VIMTA Labs Limited, Hyderabad 4 Pre-Feasibility Report for Enhancement of Production through Opencast Method of Mining in Gare Palma IV/4 Coal Mine, Chhattisgarh

The Gare Palma IV/4 opencast coal mine has an area of about 885.525 ha and situated in the eastern part of Gare Palma Coalfield. It is a running mine having production capacity of 1MTPA [(OC-0.56+ UG-0.44 MTPA)] presently. Revised Mining Plan (including Mine Closure Plan) for Gare Palma IV/4 Coal Block (4th Revision) has been prepared based on geological report namely “Geological Note on Detailed Coal Exploration in Gare Palma IV/4 Block, Mand Raigarh Coalfield, Raigarh District., Chhattisgarh state”, August 2018 prepared by South West Pinnacle Limited and “Geological Report on Detailed Coal Exploration in Gare Palma IV/4 & IV/5 (Integrated), Mand Raigarh Coalfield, Raigarh District., Chhattisgarh state”, December 2017 prepared by South West Pinnacle Limited. It has been prepared based on the fresh exploration undertaken by M/s Hindalco Industries Limited.

Net Available Geological Reserves has been estimated as 64.955 Million Ton. The Revised Mining Plan (including Mine Closure Plan) for Gare Palma IV/4 Coal Block (4th Revision) has been prepared for switching to total mechanised opencast mining from the present mix of underground mining and opencast mining method with the following assumptions:

i. To maintain the production programme for first three years as per the approved Revised Mining Plan & Mine Closure Plan (3rd Revision) of Gare Palma IV/4 Coal Mine i.e. 0.44 MTPA by underground production and 0.56 MTPA by opencast mining; ii. To convert the entire mining operation to opencast mining in fourth and fifth year; and iii. To increase the annual production from 1.0 MTPA to 1.5 MTPA in the fifth year and then to maintain 1.5 MTPA as the target/peak annual production rate.

2.3 Need for the Project

Revision of the Approved 3rd Revision of Mining Plan of Gare Palma IV/4, August 2018 has been necessary for the following reasons:

1. After analyzing the information for location of historical boreholes w.r.t revised block boundary as per certification of CMPDI, chemical analysis data, geophysical data, seam data co-relation with the surrounding new boreholes and underground and opencast mine working, etc. 74 boreholes have been shortlisted for the preparation of the “Geological Note on Detailed Coal Exploration in Gare Palma IV/4 Block, Mand Raigarh Coalfield, Raigarh District., Chhattisgarh state”, August 2018 prepared by South West Pinnacle Limited and “Geological Report on Detailed Coal Exploration in Gare Palma IV/4 & IV/5 (Integrated), Mand Raigarh Coalfield, Raigarh District., Chhattisgarh state”, December 2017 prepared by South West Pinnacle Limited. Seams I, L1, L2, II, IIT, IIB, III, IV and V have been considered in this report and the estimated Net Geological Reserve considered in the 4th revision has been increased to 64.955 Mt (which includes the Reserve already depleted till 31.03.2018). This Revised Mining Plan (including Mine Closure Plan) for Gare Palma IV/4 Coal Block (4th Revision) has been prepared based on the above Geological Note, August 2018. The mining plan is applied for approval vide Lr No HIL/GP-IV/4/Mine Plan/2019- 20/234 dated 31st May, 2019 and enclosed as Annexure-I. The existing EC,

transfer of EC & its amendment are enclosed as Annexure–II, Annexure–III & Annexure–IV respectively.

2. It is a running mine and the underground mining operations through developments of seams II and III have been completed. Only depillaring can be done to continue the production of underground mining. It will be difficult to match the rated production capacity in this case. Multiplicity of seams will stand in the way except by stowing for which adequate stowing material is not available. Extraction Percentage of the reserves will also be less by underground method of mining compared to the opencast method.

3. It has been found that the stripping ratio and other conditions are favorable to convert the entire mining operations upto the Bendra Nala (flowing to the south) to opencast mining and it will be safer and will yield higher extraction percentage.

Hence, the Revised Mining Plan (including Mine Closure Plan) for Gare Palma IV/4 Coal Block (4th Revision) has been planned for complete opencast mining operations except for initial three years in which both opencast and underground working has been considered same as earlier approved 3rd Revision of Mining Plan of Gare Palma IV/4. The total extractable coal has increased to 23.06 Mt which is almost double of the extractable reserve 12.71 Mt planned earlier in 3rd revision. The annual production target has been increased to 1.5 MTPA against 1 MTPA in earlier 3rd revision and mine life has increased to 18 years compared to 13 years earlier.

