4) mm

size. The final product of (-4mm) fines is called sinter grade dolomite which is high in total

insoluble silica..

The present capacity of process plant is 200 tonnes per hour. There shall be neither any change

in beneficiation technology nor is any new beneficiation facility being envisaged during the

next two year’s plan period. The schematic layout of existing Crushing & screening plant is

shown in Annexure-11.

3.5.3 (B) Product Range

The ROM, after crushing, is reduced to -75 mm size in a single stage symon cone crusher. The

plant output product specifications and their approximate recovery percentages after screening

are shown below in Table No. 10.

3.6 Product Dispatch

3.6.1 Brief description of the end-use of the mineral (sale to intermediary parties, captive

consumption, export, industrial use)

The ROM is directly fed to the crusher plant. Dolomite produced at Gomardih Dolomite Quarry

is dispatched to various steel plants for being used as a flux in steel making. It is primly used

for captive consumption in the Steel Plant at Jamshedpur, Ferro Alloys plant & Sponge Iron

Plant at Joda and Tata Metaliks at Kharagpur. M/s Steel Authority of India Ltd is a prime user

of dolomite of Gomardih from public sector. Besides, it is catering to the requirements of other

needy industries. The finished products are stacked in the mineral storage area at the eastern

end of the lease area. About 90% of the dolomite mineral is dispatched through railway via Tata

Sonakhan Railway Siding and rest is dispatched directly to the customer end by trucks. The

company has its own weigh bridge for weighment of the mineral.

3.6.2 Physical and chemical specifications stipulated by buyers

3.6.3 Details in case blending of different grades of ores is being practised or is to be practised

at the mine to meet specifications stipulated by buyers.

The requirement of various customers varies mostly from size specification point of view

chemical composition remaining more or less similar. For example: customers need dolomite

of different size specifications varying as 10-50mm, 10-40mm, 05-60mm, 20-50mm, 15-

50mm, 40-80mm, 02-08mm, 00-05mm etc. Silica and MgO content requirement varies

between 04-05% and 18-20% respectively for all customers. So, the prime plant output (lump,

flux, chips, pea size) are blended in required proportion to meet specific customer requirements

before despatch.

3.7 Waste Generation and Management

3.7(A) Reject Mineral and its Disposal`

The basis of classification of dolomite ore, sub-grade, overburden and mineral rejects is given

in the Table No. 12 below;

Table No. 12 : Different Classification

Ore: Dolomite MgO above 15%, SiO2 % below 8% & Total T.I. % less than 10

%.

Sub-grade Not available

Overburden

Waste ‘Soil’ below the layer of top soil and “lateritic capping” devoid of

economically exploitable mineral.

Rejects Intercalated Bands having MgO% less than 15%, SiO2% above

8% & T.I % more than 10%.

Mineral Rejects Dolomite ore sludge generated from the crusher plant.

The Rejects consisting of MgO% less than 15% is identified by channel and blast hole sampling

and analysis before excavation and mined out separately.

3.7(B) OB Generation and its Disposal

Selection of site for disposal of waste:

The following points are taken into consideration for selecting site for the disposal of waste.

i). Area of disposal should be barren.

ii). Area should be in proximity to the places of work to avoid long hauls/ lead.

iii). The area so selected should not be over land earmarked for township/ other ancillary

facilities connected with the mining or proposed to come up in near future.

Year wise Generation of OB:

The overburden is removed by shovel and dumper combination and stacked at the area

earmarked for the purpose. The area for dumping is established in the phylite zone. The year-

wise quantity of overburden that will be generated in the coming two years is indicated in Table

No. 13

Build up of Dumps:

Height and spread of the dumps will depend on the quantity of waste & the deign parameters

of dumps based upon guidelines issued from various statutory agencies like Director Mines

Safety, Indian Bureau of Mines and Ministry of Environment & Forests. To accommodate

maximum quantity of overburden due to scarcity of space and without affecting the stability,

the dumps are designed to have maximum height of 30m in 3 (three) stages of 10m each. Width

of individual terrace is 10-15m. The overall dump slope will be maintained at about 350.

Further, suitable plantation will be done along the inactive dumps in concurrent manner to help

in enhancing the stability of dumps.

