2.1. Identification of Project and Project proponent

The Gare Palma Sector - II Coal Block lies in the eastern part of the Mand-Raigarh

coalfield inChhattisgarh state. Ministry of Coal, Govt. of India, has allotted this coal block

to Maharashtra State Power Generation Company Limited (MSPGCL) for their captive

consumption in their end use power plants.The block is fully explored but non-producing

one.

Gare Palma Sector - II Coal block was earlier allocated by Ministry of Coal jointly to Tamil

Nadu Electricity Board (TNEB) and Maharashtra State Mining Corporation Limited

(MSMC) on 2nd

August, 2008 under the Government dispensation route. TNEB and MSMC

formed a joint venture company by name “Maha Tamil Colliries Limited”.

The Supreme Court of India, vide its judgment dated 25th

August, 2014 read along with its

order dated September 24, 2014 had cancelled allotment of 204 coal blocks. Subsequent

to the Supreme Court Judgment, the Coal Mines (Special Provisions) Ordinance dated

24th

September, 2014 read with Coal Mines (Special Provision) Second Ordinance, 2014

were promulgated and the Coal Mines (Special Provisions) Rules, 2014 were framed for

auction and allotment of all blocks which were subject to cancellation pursuant to the

Supreme Court Judgment. The Gare Palma Sector - II Coal Mine also appeared in the list

of 204 coal blocks and accordingly, its allotment to the prior allottee namely “MahaTamil

Collieries Limited” was cancelled pursuant to Hon’ble Supreme Court’s Judgment.

Maharashtra State Power Generation Co Ltd. (hereinafter referred to as “The

Company”) has been incorporated under Indian Companies Act 1956 pursuant to

decision of Govt. of Maharashtra to reorganize Erstwhile Maharashtra State Electricity

Board (herein after referred to as “MSEB”). The said reorganization of the MSEB has been

done by Govt. of Maharashtra pursuant to Part XIII read with section 131 of The

Electricity Act 2003. Mahagenco has been incorporated on 31.5.2005 with The Registrar

of Companies, Maharashtra, and Mumbai and has obtained Certificate of

3.3. Details of alternative sites

The mining project is site specific project as it is related to occurance of Coal. Hence no

alternative sites were studied for purpose.

3.4. Size or Magnitude of Operation

The maximum coal production capacity of the proposed mine is 23.6 MTPA (OC - 22.0

MTPA + UG - 1.6 MTPA) with peak capacity of OC will be 23.6 MTPA before the UG

becomes operational. The mining operations have beenplanned to be started from rise

side (NW side) and to advance towards dipside (south side) and towards eastern side.

The block is surrounded by coal bearing areas on east and south direction.The strategy is

to divide the block into two parts along Kelo river. The twoparts are planned to be mined

in sequence by dovetailing. The western partwhich contains larger reserve will be mined

first by opening at the northwesternportion and advancing the operations towards dip

side (south side)and towards eastern side. It has been assumed that the mining

operations in the block will be started after rehabilitating the villages to the extent

required with time as well as getting the forestry clearance.

3.5. Project Discription and Project Details

Net geological reserves of coal as per Geological Report (GR) are 1059.29 MT comprising

of 736.10 MT (having thickness more than 0.5m proposed for OC mining down upto

seam-VI) and 323.19 MT (having thickness morethan 0.9m proposed for UG mining

below seam-VI). These reserves have been cross checked by Min Mec (RQP) and have

been found in order.

3.5.1 Sequence of Opencast mining

The development works during the first year include making access road to sites of

mining activities, removing and rehabilitating the villages lying over the parts of the

block, obtaining 1st

set of mining equipment, diversion of local roads, top-soil removal,

driving box-cut and taking up other constructionactivities. The mode of transporting the

coal to TPP will be through rail fromthe nearest available siding.