The net extractable reserve is 23.06 MT and the life of the mine will be 18 years.

3.5 Project Description with Process Details

3.5.1 Physiography

Physiographically, the block IV/4 can be divided into the hilly terrain covered by Forest in the north-central and eastern part and relatively plain country north and south of it. The area is traversed by the southwest-northeast trending Dumar nala in the north and Bendra nala in the south. Kelo River is the main drainage in the area and flows in west of the adjacent Gare Palma IV/5 coal block.

The elevation of the area north of the hilly terrain varies between 268 m and 330 m whereas the hill rises upto 432 m above mean sea level. Southern part of area is depicted by rolling topography. The area immediate to the south of terrain is more or less plain with gentle slope towards southeast and the elevation ranges between 264 m and 290 m. The area south of Bendra nallah is represented by a rolling topography with ground elevation ranging between 267 m and 301 m and this part is mostly covered by forest. Isolated hillocks of lesser magnitude are also evident in the west central part. The drainage of the sub block is controlled by Kelo River that flows in WNW of the adjacent Gare Palma IV/5 coal block. Dumar and Bendra nalas collect water from slopes of the terrain and discharge into Kelo River. Water from Kelo River is finally discharged into Mahanadi River.

3.5.2 Regional Geology

Gare Palma IV/4 coal block form a part of Mand Raigarh coal field. Mand Raigarh Coalfield is located in Raigarh district in Chhattisgarh state. It lies in the valley of the Mand River, a tributary of the Mahanadi. The Mand Raigarh Coalfield covers an area of about 900 sq. km in the north-westerly continuity of the Ib River Coalfield of Odisha. Mand Raigarh Coalfield includes the areas earlier known as North Raigarh, South Raigarh and Mand River Coalfields. Of at least twelve seams in the Mand Valley, the Mand and Taraimar seams are important.

The Coalfield is a part of the extensive spread of Gondwana Formations, extending from Hasdeo - Arand Coalfield through Raigarh basin to Ib River Coalfield to the south-east in the Sambalpur district of Odisha. The Korba Coalfield is also a western

VIMTA Labs Limited, Hyderabad 12 Pre-Feasibility Report for Enhancement of Production through Opencast Method of Mining in Gare Palma IV/4 Coal Mine, Chhattisgarh

extension of the Mand River Coalfield. A large part of the intervening terrain in between these coalfields is covered by Kamthi sediments. The field has a potential for mining of power grade coal, much of which can be extracted through open cast mining. Gare block has been identified for captive mining by private companies.

The Mand Raigarh Basin stretches between Latitudes 21 45’ & 22 42’ and Longitudes 83 01’ & 83 44’ extending over an area of about 900 sq km in the ⁰ ⁰ Raigarh district of Chhattisgarh State. The stratigraphic succession in Mand Raigarh ⁰ ⁰ coalfield as a whole is furnished in Table–4.

The geological formations in the Mand Raigarh Coalfield as described by GSI are presented below:

Archaeans: The Archaeans occur along the northern as well as southern boundaries of coalfield and are represented by garnetiferous granite gneisses, mica schists, & pegmatites. These are exposed to the north-east of Dharamjaygarh. The contact

VIMTA Labs Limited, Hyderabad 13 Pre-Feasibility Report for Enhancement of Production through Opencast Method of Mining in Gare Palma IV/4 Coal Mine, Chhattisgarh

with Talchir is observed in Konja nala and in the east of Dharamjaygarh (GSI, 1984).

Chhattisgarh Formation: Achaeans are overlain by Chattisgarh Formation represented by quartzites and phyliites. These are ferruginous at places and found to be forming hill ranges in the southern part of the coalfield.

Talchir Formation: Exposures of Talchir Formation are found in the northern part of Dharamjaygarh- Khargaon area. In this part, the maximum thickness of Talchir is about 40 m and it is represented by boulder bed, grey to greenish grey shale, fine to medium grained sandstone and siltstone. Borehole information reveals that the thickness of Talchir formation is not less than 162 m (ref- GSI Borehole no MRK-5). The Talchirs are not contiguous and pinch out strike-wise. Metamorphics are in direct contact with the Barakars at many places.

