1.0 INTRODUCTION

1.1 BACKGROUND OF PROJECT REPORT

The Amalgamated Gondegaon-Ghatrohan OC project had been envisaged in Gondegaon-Ghatrohan block in Kamptee Coalfield. The project consists of two sub quarries i.e. Gondegaon sub quarry & Ghatrohan sub quarry. Presently, both the sub-quarries are in operation by departmental HEMM (in Gondegaon sub-quarry) as well as Out-sourced HEMM (in Ghatrohan sub- quarry).

PR for Gondegaon OC was prepared in November, 1989 for a capital investment of Rs.6796.25 lakhs and target production of 0.75 Mty and was approved in the year 1992 in Departmental Option.

Excavation work of Gondegaon OC was started in 1994-95 and coal extraction commenced in 1995-96. Due to increase in the expenses by 40.67%, a Revised Cost Estimate was prepared for 0.75 Mty in June, 1998 for a total capital investment of Rs.9560.24 lakhs (existing capital of Rs.6151.95 lakhs + balance expenditure of Rs.3408.29 lakhs). The RCE was approved by CIL Board on 25.8.1998 for a capital investment of Rs.9560.24 lakhs.

A Completion Report for Gondegaon OC mine was prepared by WCL in 1999 for a total capital expenditure of Rs.9535.31 lakhs.

Subsequently, PR for Gondegaon Extension OC including Ghatrohan OC was prepared in June, 2004 for a capital investment of Rs.12415.67 lakhs (Gross Block) for a capacity of 1.50 Mty. However, it was sanctioned for incremental capacity of 0.75 Mty with an incremental capital of Rs.2753.71 lakhs.

Thereafter RPR for Amalgamated Gondegaon-Ghatrohan OC (December- 2010) was prepared to enhance the production capacity from 1.50 Mty to 2.00 Page - 1 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) Mty. The balance coal reserves and volume of OB calculated as on 01.4.2010 were 29.07 Mt and 153.91 Mm3 respectively at a stripping ratio of 5.29 m3/t. This RPR was accorded 2nd Stage approval by WCL Board on 07/01/2011 with an additional capital investment of Rs 73.8846 crores in Partial Hiring option.

As desired by WCL, updation of the approved RPR (Dec. 2010) was done at August 2015 prices and discussed in the TSC meeting at WCL HQ on 11/09/2015 wherein it was directed to review report for a higher capacity on the basis of joint technical meeting between CMPDI, WCL HQ, WCL Nagpur Area & mine officials. Subsequently, a meeting was held on 12/9/2015 at CMPDI, Nagpur and it was decided to prepare Revised Project Report of Amalgamated Gondegaon - Ghatrohan OC for a target capacity of 2.50 Mty.

Based on the decisions taken in various meetings with WCL (HQ), Nagpur Area and mine officials, Revised Project Report of Amalgamated Gondegaon Ghatrohan OC for 2.50 Mty capacity was prepared in November, 2015 considering the latest scenario of land acquisition and further project requirements communicated by Mine/Area.

The Revised Project Report of Amalgamated Gondegaon Ghatrohan OC (2.50 Mty) was approved by WCL Board in its 273rd meeting held on 3rd February, 2016.

GM (P&P), WCL vide his letter no. WCL/GM (P&P) / MR / 18/484 dated 09.02.2018 requested CMPDI, RI-IV, Nagpur to update the RPR of Amalgamated Gondegaon Ghatrohan OC for 3.50 Mty capacity.

Based on the decisions taken in various meetings with WCL (HQ), Nagpur Area and mine officials, following changes were incorporated in the RPR of Amalgamated Gondegaon Ghatrohan OC updated in the month of February- 2018 :

a) Target capacity of the mine was increased from 2.50 Mty to 3.50 Mty and accordingly life of mine reduced to 7 years as on 01.04.2018.

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019)

b) Additional Provision was made for 1 no. of Mobile Crusher on hiring and Electronic Weighbridge to cater the increased capacity of the mine.

c) Provision of Manpower was increased to 921 considering an increase of 201 manpower over & above the present day manpower of 720 .

d) Provisions for P&M revised considering correspondence with WCL.

e) Provisions for HEMM was revised considering existing HEMM at Gondegaon Ghatrohan OC.