The mining will begin with an aim of producing 11.80 MTPA from 5th

year and peak

capacity of 23.6 MTPA by 7th

year onwards from Open cast. The total coal production in

the first five years will be 20.30 MT. However, the productionfrom OC will be reduced

from 12th

year onwards with the onset of UG miningoperations such that the total

production from the mine is continued at 23.6MTPA matching with the requirements of

end use plants. The UG mine isproposed to achieve a peak capacity of 1.6 MT of coal

from the 15th

year onwards. Accordingly the production from the OC will be kept steady

at 22 MTPA from 15th

year onwards.

Year 1

The initial mine entry (haul road) will be aligned along SE direction for a distance of

about250m along the Inclines safety barrier after which it will reach 280 mRL at a

gradient of 1:16. The lowest bench to be worked in the 1st

year is 270 mRL which will be

approached by a ramp from 280 mRL bench.The depth of pit will be 10 m to 30 m which

will be worked in 1 to 3 benches.

Coal production during this year will be 0.25 MT. The corresponding OB (5 Mcum) will be

disposed off in Surface Dump over the coal bearing area (to be rehandaled later) in the

dip side of the West Pit. There will be no backfilling activities in this year and no activity

related to UG mining.

2nd

to 3rd

Year

The working benches will be advanced parallel to the already existing benches. The

length of the haul road will become 1072m along the safetybarrier of the incline landing

at 230 mRL. The lowermost levels will go downto about 215 mRL which will be

approached by ramps on the benches. Themining operations will reach the seam IX floor

during the 3rd

year.

Coalproduced in two years will be 4.55 MT @ 1.55 MT and 3.00 MT per yearrespectively

during 2nd

and 3rd

year. The related OB amounting to 44.10 M.Cum (14.10 M.Cum during

2nd

and 30.00 M.Cum during 3rd

year will be disposed of in Surface Dump in the dip side

over the coal bearing area ofWest Pit as during previous year. A maximum depth of

about 82m will beachieved by the end of the 3rd

year. There will be no activity related to

UG mining or coal production in this year.

4th

to 5th

Year

The working benches will be advanced parallel to the already existing benches in the

previous year. The length of the haul road will become 1558 m which will approach the

floor of the Seam VIII having exposed floor from 205 mRL to 230 mRL.



Coal produced in two years will be 15.50 MT @6.00 MT in 4th

year and 9.50 MT in 5th

year

respectively. The related OB (45 Mcum and 80.00 Mcum) will be disposed of in Surface

Dump proposed tobe located over the coal bearing area (to be rehandaled later) at a

distance of over 500 m from the uppermost bench. The area required for stacking top soil

will be 60 Ha for restricting the height to 6 m and the provision of 60 Ha has accordingly

been made beyond the surface dump. There will be noactivity related to UG mining or

coal production in this year.

6th

to 15th

Year.

The working benches will be advanced parallel to the already existing benches in the

previous years. The SW corner of the advancing working benches will just abut against

the batter of Kelo river.

Thus Coal produced in ten years (6th

to 15th

) will be 229.7 MT. The related OB willbe

disposed of in Surface Dump during a part of the 6th

year (47.07 M.Cum) after which total

OB will be accommodated within the backfill of the West Pit. As the decoaled area on the

northern side of the West Pit will berequired for backfilling the haul road will be shifted

and aligned just alongthe NE batter with its entry mouth located just at the SE end of the

inclinesafety barrier. The mouth will be located at 288 mRL. By the end of the 15th

year,

the length of the haul road will be 3.45 Km and it will reach thelowermost seam VI,

mineable by OC method.

The whole surface dump constructed during the 1st

6 years will be rehandaled and

backfilled into the void during the period from 7th

year and20th

year (both years

including).

16th

to 25th

Year.

The West Pit will be further advanced towards south direction till they abut against the

boundary of the West Pit of the block along the Kelo river. The East Pit will also be

opened from 20th

year.Therefore the coal production and OB generation will take place

from West Pit as well as from East pit from 20th

year onwards. All the OB generated from

West as well as East Pit will be backfilled into the West Pit decoaled area concurrent with

mining. The backfill area will advance upto and abutagainst the NW end batter of the

West Pit by the end of 25th

year. A 100 m high crown dump will have to be created above

the backfill area of West Pitto accommodate the OB generated in the past as will become

surplus from the backfill. The coal extracted upto the end of 25th

year will be 470 MT and

OB generated as 2463.1 MCum from both the pits.