Barakar Formation: Barakar is a major coal bearing formation in the coalfield which overlies conformably with gradational contact. Most of the area of Barakar formation is covered by forest and alluvium with limited exposure of the formational rocks in nallas and river sections. Total thickness of this formation in northern part is 706 to 840 m (Kamar Guru et al 1980) while that in the southern part as in Chhal is about 950 m (GSI Borehole no. MRC-1 & MRC-5). The major rocks are mainly sandstone with subordinate shale, frequently interbanded with carbonaceous shales and coal seams. The sandstones are poorly sorted, white to greyish white in color. The fine grained sandstones are micaceous while coarse grained are massive and arkosic. On the basis of gross lithological attributes (GSI 1989), the formation has been sub divided as: Lower, Middle and Upper members. The middle member is more argillaceous and the lower & upper members are more arenaceous. Only the lower and upper members are present in Gare area (GSI, 1992).

Barren Measure Formation: Barakar formation is conformably overlain by Barren Measure formation comprising of greyish black to black shale and fine to medium grained sandstone. Argillaceous facies is predominant over arenaceous facies in this formation and frequently occurs as thick alternation with the latter. The thickness of this formation is about 250 to 300 m.

Raniganj Formation: Raniganj formation conformably overlies Barren Measure Formation. With gradational contact. Major lithologies in this formation are fine to coarse grained sandstone, siltstone, grey shale, carbonaceous shale and thin coal seams. The formation has scanty exposure and mostly covered by alluvium.

Kamthi Formation: Kamthi formation lies unconformably overlies Raniganj Formation and occurs as NW-SE running linear patch in central and south-eastern part of the coalfield. These form hill range in many places. The major lithologies are coarse to pebbly sandstone with red clay bands. The sandstones are highly ferruginous and cross bedded. Total thickness of Kampthi formation is about 250 m.

Igneous Intrusives: Occurrence of several dykes stretching from 6 to 26.5 kms, Sills and flows have been noted in the northern part of the coalfield. The basic rocks are fine grained basalts to coarse grained gabbroid types.

Coal Seams:

12 coal seams designated as XII and below occur in Barakar formations in the area. The younger seams i.e., IV and above are generally high moisture and high ash (Grade E to G) power coal, whereas seams III, II & I are likely to contain superior grade coals (Grade A-D). The coalfield is likely to contain over 500 million tonnes of superior grade coal which could be utilized as such or after beneficiation for sponge iron production.

As per inventory of Geological Resources of Indian coal (as on 1st April,2018) prepared by the GSI, Mand-Raigarh Coalfield contains 30249.41 million tonnes of coal reserves up to a depth of 1200 m.

Gare Palma IV/4 has been an operational mine and currently the coal is being taken out by both opencast as well as underground mining method. The 3rd revision of Mining Plan of Gare Palma IV/4, August 2018 has been approved vide letter No. 34011/04/2018 (CPAM) dated 13.12.18 for rated capacity of 1.0 MTPA out of which productions by opencast is 0.56 MTPA and by underground is 0.44 MTPA.

It has been proposed in this Revised Mining Plan (including Mine Closure Plan) for Gare Palma IV/4 Coal Block (4th revision) to continue the production programme as per that proposed in the latest approved 3rd Revision of the Mining plan, August 2018. Accordingly, mining operations will be both by opencast and underground method till first three years. The underground mining will include depillaring of seams III and II which have already been developed. Opencast is being done in two sections namely North pit and South pit as these are existing in north and south of Dumar Nala. The 1st and 3rd year stage plans have thus been reproduced as proposed in 3rd Revision of the mining plan, August 2018. The mining plan is applied for approval vide Lr No HIL/GP-IV/4/Mine Plan/2019-20/234 dated 31st May 2019 enclosed as Annexure–1.

The 4th and 5th years will be the conversion years of underground operations to opencast mining. Mining operations will be ceased by underground method in 4th year.

In the north pit dismantling of all the underground infrastructures and inclines will take place. The North pit opencast operations which is concentrated towards the eastern side will now be advancing towards the Western side. The split seam II Top is the base seam till the workable seam thickness of II Bottom is obtained as the mine progresses towards the western side. North pit will be exhausted by the end of 5th year.

In the south pit opencast mining operations will be advancing towards both western side as well as southern side towards Bendra Nala in the 5th year of mine life. From 6th years onwards the opencast mining operations will be concentrated fully in the South pit. The mining operations initially be on seam III floor as other seams are not developed in this region. The bottom seam II is encountered in the 7th year and the mining operations goes down to the floor of seam II. The mining operations will be advancing to reach the final opencast mine boundary both in the southern side upto the safe distance from the Bendra Nala and also to attain the final shape in the western side. After reaching the final shape in southern boundary and corresponding western boundary the operations will be advancing towards the northern side.