After incorporating the above, the RPR of Gondegaon Ghatrohan OC mine was updated for the month of February-2018. The above RPR was discussed in the meeting of Technical Sub-Committee of WCL Board held on 07.03.2018 at WCL (HQ), Nagpur. In the meeting, it was discussed that there is wide difference in the quality of upper set of coal seams (Seam-V and IV) and lower set of coal seams (Seam-III & II) in Amalgamated Gondegaon Ghatrohan OC mine. Finally, it was decided that separate coal stocks and dispatch arrangement for inferior quality coal of upper seams (V and IV) and better quality coal of lower seams (Seam-III & II) will be maintained in the mine and accordingly, sale price of both type of coal will be considered separately as per their corresponding year-wise quantity in economic evaluation.

Based on the above decision, RPR of Amalgamated Gondegaon Ghatrohan OC mine was prepared in the month of March, 2018.

Hence, for applying for amendment in the existing EC of Expansion of Gondegaon Extension OC, a Mining Plan with mine lease area of 791.40 ha (845.74-54.34) for a capacity of 3.50 MTPA has been prepared.

1.2 EXISTING STATUS

Five coal seams which are characteristic of Kamptee Coalfield, are present in the Gondegaon-Ghatrohan block also. All these seams occur in the Middle Barakar horizon of about 100 m thickness. The seams in Kamptee Coalfield are numbered from bottom to top, the bottom-most Seam-I is the oldest, while the top most Seam-V is the youngest. The oldest Seam-I is found to be deposited around 100 m above the Talchir-Barakar contact. Of the five seams, Seams-II, III & IV occur in 2 to 3 split sections, while Seam-V is present as a single horizon. Seam-I is impersistent and also thin, mostly below 0.90 m thickness, hence not considered in this report.

Due to the steep gradient & multi-seam characteristics, shovel-dumper system of mining is in vogue.

Seam - II to V occur in Gondegaon-Ghatrohan Block in nine sections, viz. Seam-I (Bottom), I (Top), II (Bottom), II (Top), III (Bottom), III (Top), IV (Bottom) {Seam-IV Bottom and IV Middle may be considered as Seam-IV Bottom due to very thin parting between them}, IV (Top) & V.

The various performance parameters of the mine from 2012-13 to 2016-17 as per cost sheet are as follows:-

1.3 JUSTIFICATION OF PREPARATION OF MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE

The RPR for Amalgamated Inder-Kamptee Deep OC which was approved by WCL Board in September,2018 in which 54.34 ha land was proposed to be transferred from neighbouring Gondegaon-Ghatrohan OC. Accordingly, EC application for amendment in EC of Expansion of Kamptee Deep OC for a capacity of 3.20 MTPA within a mine lease area of 857.60 ha was discussed in EAC in its 46th meeting held on 25.06.2019. The EAC, after deliberation observed that the proposed amalgamation involves carving out some area of adjoining Gondegaon Opencast coal mining project and thus requiring amendment in its environmental clearance also. There being no proposal in this regard, the committee was not inclined to take the proposal forward.

Hence, for applying for amendment in the existing EC of Expansion of Gondegaon Extension OC, proposed mining plan with mine lease area of 791.40 (845.74-54.34) ha for a capacity of 3.50 MTPA has been prepared.

Page - 11 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) from Western as well as Southern part of country. The justification of this mine has been studied in the light of estimated demand for non-coking coal from power sector in Maharashtra and production forecast from existing, completed, ongoing and future projects of WCL.

2.5 AVAILABLE LINKAGE OR FIRM FUEL SUPPLY AGREEMENT (FSA)

At present there is no firm fuel supply linkage specific for this mine. However, as detailed in para 2.1 above, existing commitments through FSAs and MOUs is available for WCL as a whole.

2.6 JUSTIFICATION AND MARKETABILITY

From the tables given in para no. 2.1 to 2.3, it is clear that the deficit in supply of coal from WCL is 34.272 Mt in 2019-20 which will be narrowed down to 27.849 Mt in 2020-21 and 23.502 in 2021-22, if WCL achieves the target capacity of 60 Mt in 2020-21. To further reduce the gap between demand and supply of coal, it is very essential to either open new mines or increase the production from existing mines of WCL. Thus, Mining Plan of Expansion of Gondegaon Extension Opencast Project having target capacity of 3.50 Mty will help to reduce the gap between demand and supply of coal from WCL mines.

The surface area is generally undulating with elevations ranging from 278 m to 288 m above MSL. The main drainage is controlled by Southerly flowing Kanhan river along the Western and Southern boundaries of the block. Minor seasonal streams originating within the block drain into Kanhan river. In general the area is sloping towards South West and South.

3.3 LAND USE PATTERN

The entire area of the block is covered by fertile black cotton agricultural land and is presently being used for growing crops like cotton, lentils, chilli, sunflower etc.