Protective Measures:

a) The gradient of the haul road leading to the top of the dump is maintained at 1:16. Grading

and dozing of the haul road is done regularly.

b) The slope of the benches of the dump is made inward from crest to toe and channels are

made along the toe of each bench channelize the rain water from top to bottm up to the

garland drain.

c) Garland drain and settling pit have also been provided at the toe of the dump. The surface

run-off generated during rain gets settled at the settling pits made for the purpose and clean

water is diverted to the natural nala through the garland drain. The silt of the garland drains

are cleaned at regular interval as per requirement.

d) Toe wall has been provided around the toe of the dump to protect any roll over of boulders

while dumping. The existing toe wall will be maintained and will be extended as per

requirement.

e) Plantation is done at the slope of the dump by making terraces after completion of each

stage.


19

3.7(C) Method of disposal of waste from processing plant

As discussed in the existing method of mining, the fines (-4 mm) generated from the crusher

plant are screened mechanically to -4 +0 mm size. 2% of the total ROM is recovered in sludge

is termed as mineral reject and stacked separately at a separate place earmarked for the same.

3.8 Analysis of Alternatives (Technology & Site)

3.8.1 Selection of Site :This is mineral based site-specific mining project operating since 1962.

Alternative site analysis is not considered. Mining will be carried out within the granted lease

area.

3.8.2 Selection of Technology

(A) Mining Technology : As mentioned in the Para 3.5.2(A), the opencast mining method will

be continued. However, shovels of higher bucket capacity, dumpers to match with the shovels,

drill machines of 100mm dia, dozers and other primary and ancillary mining machineries will

be added to the existing fleet as per the requirement in future.

(B) Mineral Processing Technology

The existing crushing plant has a throughput capacity of 200 TPH of ROM. The crushing plant

is having symon cone crusher, apron feeder, and double deck screen. The crushing plant

operates in two shifts to meet present finished product requirement. There is a proposal to add

a jaw crusher in the plant. It will enhance feed size from current size of 200 mm to 600 mm.

After crushing, material from jaw crusher will be feed to old circuit i.e. to symon cone crusher

via conveyor belt. The plant shall be operated in three shifts to process 0.816 million tonnes of

ROM/ annum. The plant is equipped with dry fog system in the feed hopper, at the screens,

transfer points and at the discharge chutes. There is no change in technology proposed for

mineral processing.

3.9 Resource Optimization/ recycling and reuse envisaged in the project

The used lubricant oils from the Heavy Earth Moving Equipment is collected through a

centralized collection system in the workshop premises and stored in an impervious

underground tank. There are two oil and grease separation pits for separating oil from the

vehicle wash water. Such oil is collected and sold to authorised recyclers approved by Pollution

Control Board. The water from the oil separation pit is again recycled back and reused for

vehicle washing.The old lead acid batteries are also being sold to authorized recyclers approved

by Pollution Control Board.

The mine discharge water is being reused for beneficiation process, dust suppression, A.C.

cooling system and gardening. The water from the tailings dam is also being recycled and

reused for the beneficiation process.The overhead tanks are provided with float valves to arrest

overflow and wastage of drinking water.

Energy efficient lighting system such CFL lamps are being used extensively for lowering power

consumption.

Rain water harvesting system for the colony buildings is proposed to be taken up in future.

3.10 Availability of Water & Energy

a) Power Supply: Presently power load is @2.5 MW. The future power load will be 4 MW,

which would be drawn from the State Grid. Tata Steel has executed necessary agreement

with Grid Corporation of Odisha Limited for supply of 350 KVA of power through WESCO

and same shall be revised to meet the increased power requirement. There is also a Diesel

Generator set of 400 KVA that provide power to plant and office at time of emergency.

b) Water Supply: About 400 KLD of water is the current consumption of Gomardih Dolomite

quarry, which is going to be increased to about 800 KLD. The break-up of the future water

consumption pattern is given below in table 3.7.

3.11(A) Overburden/ Associated Mineral : Elaborated in Para 3.7.(B)

3.11(B) Overburden Dump Management :

The stabilization and rehabilitation activities shall commence soon after the stacks reach the

boundaries of the allotted areas. The stacks of associated minerals shall be developed in the

form of benches not more than 30 m in height. After completion of one bench, a berm of 15 m

width will be left from the sides and then second lift will be made in form of another bench and

so on. The dump slope angle shall be maintained at 28 degree. Afforestation on the slopes will

commence as soon as the first bench reaches the extremities of the lease area. Terraces on the

slopes will be slope inward and 0.5m to 0.75m deep pits will be dug at an interval of 1m x 1.5m.