26th

Year to End of OC Mining.

West Pit will finish in 26.5 years keeping intact the shaft pillar near the Kelo river as well

as the area under safety pillars of inclines and facilities located in the northern portion of

the West block.These areas will be mined after the mining of eastern part of the



blockduring the following years and will be retained till the coal from UG mining in the

western part is exhausted.

The total OB produced from both the Pits will be 2761.1 M.Cum (B) includingTop Soil

(14.64 MCum Bank or 16.84 MCum Loose). The TS will be accommodated over the dip

side coal bearing area of West Pit upto 15th

year end after which whatever TS will be

required to be preserves, it will bestacked over the backfilled area. The height of the TS

stack will be restricted to 6 m. Most of the area 2280.17 Ha in the post mineclosure stage

will be converted into an agriculture area.

3.5.2 Sequence of Underground Mining

Entries for underground mining

Two Inclines (one pair) having cross-section 4.8m x 3m and 2 shafts (Exhaust shaft-1 with

6m dia and Intake shaft-2 with 5m dia), all from surface to the lowermost seam-I

Combined are planned to be located in the NW portion of the western part of block. As

the two inclines are notadequate to supply the intake air to sustain the proposed 1.60

MTPA production, an additional Shaft-2 (dia 5m) as mentioned above, is proposed near

the inclines which can also be equipped with men/materials windingfacilities if required.

Both the inclines are started from a point located at 100m distance from theNW

boundary line of the block. The surface RL at the mouth of inclines will be 299 m AMSL

and the inclines will be driven at a gradient of 1:4.5 parallelto the NE block boundary at a

distance of 100m and 150m respectively.That means that the inclines will be 50m apart.

Coal Production

The production from one continuous miner will be 0.4 MTPA. There will be four

continuous miners will be operational at any time with following capacity. The main

drives in coal connecting to inclines, shafts as well as all dip drives will be also driven with

continuous miners. All the workable seamswill be developed and depillared with

continuous miners along with two shuttle cars in each set of continuous miner.

Accordingly, this mining plan has proposed 1.60 MTPA production from underground

mining which could be easily achieved.

3.6. Availability of water its source, Energy/ Power Requirementand Source

3.6.1 Water Source

The total water requirement will be 1995 cum/day. The requirement of water for dust

suppression, plantation,dump trucks washing workshop etc. is estimated to be about

1546 cum/day.The requirement of potable water for other site services i.e. Canteen,

Restshelter, Offices is estimated at about 1239 cum/day out of which 790 cum/day will

be reclaimed from the STP of colony.

The total water requirement will be met by bore-wells at site during the initial2-3 years

after which the mine water will be used after appropriatetreatment as required.



3.6.2 Energy/Power Source

The power will be fed to the project by a 11 KV overhead line from theexisting grid sub-

station at Tamnar.

3.7. Quantity of Wastes Generated (Liquid and Solid) and Scheme for their

Management /Disposal

Overburden consists predominantly sandstone with minor amount of

shale,carbonaceous shale, ungraded coal and thin coal bands (<1m in thickness).

There is only one surface dump proposed which will be located over the coal bearing

area in the southern portion of the West pit area. This dump will be spread over a

maximum area of 380 Ha (5th

year) and willaccommodate 218.81 MCum (B) OB waste.

The Dumping will start from 1st

year and continue upto 6th

year, however the exclusive

dumping into thissurface dump will be upto 5th

year after which part (47.07) of the OB

will bebackfilled in 6th

year.

The full height of the dump will be 90 m in 6th

year. No OB will be required to be disposed

over the surface dump after 6th

year.Backfilling will start from 6th

year of the project

operation with a quantity of 87.07 MCum (B). During 6th

year partial backfilling will be

done and then upto final year full backfilling will take place concurrent with mining.