4.0 GEOLOGY

4.1 INTRODUCTION

CMPDIL prepared a comprehensive report incorporating the data of 76 boreholes drilled by IBM & 7 boreholes drilled by CMPDIL. The report entitled "Revised Geological Report on Ghatrohan-Gondegaon Block, Kamptee Coalfield" was submitted in March, 1985 by CMPDIL wherein the entire data was re-interpreted with the purpose of evolving a simplified structure and estimation of reserves upto 150 m depth for Seams-V & IV. This was done so as to facilitate opencast mine proposition in the block.

In March 1986, CMPDIL vide their letter no.RIN:GD:MECL:6851 dated 6th March, 1986, requested Mineral exploration Corporation Limited (MECL) to take up ten points for drilling in Gondegaon-Ghatrohan block. The boreholes were proposed upto Seam-IV Bottom only.

The exploration in the block commenced in April'86. While the exploration was in progress, on reviewing the data of the six boreholes completed by MECL, further programme to take up additional boreholes was finalized in different stages. Thus, in this block, a total of 44 boreholes were released out of which only 33 boreholes could be completed by MECL.

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019)

Though the boreholes were initially proposed to be drilled upto Seam-IV Bottom so as to assess, in particular, the quarriable potential, some of the boreholes were advised to be drilled upto the bottom-most of Seam-I in the Kamptee Coalfield. This was done in order to confirm the thicknesses and quality of the seams – III, II and I.

MECL submitted the report entitled "Geological Report on Exploration for Coal Gondegaon-Ghatrohan Block, Kamptee Coalfield, April' 1988".

To increase the coal production from Nagpur Area of WCL, opencast patch deposits in Gondegaon-Ghatrohan block were identified and CMPDIL, RI-IV, Nagpur published a project report entitled "Opencast patch deposits in Ghatrohan block", March 1996. In the above report, drilling for confirmation of Incrop, Structure and workable thickness of lower seams were suggested. CMPDIL, RI-IV took the exploration work during May,1996 to June,1996 and February, 1997 to June,1997 in two phases and drilled total 31 no. of boreholes (CMKG Series) with 2973.00 meters of drilling. CMPDIL prepared a report entitled "Geological Note on Part of Gondegaon-Ghatrohan Block, Kamptee Coalfield, Dist. Nagpur, (M.S.), March,1998".

4.3 GEOLOGY AND STRUCTURE OF THE BLOCK

4.3.1 Geological Formations

The formation-wise description is as follows :-

Page - 15 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019)

Talchirs

There are no outcrops of Talchirs in the block. Borehole MKG-29, drilled in the north-eastern part of the block, has intersected Talchirs at 119.53 m. Its thickness, as intersected in the borehole, is only 1.47 m and could be identified because of its distinct greenish coloured shale.

Barakars

Barakars are of Lower Permian age. Barakars in the block could be divided into three parts, based on the presence or absence of seams. The three parts of Barakars are Upper Barakars, Middle Barakars and Lower Barakars.

Upper Barakars

The Upper Barakars is that part which lies above the youngest Seam-V. It consists of medium to coarse grained grey sandstones.

Middle Barakars

The horizon from roof of Seam-V to the floor of Seam-I is termed as Middle Barakars. The Middle Barakars comprises of grey feldspathic sandstones, shales, carbonaceous shales and 5 seams with their individual thickness of 1 m to 10 m.

Lower Barakars

The part of Barakars lying below floor of Seam-I upto the Talchir contact is termed as Lower Barakars. It comprises mainly fine grained sandstone, shales and intercalations. It is characterized by the presence of fine garnets in dissiminated form.

Kamthis

Kamthis have been deposited on the eroded surface of Barakars and thus, there is a distinct erosional unconformity between them. Kamthis, in general, comprises friable ferruginous sandstone which is medium to coarse grained and pink in colour. It also consists of shales and variegated clays.

The area in its major central and western parts is covered with black cotton soil. In the west and in south, along the banks of Kanhan river, the alluvium in the form of sand and gravel has been noticed.

4.3.2 Faults

The block is traversed by eleven faults serially numbered as F1 to F11. The faults have been interpreted based on the difference in FRL on both sides, omission and reduction in seam thickness, etc. The description of individual faults is furnished in the following table:-

4.3.3 Strike and Dip

The strike and dip of the coal seam in the proposed area is entirely based on the sub-surface data obtained from the boreholes. The floor contours of the composite seam has been drawn at 10 m interval from which it would be seen that the amount of dip and strike direction are quite variable.