Total extractable reserve has been estimated as 23.06 Mt. Out of this 21.74 Mt is by opencast mining and 1.32 Mt is by underground mining operations. Corresponding to 21.74 Mt of opencast coal extraction, 220.52 Mcum of overburden removal has been estimated. The average stripping ratio of the opencast mine is 10.14 cum/t. The production schedule for coal production and overburden removal is shown in the following Table-6. TABLE–6 SCHEDULE FOR COAL PRODUCTION AND OVERBURDEN REMOVAL

3.5.6 Geological & Mining Characteristics

In Gare Palma IV/4 block, there are seven seams namely Seam V, IV, III, II, L2, L1 and I. Seam II is splitted into II Top and II Bottom seams in the north side of fault F3-F3’. Seams III, II, II Top and II Bottom seams are workable seams in the area above Bendra Nala. Seam L2 & L1 and Seam I are developed in only limited areas in the block north of Domar Nala but are inaccessible for mining due to depth and VIMTA Labs Limited, Hyderabad 17 Pre-Feasibility Report for Enhancement of Production through Opencast Method of Mining in Gare Palma IV/4 Coal Mine, Chhattisgarh

narrow width of the North Pit. Seam IV & V incrop in the area south of Bendra Nala. The major part of Seams lies under the existing dump of Gare Palma IV/2 coal mine. The area south of Bendra Nala has not been considered favorable for opencast mining as the stripping ratio goes beyond 1:20.

North and south pits have been proposed for expansion in order to take out the underground working after their operations cease at the time of starting of its conversion to opencast. The ultimate pit configuration plan is represented in Figure- 4.

The ultimate pit of north pit of the Gare Palma IV/4 mine has been delineated as follows:

East: Upto the existing eastern boundary of north pit West: Keeping 7.5 m from the block boundary North: Keeping 7.5 m from the block boundary, Upto a vertical cut-off stripping ratio of 10 and upto seam extent South: Keeping safe distance of 60 m from the Domar Nala.

The ultimate pit of south pit of the Gare Palma IV/4 mine has been delineated as follows:

East: Upto a vertical cut-off stripping ratio of 10 and upto seam extent West: Keeping 7.5 m from the block boundary North: Keeping safe distance of 60 m from the Dumar Nala South: Keeping safe distance of 60 m from the Bendra Nala.

3.5.7 Product–Mix Quality

Existing opencast mine has been working in two pits namely north pit which is in north of Dumar nala and south pit which is in south of Dumar Nala and will continue as such. In Gare Palma IV/4 block there are seven seams namely Seam V, IV, III, II, L2, L1 and I. Seam II is splitted into II Top and II Bottom seams in the north side of fault F3-F3’. Seams III, II, II Top and II Bottom seams are workable seams in the area above Bendra Nala. Seam L2 & L1 and Seam I are developed in only limited areas in the block north of Domar Nala but are inaccessible for mining due to depth and narrow width of the North Pit. Seam IV & V incrop in the area south of Bendra Nala. The major part of Seams lies under the existing dump of Gare Palma IV/2 coal mine. The area south of Bendra Nala has not been considered favorable for opencast mining as the stripping ratio goes beyond 1:20. So only seam III & seam II and seam IIT and II B is considered for mining and the detail quality of the seams is given in Table–7.

3.5.8 Transportation of Coal

It is proposed that coal from the mine will be dispatched by road to its end use plant located at Aditya Alumina, Lapanga (130 km) & Hirakud (160 km) in Odisha in covered trucks. In future, a nearby upcoming railway siding may be used for loading and evacuation of coal.

3.6 Raw materials required along with estimated quantity, likely source, marketing area of final product/s, Mode of transport of raw material and finished product.

No raw material is required as this is a mining activity. Only explosive to blast coal & OB and diesel for transportation of vehicles, operation of HEMM and generators in case of Power failure. Coal dispatch will be continued as per prevailing system and the ROM coal produced from mine will be hauled by 40T rear dumper and will be stored at surface stock yard. The same will be loaded on dispatch trucks by pay loaders for dispatch to end use plants. A CHP system has been proposed at surface for receiving, crushing of coal up to (-) 100 mm size, conveying and loading into trucks. In future a nearby upcoming railway siding may be used for loading and evacuation of coal. A CHP system has been proposed at surface. Coal from hoppers, shall be loaded in to trucks through vibrating feeders / Hydraulic Gate provided below each hoppers. Coal will be transported at nearby siding for final loading into railway wagons for transportation up to consumer plant.

Coal will be finally loaded into railway wagon at nearby upcoming/proposed siding through mechanized loading system or transported to EUP (end use plant).