Saplings will be planted in the pits with a mixture of topsoil and manure/fertilizer at the

beginning of monsoon months. This will bind the associated mineral stack slopes. After

completion of one bench a passage of about 15m width will be left out from the sides and

second lift will be taken in the form of another bench and similar biological reclamation will

be done. In order to prevent the transportation of solids from the slopes, a retaining stone wall

of 0.5m will be constructed 2m away from the toe of such stacks all along the boundary where

ever applicable after studying the topography and drainage pattern. Coir matting shall also done

at places close to roads and other infrastructures.

Afforestation by planting of species of Accacia, Chakunda, Mango,Guava, Litchi, Bamboo,

Lemon grass, Atandi, Arjun, Karanja, Tandi, Hemata, Jatropa, different varieties of grass and

bushy plants etc. on the slope area of the dump

3.11 (C) Hazardous Waste

a) Used Oil: The waste oil generated at various sources is collected in leak proof barrels and

then are kept under a covered roof and on concrete platforms in the barrels very carefully

and sealed properly to avoid any spillage or leakage. The storage area is properly fenced

and caution board displayed. During transfer of waste oil to barrels, a trough is placed

underneath in order to prevent land contamination due to oil spillage. Then at a fixed

interval, these barrels are disposed through auction to the authorized recycler after due

intimation to State Pollution Control Board. After despatch of same, intimation of auction

along with copy of manifest is also being sent to State Pollution Control Board. The same

process shall continue in future also.


24

b) Waste containing Oil: Now we have made an agreement with M/s West Bengal Waste

Management Limited, a division of Ramky Enviro Engineers Limited located at Haldia,

West Bengal to dispose the waste containing oil falling in line with the recent directive

from Member Secretary, State Pollution Control Board, Orissa vide his letter no. IND-IV-

HW-308/9045, dated 01.06.2015. Copy of the Hazardous Waste Authorization granted by

OSPCB is enclosed as Annexure-12.

c) Battery: Battery after being used is given back to authorised recycler.

d) Electronic Waste: All electronic goods are provided by IBM. After completion of their life

IBM take back these electronic goods.

5.0 Planning Brief

5.1 Planning Concept

‘Pucca’ housing within the colony and mining lease has already been provided and there are

still many vacant quarters available. The present infrastructure like road, outbound

transportation, town services shall continue to operate in near future. . No additional manpower

is envisaged in future and town infrastructure will remain same.

5.2 Population Projection

Presently around 59 persons are employed directly by the company at Gomardih Dolomite

Quarry. Around 311 persons are employed indirectly to provide various essential services like

transportation, loading, security etc. A significant proportion of the employees under indirect

employment are attending to their duty from the local villages. No additional manpower is

envisaged in near future. The colony has around 500 quarters including bungalows and flats

out of which around 300 is in good condition. Presently 68 quarters, 3 bungalows and 4 flats

are occupied by company employees and some contractors.

5.3 Land use Planning

There would no significant change in land use pattern as there would be very insignificant

lateral expansion of opencast pits. Besides, the existing infrastructure available for open pit

mining operation would be used during planned period till 31.03.2020. The saturated dumps

shall be reclaimed and rehabilitated through plantation in phased manner.

The Land utilization pattern at present and at the end of the life is given in Table No. 22.

5.4 Assessment of Infrastructure Demand:

As it is an old project running since 1962 and many of the infrastructure exits, no such

significant change in the physical and social infrastructure is being envisaged except the basic

infrastructure for underground mining operation.

5.5 Amenity/ Facility

The existing amenities/ facilities provided to the employees and communities are sufficient in

the present context. However, additional requirement if any shall be provided in future as per

the needs perceived as the project progresses or otherwise statutorily required.

6.0 Proposed Infrastructure

6.1 Industrial Area: The activity involves opencast mining. It is already being carried out within

the acquired area of mining lease creating opencast void and external dumps. The dimension

of the quarry and overburden dumps will further change. Accordingly, the local land use

plan is subject to change. In future, it is proposed to acquire some more area within the

mining lease for the expansion of opencast workings.

6.2 Residential Area: Existing colony outside the Mining Lease area is having more than 300

houses which are sufficient to take care of long-term needs.

6.3 Green Belt: The afforestation will be done in phase manner around the lease area in order

to compensate the loss of vegetation mine and allied activity. It will help in controlling

noise and dust. In addition to this it will reduce the soil erosion as well as it will create

aesthetics beauty. The green belt will be developed in slope of OB dump, vacant area in

lease, around building, garage, and store and along road side.