The Gondegaon-Ghatrohan Block is a part of the Kamptee - Silewara- Patansaongi Sub-basin. The general strike of beds is ESE-WNW to NW-SE. The gradient of the coal seams varies from 1 in 3.5 to 1 in 5 due SW to SSW.

4.4 COAL SEAM

Five coal seams which are characteristic of Kamptee Coalfield, are present in the Gondegaon-Ghatrohan block also. All these seams occur in the Middle Barakar horizon of about 100 m thickness. The seams in Kamptee Coalfield are numbered from bottom to top, the bottom-most Seam-I is the oldest, while the Seam-V, the youngest. The oldest Seam-I is found to be deposited around 100 m above the Talchir-Barakar contact. Of the five seams, Seams-II, III & IV occur in 2 to 3 split sections, while Seam-V is present as a single horizon. Seam-I is impersistent and also thin, mostly below 0.90 m thickness.

Seam-I to V occur in Gondegaon-Ghatrohan Block in nine sections, viz. Seam-I (Bottom), I (Top), II (Bottom), II (Top), III (Bottom), III (Top), IV (Bottom) {Seam-IV Bottom and IV Middle may be considered as Seam-IV Bottom due to very thin parting between them}, IV (Top) & V.

5.2 MINEABLE RESERVES

Out of total 71.565 Mt geological reserves of Gondegaon-Ghatrohan block, the geological reserves considered in Gondegaon-Ghatrohan OC mine upto 150m depth is 59.965 Mt. Rest 11.600 Mt lies in the dip side beyond 150m depth. Considering 10% geological losses due to geological disturbance e.g. Faults etc. and 5% mining losses due to losses during mining activity as per present practice, the mineable reserves upto 150m depth worked out to 51.27 Mt.

To arrive at the balance coal and OB as on 01.04.2019 for the proposed Mining Plan of Expansion of Gondegaon Extension Opencast Project, actual coal and OB extracted upto 31.03.2019 have been deducted from the total coal and OB (29.23 Mt coal and 121.31 Mm3 OB) of the approved RPR of November, 2015.

5.3 TARGET PRODUCTION

Based on the Geo-mining parameters such as strike length, gradient, thickness of seam, average rate of deepening of opencast quarries in WCL and production performance in existing mine, the target production in the proposed Mining Plan for Expansion of Gondegaon Extension Opencast Project has been envisaged as 3.50 Mty.

5.4 MINE LIFE

The total mineable reserves in the proposed mine as on 1.4.2019 is 18.29 Mt and with a target production of 3.50 mty, the balance life of mine has been envisaged as 6 years starting from 01.04.2019.

6.2 SELECTION OF MINING METHOD

Expansion of Gondegaon Extension Opencast Project which is Amalgamation of Gondegaon – Ghatrohan OC is already in operation with Shovel Dumper system of mining and hence same technology has been envisaged in this proposed Mining Plan. Deployment of dragline is ruled out due to multi-seam working and varying thickness of partings between the coal seams. Due to steep gradient (1 in 3.5 to 1 in 5), Surface Miner deployment is also not

Page - 25 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) feasible. Shovel-Dumper Technology is most flexible system and moreover, well adopted in coal mines of WCL. Considering the average gradient of mine inclined slicing method is envisaged in proposed mine.

6.3 EQUIPMENT SELECTION

In this Mining Plan, it is envisaged to excavate partially coal and OB by departmental HEMM keeping in view available capacity of Departmental HEMM as on 01.04.2019. Balance workload of coal & OB will be removed by hiring/outsourcing agency.

6.4 MINING SYSTEM AND SYSTEM PARAMETERS

6.4.1 Width & Height of Benches

For overburden, keeping the bench height of 10 m, the width of working and non-working benches are kept as 30 m and 20 m respectively. Haul road would be constructed on the floor of the quarry at a gradient of 1 in 16 with a width sufficient for dumper movement, dozer path, drainage and electrification etc.

6.4.2 Slope of Benches & Quarry

i) During Mining Operation

The slope of individual benches depends on the type of strata. In this report, the slope of individual bench is proposed as 45o in soil, alluvium and clay whereas, it is 70o in hard strata. The overall slope of the quarry in dip side during mining operation varies around 22o (from horizontal plane) depending on the nature of strata in the entire depth of quarry.

ii) At the end of quarry

The slope of individual benches in the batter at the end of quarry remains same as that during mining operation i.e. 45o in soil, alluvium and clay and 70o in hard strata. Overall angle considered during planning is about 400 in dip side & about 370 in rise side. However, it is proposed to do scientific study for slope stability in quarry benches and OB dumps by any scientific agency.