3.7 Resource Optimization/ Recycling and Reuse envisaged in the Project, if any, should be given.

Resources like explosives, diesel oil, machinery, land, power and water are fully optimized to minimize unnecessary losses during the process of excavation and supply of coal to the captive plant. The peak production capacity from mine will be 1.5 million tonnes per annum. The coal does not require beneficiation. The resources which are used in the mining will be recycled by various methods. Sludge generated from domestic wastewater treatment will be composted and used as manure. Used oil from HEMM & DG set, will be sold to the authorized vendors. The Mine seepage water collected at settling pits will be treated at ETP/RO and used for domestic

VIMTA Labs Limited, Hyderabad 20 Pre-Feasibility Report for Enhancement of Production through Opencast Method of Mining in Gare Palma IV/4 Coal Mine, Chhattisgarh

purposes such as dust suppression, mining activity, irrigation to surrounding villages.

3.8 Availability of Water its Source, Energy/ Power Requirement and Source

3.8.1 Power

Presently an underground coal mine is running in this block. To meet the power requirement of this mine one number 33/11/3.3 kV substation has been installed. Installed transformation capacity of this substation is 1 X 33/11, 5 MVA; 1 X 33/11, 6.3 MVA and 1 X 33/3.3, 5 MVA. This substation receives power at 33 kV from Dolnara Substation of CGPDL. Approximate distance of this substation from this block is around 8 km.

It is envisaged to develop an opencast coal project in this block which will subsume the existing underground mine, electrical load of the opencast project envisages mainly consists of pumps, CHP, workshop, colony, illumination system etc. All the shovels and excavators shall be diesel driven. It is estimated that total power demand for mining operation in this this block will be around 1.5 MVA.

To meet this demand, It is envisaged that existing power supply arrangement at 33 kV will be used to meet the power requirement of this project.

3.8.2 Water Supply & Sewerage

It is proposed that requirement of potable water requirement is met from the mine seepage water. The mine water is being stored in the mine pit for setlling and storage and later treated with latest Reverse Osmosis (R.O.) technology for which established RO plant of 7500 Litre per hour capacity, which is distributed for the use of mine staffs & workers and supplied to R & R colony. For supply of pure and clean drinking water tap has been provided in the R & R villages and small overhead tanks are also built-up.

3.9 Quantity of wastes to be generated and scheme for their Management/ Disposal

Solid Waste

Out of the total volume of OB estimated of 220.52 Mm3 top soil is 17.02 Cu.m. The mine have two pits the north pit north of Dumer nala and the south pit south of Dumer nala upto Bendra nala. In north pit most of the overburden material 12.69 Mcum will be accommodated inside the internal dump D5. However, a small overburden 0.23 Mcum which cannot be accommodated inside will be accommodated in the external dump D6 in the north-east of it flushing to the internal dump. The maximum RL of the dumps D5 and D6 will reach +320 m in North pit. The dump height is around 50 m above the ground level.

In the south pit opencast mining operations will be advancing towards both western side as well as southern side towards Bendra nala in the 5th year of mine life. Dumping of overburden will start in the internal dump D2. About 12.29 Mcum of overburden will be accommodated in the internal dump D2. Entire overburden

VIMTA Labs Limited, Hyderabad 21 Pre-Feasibility Report for Enhancement of Production through Opencast Method of Mining in Gare Palma IV/4 Coal Mine, Chhattisgarh

cannot be accommodated on top of the internal dump. So the external dumping will start towards the eastern side as well in dump D1. About 8.10 Mcum of overburden material will be accommodated in this external dump D1 till 5th year of mining operations. The dump RL will be +327 m RL.

Top soil from both the north and south pit will be used for reclamation purpose and excess will be stacked separately for reclamation purpose. An external dump space D3 has been allocated for accommodation of 2.4 Mcum topsoil in south of Bendra nala. The advancement of the south pit in 6th year towards its northern side will involve chopping of the western peak. It involves pre-stripping of large volume of overburden. Advancement till 10th year is crucial as the accommodation of very large quantity 119.79 Mcum of cumulative overburden is involved. Not much internal dumping space will not be created till such time. Only 34.04 Mcum overburden will be accommodated in internal dump D2 upto a maximum dumping height of 70 m (RL+340 m). External dumping space in dump D1 towards the eastern side flushing with the internal dump D2 is sufficient for accommodation of 35.85 Mcum overburden material only upto the maximum dumping height of 70 m (RL+340 m). Additional dumping space is needed to accommodate the balance overburden dump. It is required in the 7th year as shown in the below Table - 8.