6.4 Social Infrastructure: The mine has its own pit office, first-aid centre, crèche, canteen, rest

shelters etc. as per the requirement of the Mines Ruls-1955 and MMR-1961. The mine is

connected with the state highway (SH-10) with motorable black topped roads. The

residential colony is established over an area of 8.21 ha, which is beyond the ML area at a

distance of one kilometre from the mine. The mine and the colony both are well equipped

with the basic amenities like drinking water, electricity, etc. Hospital facility is available

within the colony. The maintenance of various equipments are taken care by the

maintenance personnel. All administrative matters related to mine are taken care by

administrative office located near mine and colony. These facilities are satisfactorily

fulfilling the need to employee and local people and it going to remain same.

6.5 Connectivity: Existing facilities will be utilized, which are sufficient during operation. No

alteration is required to divert the routes of the existing transport infrastructure. There are

no ports and/or airports in the vicinity / buffer zone of the proposed expansion.

6.6 Drinking Water Management Present water requirement is 400 KLD. This is met from

rainwater harvested in the mine pit. 800 KLD of water will be required in future for

drinking, dust suppression, green belt development, workshop and other ancillary jobs.

The future requirement of water will be met by drawl of both surface and ground water.

The measure source will be the rain water harvested within the pit. The other source will

be the Nakti Nalla (perennial stream at NW of the mining lease area. The NOC for drawl

of ground water has been obtained from the CGWA. The permission from the State Water

Resources Department is awaited for the drawl of both surface and ground water.

6.7 Sewerage Management: Presently all the sewerage water from colony is accumulating at

shock pit safety tank. However it is proposal to setup sewerage treatment plant.

6.8 Industrial Waste generation: - The Gomardih Dolomite Quarry of M/S TATA STEEL LTD.

has got an authorization from State Pollution Control Board, Orissa by Form-2 having ref.

no. IND-IV- HW-308-9045 to operate a facility for generation, handling, collection, storage

and disposal of hazardous waste till 31.03.2020.


31

6.9 Solid Waste Management: As discussed in chapter 3 in section 3.7

6.10 Power Requirement and supply: Present electrical load is 2.5 MW. In future it will increase

to 4 MW, which would be drawn from state grid. TSL has executed necessary agreement

with Grid Corporation of Odisha Limited for supply of 350 KVA of power through

WESCO and same shall meet the increased power requirement.

7.0 Rehabilitation and Resettlement Plan

Gomardih Dolomite quarry has a surface right over an area of 62.720 ha. The above area was

acquired prior to 1995. The rehabilitation & resettlement issues involved in above area have

already been settled. Going forward, based on the socio-economic survey, R&R Plan shall be

prepared keeping in view the Rehabilitation & Resettlement (R&R) policy of State govt. or

Central govt. whichever is more beneficial to the stakeholders.

8.0 Project Schedule and Cost Estimate

8.1 Time Schedule:

At Gomardih Dolomite Quarry mining and processing plant is well established. In future no

major project and construction is envisaged.

8.2 Estimate of Project Cost:

The Capital cost for Mining mainly aims upon land acquisition for mining and widening of the

Rly. Siding. The Capital cost also includes the cost towards environment management including

toe wall and garland drain making, fixed sprinklers on haul road of permanent in nature,

metalling of permanent haul road, Plantation, Environmental monitoring etc. The operating cost

of Mining, ore processing, product transportation and loading is estimated to be Rs. 335 / MT.

The estimated cost of the project is Rs.27.86 Crores.

9.0 Analysis of Proposal

Steel plants draw major supplies of dolomite for use as a flux and also as a refractory material.

The requirement of low silica dolomite is increasing in steel plants at Bhilai, Rourkela,

Visakhapatnam and Jamshedpur. However, the supply of such materials from indigenous

sources is posing problem. Therefore, Bokaro, Rourkela, Durgapur and Jamshedpur steel plants

are drawing supplies of low silica dolomite from Bhutan for use in tar-bonded refractory bricks

required for lining of LD furnaces and also for flux purposes. Gomardih Dolomite Quarry is

presently producing Dolomite at a rate 0.48 MTPA. In future is planned to enhance its

production up to 0.816 MTPA. So it can reduce demand supply gap of dolomite in Indian Steel

Industry. Along with this it will increase the revenue in terms of taxes at local, State and

National level. Moreover it will create direct and indirect employment opportunities.

Tata Steel is also actively involved in corporate social responsibility like industrial training of

local youths, development of local infrastructures and helping people in self-employment.