7.0 MINING AND DUMPING STRATEGY

7.1 CONSTRAINTS ON MINE DEVELOPMENT

Following constraints are apprehended in mining :

Sl. Constraint Associated Risk No. 1 Gondegaon village Delay shall affect dumping schedule. Rehabilitation 2 Land acquisition Delay shall affect dumping schedule.

7.2 MINING STRATEGY

7.2.1 Presently, Expansion of Gondegaon Extension Opencast Project which is Amalgamation of Gondegaon and Ghatrohan OC is being worked in Partial Hiring option.

The target capacity of Gondegaon Extension Opencast Project is 3.50 Mty. Both Gondegaon and Ghatrohan sub-quarry will be worked simultaneously by deploying existing departmental HEMM as well as out-sourced HEMM. The capacity of departmental HEMM varies from 5.51 Mm3/year to 6.23 Mm3/year depending on the lead and lift of coal and OB. Initially, entire departmental HEMM will be deployed in Gondegaon sub-quarry and the entire balance coal and OB of this sub-quarry as on 31.03.2019 will be extracted. In addition to departmental HEMM, part OB of Gondegaon sub-quarry will have to be excavated through out-sourcing agency.

The balance coal and OB from Ghatrohan sub-quarry as on 31.03.2019 will be worked by out-sourcing agency till exhaustion of reserves in Gondegaon sub quarry and thereafter departmental HEMM from Gondegaon sub-quarry will be shifted to Ghatrohan sub-quarry. The entire coal and OB of Ghatrohan sub-quarry will be worked in 6 years which is the total balance life of mine. The OB excavated from Gondegaon Sub-quarry will be partly accommodated in simultaneous internal dumping in Gondegaon sub-quarry and partly in external OB dumps. The balance OB from Ghatrohan sub-quarry will be

8.0 MINING SCHEDULE AND EQUIPMENT PHASING

8.1 DESIGN CRITERIA

The Mining Plan of Gondegaon Extension Opencast Project which is Amalgamated Gondegaon Ghatrohan OC has envisaged 330 days of working in a year based on 7 days schedule of mine working. As per the prevalent practice in WCL, there will be 3 working shifts in a day and each shift will be of 8 hours duration. The excavation category of OB material has been assumed as 50% Category– III + 50% Category-IV, whereas, for coal it is assumed as Category-IV. The in-situ volume weight of OB material has been considered as 2.1 t/m3 whereas for coal it is taken as 1.60 t/m3.

8.2 CALENDAR PROGRAMME OF EXCAVATION

Calendar Programme has been prepared on the basis of separate estimation of coal and overburden in various cuts of Gondegaon and Ghatrohan sub-

Page - 29 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) quarries. Based on quarry-wise and cut-wise coal, OB and stripping ratio, year-wise natural OB has been assessed for planned production of coal. Thereafter, year-wise programmed OB has been planned to minimize the peak OB.

The Cut-wise coal, OB and stripping ratio is tabulated below : -

Cut-wise Coal, Natural OB (top OB & Parting) & Stripping Ratio as on 01.04.2019

The Calendar Programme in the proposed Mining Plan of Gondegaon Extension Opencast Project which is Amalgamated Gondegaon Ghatrohan OC has been prepared for target production of 3.50 Mty and the annual peak OB of 22.85 Mm3. The balance coal reserves and overburden have been estimated as on 01.04.2019 and the first year of the Mining Plan has been considered as 2019-20. Calendar Programme has been drawn up separately for Gondegaon OC and Ghatrohan OC. The sequence of mining shall be as per the Balance of Cut-A+B in Gondegaon OC and Cuts-C, D, E of Ghatrohan OC.

The end limit floor contours of these cuts are shown in Quarry and Surface Layout Plan. It is imperative that this sequence of mining be strictly adhered to in order to obtain void for backfilling so that the dumping programme can be achieved. The basic mining strategy at Ghatrohan OC is to work the quarry in full strike keeping downthrown side advance up to the major up thrown strike

Fault F1-F1 so that the void thus created can be subsequently utilized for backfilling while working at up throw side.

9.1 PROJECTED COAL QUALITY

The RPR of Amalgamated Gondegaon Ghatrohan OC mine was discussed in the meeting of Technical Sub-Committee of WCL Board held on 07.03.2018 at WCL (HQ), Nagpur. In the meeting, it was discussed that there is wide difference in the quality of upper set of coal seams (Seam-V and IV) and lower set of coal seams (Seam-III & II) in Gondegaon Extension Opencast Project which is Amalgamated Gondegaon Ghatrohan OC mine. Finally, it was decided that separate coal stocks and dispatch arrangement for inferior quality coal of Seam-V and IV and better quality coal of Seam-III & II will be maintained in the mine and accordingly, sale price of both type of coal will be considered separately as per their corresponding year-wise quantity .