The total topsoil generated will be 14.64 MCum (B) during the life of themine. Unutilised

part of the same will be stacked separately in a soil stackpile located beyond the surface

dump over the coal bearing area withinWest Pit area of 60.00 Ha (max). It will be used for

growing plants along the fringes of the site roads and reclamation of surface dump and

backfilled area.The top soil stockpile will be low height not exceeding 6 m and will

begrassed to retain fertility. Besides this, there would be temporary stacksnear the

excavation area and area to be reclaimed which will be made useof for concurrent filling

interspersed with broad valleys. The general elevation of the ground ranges from 242 m

to 303 m above MSL. The slope is towards south. The hills are relict type and rise about

450 m above MSL. The southerly flowing perennial Mand River with its tributaries

constitute the main drainage of the area. The Kelo River, a tributary of Mahanadi, drains

the eastern part of the coal block.

The topography of Gare Palma Sector II is mostly covered by softer horizon and more

resistant sedimentary rocks stand out as ridges, rising as high as 580 m above MSL

(SilotPahar) in the north west and 600 m above MSL (MorgaPahar) in the north east. The

general ground elevation of the sector II area under investigation varies between 240 m

and 300 m above MSL. The minimum ground level is <246 mRL in the region north of

borehole MMT-131, located in the southern -eastern part of the block and maximum

ground elevation is 304.15 mRL at triangulation station T1/T1. The block exhibits

undulating topography. Kelo River flows from north to south through the south eastern

part of the block. A few ponds are present within the block.

Government Forest Land *75.94

Grand Total 2583.48

Note: *75.94 Ha of Protected Forest land and 135.37 Ha of Revenue Forest land is

present within the mine lease area, which needs to be diverted for mining purpose after

obtaining forestry clearance from the Ministry of Environment and Forest, Govt. of India

under the Forest (Conservation) Act 1980.

4.4. Existing Infrastructure

The proposed lease area is a virgin block and no mining has been undertaken so far. The

various temporary site services proposed to be constructed will be:

1. Office

2. Store

3. Workshop

4. Water Tank

5. First-Aid Center

6. Rest Shelters etc.,



4.5. Soil Clasification

Soil formation is mainly related to the parent rock material, surface relief, climate and

natural vegetation, animals, insects and man also play an important role in soil

formation. A major part of the block is covered by a thin layer of soil and alluvium

horizon. The weathering has affected all the strata below soil to varying extent. The

thickness of soil ranges from 0.50m to 15.00m. The entire area of Gare Palma sector-II

Coal Block is mostly covered with soil and at a few places only, outcrops of sandstone &

shale can be seen. The soil is silty clay in texture and red to pale brown in color.

4.6. Meterological Data

4.6.1. Climate

The climate of the study area is of subtropical type, and characterised byan oppressive

hot summer, a mild winter and well distributed rainfall duringthe south western

monsoon season. The year may be divided into fourseasons. The summer season lasts

from March to the middle of June, andthe period from June to September is the south

west monsoon season. October and November constitute the post monsoon season and

the coldseason is from December to February. The nearest meteorological stationof IMD

is at Raigarh.

4.6.2 Temperature

As per the monthly average of daily maximum and minimum temperatures for the period

1996 to 2005, collected from IMD Station, Raigarh, themonthly mean of minimum

temperatures ranges from 12.04°C in January to27.57°C in May. The monthly mean of

maximum temperature ranges from27.56°C in January to 42.08°C in May.

4.6.3 Rainfall

The rainfall does not show any cyclic occurrences and shows wide anderratic variations,

ranging from as low as 144.9 mm in 2004 to 1852.4 mm in2003. The average annual

rainfall for the period 1996 to 2005 was 1216.4mm. The monsoon season is spread over

the months from June toSeptember. However, the total rainfall as per IMD Raigarh is

1429.3 mm.