Based on the above decision, year-wise quantity of coal of upper set of seams (V & IV) and lower set of seams (III & II) alonwith corresponding quality of coal have been estimated separately. GCV of coal extracted from Seam-V and IV will fall in G-10 band while coal extracted from Seam-III and II will be border line of G-7 & G-8.

10.0 PROVISION OF PUMPS, PIPES AND PIPE FITTINGS

Pumping system has been designed for the volume of water accumulated in the mine at the target plus five year production considering maximum rainfall in a day as 190mm.

Peak pumping capacity worked out as 327389 m3. Above volume of water will be dewatered in 5 days at the rate of 20 hrs pumping per day. Pumping capacity per day thus worked out as 65478 m3.

10.1 COAL HANDLING ARRANGEMENT

Presently, there are two streams (CHP – I & CHP –II ) in existing Gondegaon Ghatrohan OC mine, wherein coal is crushed by feeder breakers and discharged on to 1200 mm wide conveyors and thereafter to a fixed grizzly which in turn discharges coal on to 60t capacity overhead hoppers. One additional mobile crusher was proposed to be operated departmentally. This mobile crusher has not been procured till date. Extra manpower has been Page - 36 MINING PLAN

14.2 SERVICE BUILDINGS

Keeping in view the needs and requirements of this mine, provision for service buildings such as office & stores, first aid centre and other buildings have been provided. As per requirement of project authorities, provision for Managers Office, renovation of excavation office & Sub-area Manager Office, Hard Stand for dumpers etc. have been provided.

It should be ensured that all the Service buildings are constructed on non-coal bearing area.

14.3 RESIDENTIAL BUILDING

Total manpower proposed for this project is 921 However, considering the availability of 340 nos. of existing houses in the neighborhood, no provision for Residential buildings has been envisaged except for 1.80 km boundary wall for existing colony.

14.4 ROADS AND CULVERTS

Colony Roads and Culverts

As there is no new colony, hence no colony roads are provided.

Haul Roads & Culverts

Transportation of part of total OB is proposed to be done by Hiring of HEMM & provision of 4.00 km haul road has been kept as per 60T Dumper specification.

Service Roads & Culverts

For approaching different Service Buildings, 0.50 km additional road is needed & provisions have been made .

Diversion and Strengthening of Road

Diversion of 2.50 km of existing village cart roads have been envisaged in this Mining Plan.

Page - 39 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) Further provision of 2.50 km of surface road has been kept in order to take care of diversions in the existing surface roads because of re-alignment of surface dumps.

As per requirement of project authorities, further provision for Public Road fly- over for dumper crossing have been provided near Ghatrohan village .

14.5 WATER SUPPLY AND SEWERAGE

No additional residential quarters have been provided in this Mining Plan and therefore there is no provision for colony water supply and sewerage.

15.0 SAFETY & CONSERVATION

The project report has been drawn in conformity with the prevailing statutory provisions applicable for safety in Opencast Mines. However following matters related to safety during opencast operations have to be given special considerations.

15.1 PRECAUTIONS AGAINST SURFACE WATER

Ghatrohan Sub-quarry is at 100 m distance from Kanhan river and a part of quarry falls below HFL. The HFL of Gondegaon & Ghatrohan Opencast block is 279.035 m recorded on 7th Sept.1994 by Inder Colliery Survey Office. Since there is a danger of flood water from Kanhan river to proposed quarry, a flood protection embankment has been proposed. The proposed embankment is 30m wide at the top and of height 6m above HFL. As per prevailing practice, proposed embankment has to be constructed by spreading the suitable soil i.e. fine grained soil for Hearting zone and coarse grained soil for casing zone in continuous layers and compacted by mechanical means i.e. by rollers to standard optimum dry density at optimum moisture content. Also it has been proposed to provide 300 mm thick boulders pitching on water side of embankment upto HFL. However for portion of embankment where the surface level is higher than the HFL, no pitching has been envisaged.

Page - 40 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) However before adoption of this section it is suggested that the proposed embankment section may be got approved by competent authority like Maharashtra Irrigation department of Govt. of Maharashtra and DGMS for its structural safety and stability. The alignment of the proposed embankment is shown in Quarry Layout Plan. It is also suggested to determine withdrawal level/Danger mark, so that as water level crosses the limit, workings shall be stopped.