4.6.4 Wind Velocity and Wind Direction

The wind speed and direction for long term period from 1970-2000 havebeen studied

through the Windrose diagrams supplied by IMD, Raigarh, for8.30 hrs and 17.30 hrs

respectively. An observation of the morningWindrose shows that the predominant wind

direction is from NE between (October to April) and SW betweenMay to September.

As per the evening Windrose, the predominant wind direction is from NEbetween

October and January, NW between February to May and SWbetween June to September.

The general wind speed ranges form 1 to 5Kmphthroughout the year. However winds in

the speed ranging from 6-11Kmph and 12-19 Kmph also occur.



4.6.5 Relative humidity

The relative humidity varies from 22% in (April) to 78% (August) duringevening and 39%

(April) to 84 % (August) during morning.

4.7. Social Infrastructure Available

Raigarh- 26.22 Km (SW) is having all facilities like Police station, Fire station Hospital,

Bank, Post Office, School, Workshops etc.

5. Planning Brief

5.1. Planning Concept

While Considering, the available reserves, seam disposition, depth, availablestrike length

for opencast mining and feasibility to deploy large sizeequipment in opencast operation,

feasibility of simultaneous undergroundoperation, the optimum capacity of the mine has

been estimated at 23.6 MTPA. Hence the mine has been planned for a targeted

production of 23.6MTPA, out of which 22.0 MTPA (23 MTPA prior to start of UG

Operation) would come through opencast operation and 1.6 MTPA throughunderground.

It may be worthwhile to mention here that the earlier allotee ofthe coal block had also

submitted a mining plan to MOC in which the RQP had assessed the capacity as 23.6

MTPA as above.

Considering the simultaneous operation of OC and UG and that a lag is tobe maintained

for UG working, the target capacity through UG has beenfixed at 1.6 MTPA. The targeted

production through UG mining may bereviewed after 25 years with a view to increase the

production andproductivity based on the then available technology.

As per the practice in vogue for OC mine planning, the minimum coal seamthickness for

mining is adopted as 1m. However, in this specific case ahuge quantity of reserve (53.536

MT) falls in a thickness range between0.5m-0.9m. Giving due consideration to

conservation of resource, The RQP has calculated the Opencastable reserves by assuming

minimum miningseam thickness of upto 0.5m irrespective of the fact that mining of

suchthickness will require extra efforts as well as lower efficiency of equipment.However

the reserves mineable by underground method have beenassumed as upto a minimum

thickness of 1.5m, though the reserves oflower thicknesses have been mentioned

alongside.

The overall reconciliation of reserves in the block is as given in Table 5.1

5.2. Population Projection

Due to proposed project around 3400 persons will be in the mining activity, they will be

mostly from nearby villages, only few people will be accommodated at the site such as

security persons and emergency staff in rest shelter.

5.3. Land Use Planning

The total land area of the block is required for Mining Lease. Therequirement for

additional land required for mining purpose for approachroad to the block and approach

to railway siding etc. will be assessed afterfinalisation of railway alignment passing

through Gare Palma Coalfield andconsidering limited availability of land, as the block is

surrounded by othercoal blocks. The colony will be located away from the block non

coalbearing area to be identified in consultation with local authorities. The ‘during-

mining’ stage land use is given in Table 5.2.

5.4. Assessment of Infrastructure Demand

It is obvious to have some of the essential infrastructures to facilitate the employees. For

this purpose it is planned to have office, store, first-aid center, rest shelter etc...

5.5. Amenities/ Facilities

All infrastructure facilities such as education, health facilities and other social facilities

are available at district headquarter due to which the proposed site is facilitated with

adequacy in amenities. As most of the workers are employed from the surrounding

villages, they would be using available medical facilities in the nearest primary health

center.

6. Proposed Infrastructure

6.1. Industrial Area

It is proposed to establish the temporary structures statutory building having the

facilities like Office, first aid center and rest shelter.

6.2. Residential Area

It is proposed to establish only some essential quarters (50% of the employees) within

the mine lease for the Mine Personnel to cater to essential services. Remaining persons

will be accommodated at a suitable site outside the mine lease area.

6.3. Green Belt

Total Unsued land area is 36.07 Ha which would be used for Plantation/Afforestation/

Future expansion.

The species going to be planted would be local species as these are having a better

chance of survival in this region.

6.4. Social Infrastructure

This Project is providing employment to local people directly and indirectly. Indirect

employers are shopkeepers, mechanic, drivers, transporters etc. The lessee will

responsible for providing better social infrastructure benefits such as drinking water,

health care measures, educational facilities, promotion of culture and religious activities

in surroundings.

6.5. Connectivity (Traffic and transportation Road/Rail/Metro/Water ways etc)

6.6. Water Management

1995 m3/day water will be required for the mine, residential colony after considering the

reuse of 80% of water reclaimed from colony STP. The water requirement during initial 3

years for construction and of mine operation is proposed to be sourced from Kelo River

or Bore Well.Subsequently after 3 years onwards Industrial water from mine sump and

settling pond would be used till the end of life of the mine.

Groundwater will be utilized for drinking purposes. The same will be drawn from the

bore wells. Detailed hydro geological studies will be carried out to assess the availability

of requisite water for mine operation.

6.7. Sewerage System

Mine discharge: Mine effluent contains silt and coal particles, which will be treated in

two stages at primary sedimentation sump in mine floor and secondary sedimentation

sump at mine surface.The mine discharge, will be used to meet the requirement of

afforestation/plantation, dust suppression, firefighting, and other industrial, domestic

applications. Surplus water meeting the prescribed standards, if any, will be discharged

into nearby surface body.

Washery effluent: Waste water will be collected in slime ponds and circulated back into

the process. Zero effluent discharge will be practiced

Workshop effluent: The workshop effluent will be treated in a proper effluent treatment

plant. Oil and grease will be skimmed using oil trap and stored in leak proof containers

and will be sold to authorized vendors.

Domestic effluent: STP will be provided. Sludge after digestion will be used as manure /

compost.

6.8. Solid Waste Management

Mining waste will be dumped on non-coal bearing area as external dump and rest will be

backfilled as per Mining Plan. Retention wall of adequate dimensions will be constructed

at the base of external dumps. Garland drain and check dam will be made. Proper overall

slope angle will be maintained. Dumps will be gradually reclaimed and rehabilitated using

suitable plant species and grasses.



6.9. Energy/Power Source

The power will be fed to the project by 11 KV overhead lines from theexisting grid sub-

station at Tamnar.

7. Rehabilitation and Resettlement (R & R) Plan

9 Analysis of Proposal

9.1 Socio-economic Benefits

As there will be displacement of 1679 families in all fourteen villages, a rehabilitation

programme is required. However, the land and home or bothoustees will be given

rehabilitation and resettlement benefits according tothe Govt. of Chhattisgarh Policies

and prevailing practice in industries in thevicinity. The detailed R&R plan is under

preparation. In addition to theprovisions of the CG R&R Policy 2007, as the proportion of

tribal familiesamong the land losers is significant and in view of project area falling

underscheduled V, a separate Tribal Development Plan (TDP) is essential forvulnerable

group. The company is in the process of making a Tribal Development Plan containing the

profile of community, livelihood pattern, aneed assessment for community development

and a specificcommunication program to engage with the community. The survey is

being done by Asian Institute of Sustainable Development Ranchi (Jharkhand).

The employment will be provided as per the provisions of the Policy of Govt.of

Chhattisgarh. Advisory Committee will be formed by Collector/ RevenueDivisional

Commissioner. The development in the area which ispredominantly backward, will

largely benefit the local population. Preferencewill be given to the local people for gainful

employment in the unskilled and semi-skilled categories as and when the need arises.

Similarly, Due to development activity in the rural and backward area, traders and private

enterprises will grow also in the region, which will provide indirectemployment to the

many local people. The company will arrange medical camps, sports competitions and

awareness programmes for the benefit of local population.