Suitable alarms connected to float in Kanhan river would be provided at strategic places like Time Keeper Office, Security Office, Safety Office, Manager Residence, Pit Office etc. The floats in the river would activate the alarms as soon as the water level in the river crosses the danger mark. Suitable action can then be taken to investigate the alarm and take other suitable precautions. In addition, river side patrolling would also be carried out during monsoon to caution the project authority in case of any sudden rise in the river. Adequate wireless communication sets have been provided for the above purpose. The rain water falling within the project area would be diverted from the quarry area by providing garland drains and shall be collected towards low lying area.

15.2 DUST SUPPRESSION

For suppression of dust water sprinkler has been provided. Suppression of mine dust may be done by using package bond & dust bond, for methodology of application DGMS Circular No.8 of 1997 may be referred.

15.3 FIRE & SPONTANEOUS HEATING

Wild or herbaceous plants shall be removed from the mine. No person shall deposit heated material or ashes on any opencast working. Also no person shall light a fire or permit a fire to be lighted in any OC working except by the permission in writing of the Manager and only for a special purpose specified therein. No coal shall be left exposed in coal benches more than its incubation period to avoid fire in seam due to spontaneous heating. Proper type of the extinguisher to be kept in each HEMM ready for use in case of emergency. One Fire Fighting Truck has been provided in this report. Page - 41 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019)

In coal stock, coal shall be despatched on the basis of first in first out.

15.4 SLOPE STABILITY

It is suggested that following action may be taken to deal with slope stability problem.

15.5 HAUL ROAD MAINTENANCE

Adequate care must be taken for proper construction and maintenance of haul road as per the existing guidelines. The gradient of haul road should not be steeper than 1 in 16.

15.6 BLASTING OPERATIONS

As explosives are required in bulk for blasting in OC mines, provision of regulation should be ensured. All blasting operations shall be carried out in day light. Suitable precautions shall be taken as per statute before and after blasting operations. Controlled blasting technique has to be practised to minimise fly off rocks and ground vibrations and keep them within safe limits . In order to keep the ground vibrations within the permissible limit, to avoid flying of rock fragments and also to achieve satisfactory blasting results, optimized drilling / blasting parameters depending upon rock formation using combination of relays / delays will have to be evolved. It is further recommended that at the time of actual execution, proper study for controlled blasting and ground vibration is done with scientific body in order to evolve site specific charge distance relationship.

15.7 SCIENTIFIC STUDIES

Following areas have been identified in the proposed mine for detailed scientific studies:

a) Slope Stability

It is proposed to carry out scientific study on slope stability of external and internal OB dumps as well as for final slope of quarry batter. Based on the findings of scientific research the proposed slope of dumps and batter in the report may change.

b) Drilling & Blasting

For optimum fragmentation of rock and coal to minimize the overall cost of excavation, it is proposed in this report to engage some scientific body to carry out research for optimum drilling and blasting. Accordingly, the powder factor suggested after this study will be followed in the proposed mine. Page - 43 MINING PLAN

16.0 ENVIRONMENTAL MANAGEMENT

Page - 45 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) year subject to compliance of certain terms & conditions and environmental safeguards. Later on, the Ministry of Environment, Forest and Climate Change vide letter no. J-11015/106/2009-IA.II(M) dated 28.03.2019 accorded approval for continuance of Gondegaon Extension Opencast Mining Project from 2.50 MTPA to 3.50 MTPA in area of 917 ha (mine leasehold area 845.74 ha) for a further period of one year.

The RPR for Amalgamated Inder-Kamptee Deep OC was approved by WCL Board in September, 2018 in which 54.34 ha land was proposed to be transferred from neighbouring Gondegaon-Ghatrohan OC. Accordingly, EC application for amendment in EC of Expansion of Kamptee Deep OC for a capacity of 3.20 MTPA within a mine lease area of 857.60 ha was discussed in EAC in its 46th meeting held on 25.06.2019. The EAC, after deliberation observed that the proposed amalgamation involves carving out some area of adjoining Gondegaon Opencast coal mining project and thus requiring amendment in its environmental clearance also. There being no proposal in this regard, the committee was not inclined to take the proposal forward.

The likely impact of Expansion of Gondegaon Extension Opencast project on the environment and various mitigation measures are detailed below :

16.1 AIR QUALITY MANAGEMENT

Air pollution is likely to be generated due to dust, exhaust from vehicles, blasting fumes etc. In opencast mines, dust is likely to be produced during blasting, crushing of coal, handling of overburden and coal, drilling and operation of HEMM. The following measures have been proposed to control air pollution :

i) Water spraying is to be carried out on haul road at regular interval during each shift.

ii) Water spraying arrangement at dust generating points in CHP, feeder breaker, conveyor transfer points etc.

iii) Proper maintenance of all internal combustion engines to reduce smoke and exhaust fumes.

Page - 46 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019)

iv) Dust extractors in working condition in all the drills.

v) Tree plantation in rows and blocks along the approach road of the mine and also along the coal transportation road on both sides.

vi) Perimeter tipping of external overburden dumps. Tree plantation on the slope of the perimeter dump.

vii) Water spraying mixed with safe and non-toxic dust suppression chemicals on haul roads during dry months.

viii) Coal transportation in trucks covered with tarpaulin.

ix) Avoiding overloading of trucks.

x) Frequent cleaning of coal transportation road.

xi) In order to replace, transportation of coal by road, construction of pipe conveyor system is in progress for carrying coal from the mine head to Koradi TPS.

16.2 WATER QUALITY MANAGEMENT

The quantity of mine water pumped out would vary according to the season. The mine water may contain various impurities like coal dust, traces of grease, oil etc. in various proportions. The mine water would be allowed to collect in the quarry sump where primary settling would take place. The mine water would then be pumped into secondary settling tanks on the surface.

Here the water would be allowed to settle and thereafter part of treated water will be utilized for meeting in -house water requirement (like dust suppression, watering of plants, washing of HEMM, potable use etc). Peripheral trenching is recommended near external OB dumps for coursing the run-off and leached water from the dumps. If required, the water may be sent to surface settling tanks before discharging it into the drainage channels.

The used water from the industrial area comprising CHP, Workshop, Garage etc. may be contaminated with grease, oil, coal dust, dirt etc. This water will

Page - 47 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) be allowed to settle and suitable treatment will be carried out in oil and grease trap. Thereafter the treated water will be mostly recycled.

16.3 GROUND WATER MANAGEMENT

Due to proposed project, it is anticipated that the effect on ground water regime will be pronounced upto around 500 m from mine edge and effect will be pronounced in the down-dip side and milder in the up-dip side. But this effect will be temporary in nature and once the project is over, after 2 – 3 rains, the regime will regain its almost original status. Any shortage of water in the affected villages during the temporary period will be supplemented through supply of treated water pumped out from the mine.

16.4 NOISE AND GROUND VIBRATION MANAGEMENT

Existing noise level at the mine site (wrt pre-mining level) is likely to increase and following measures are being suggested to reduce noise and ground vibration effects:

i) With judicious use of explosives and correct blasting techniques, ground vibration and noise pollution would be reduced.

ii) Structures prone to vibration or those with moving parts are suggested to be inspected periodically and source of vibration should be damped to minimize noise and vibration.

iii) Proper maintenance of HEMM and exhaust silencers.

iv) Vegetation barrier around the service buildings will act as effective acoustic barrier.

v) Ground vibration and fly rock can be controlled by proper use of delay detonators. This will help to reduce the noise pollution.

16.5 FLORA AND FAUNA MANAGEMENT

No Changes in the diversity of species or number of any species of animal and no reduction in the number of any unique, rare or endangered species of animals are anticipated. Any deterioration to existing fish or wild life habitat

Page - 48 MINING PLAN

MINING PLAN FOR EXPANSION OF GONDEGAON EXTENSION OC MINE (AUG., 2019) due to mining is ruled out. Similarly, no changes in the diversity of species or number of any species of plants and also no reduction of the number of unique, rare or endangered species of plants are anticipated.

Adequate plantation has been proposed with native species to maintain the diversity and also to attract the fauna.

The RPR for Amalgamated Inder-Kamptee Deep OC was approved by WCL Board in September,2018 in which 54.34 ha land was proposed to be transferred from neioghbouring Gondegaon-Ghatrohan OC. Accordingly, EC application for amendment in EC of Expansion of Kamptee Deep OC (which is neighbouring mine of Gondegaon-Ghatrohan OC) for a capacity of 3.20 MTPA within a mine lease area of 857.60 ha was discussed in EAC in its 46th meeting held on 25.06.2019. The EAC, after deliberation observed that the proposed amalgamation involves carving out some area of adjoining Gondegaon Opencast coal mining project and thus requiring amendment in its environmental clearance also. There being no proposal in this regard, the committee was not inclined to take the proposal forward.

Hence, for applying for amendment in the existing EC of Expansion of Gondegaon Extension OC, Mining plan for a capacity of 3.50 MTPA for mine lease area of 791.40 ha has been prepared for approval from Competent Authority.
