Vindhya Nagar Road, P.O. Waidhan,
District Sidhi, M.P. – 486 886.
Sub: Mahan Opencast Coal Mine Project (8.5 MTPA) of M/s Mahan Coal Company Ltd., located in village Amelia, Bhuder, Suggo, Tehsil Waidhan, District Sidhi Madhya Pradesh - environmental clearance – reg.
This is with reference to your application vide letter dated 05.12. 2006 and this Ministry’s letter dated 07.02.2007 granting the Terms of Reference (TOR) to the above-mentioned project and your subsequent application dated 03.11.2007 for environmental clearance based on TOR and subsequent letters dated 03.10.2008 and 16.12.2008 on the above-mentioned subject. The Ministry of Environment & Forests has considered your application. It has been noted that the project is for opening a new Mahan Opencast Coal Mine Project for an annual production capacity of 8.5 MTPA over a total lease area of 1090 ha. The project is to supply 5 MTPA coal to 1000 MW Power Project of M/s Essar Power Limited located at a distance of about 5 km and 3.5 MTPA of coal to 650 MW Power Project of M/s HINDALCO Industries Ltd located at a distance of 22km form the ML. Of the entire lease area of 1090 ha, 1072.35 ha of lease falls within forestland which forms a part of the Mahanban Reserve Forest, and 17.65 ha is revenue land. A number of rare and endangered fauna such as Leopard, Sloth Bear, Hyeana, Chinkara are found in the study area. A Comprehensive Wildlife Conservation Plan has been prepared. There are a number of Reserve forests such as the Vihar RF, Mohar RF and Chokra RF situated within the 10km of the core zone. Forestry clearance has been applied for. There are no National Parks, Wildlife Sanctuary, Biosphere Reserves found in the 15 km buffer zone. The block is drained by a number of seasonal nalas flowing from east to low lying areas within the ML and form a part of the Rampa river which form aprt of the Rehand River. On the western side, the drainage is controlled by River Mahan. The project involves 23 PAFs of land oustees from the villages of Budher and Amelia. Of the total lease area, quarry area will be 798.27 ha, 12 ha of topsoil dump, 138.70 ha is external OB dump, 33.17 ha is greenbelt, 35.61 ha for infrastructure facilities and roads, and 72.25 ha of undisturbed area (safety zone). The project does not involve a coal washery.
Rated capacity of the mine is 8.5 million tonnes per annum (MTPA) of coal production. Mining would be mechanised involving shovel-dumper and surface miner for coal extraction and shovel-dumper for OB removal. Coal is transported from CHP by belt conveyor to Essar Power Project and by rail to HINDALCO Power Project. Ultimate working depth of the mine by opencast operations is 160m below ground level (bgl). Groundwater in the study area is about 18m below ground level (bgl). Water table will be intersected during the first year of mining operation. Peak water demand is 2700 m3/d of water, which will be met from mine sump/pit water and from groundwater (bore wells for domestic consumption). The total estimated OB generation over life of mine would be 707.02 Mm3 and topsoil would be 3.672 Mm3. Of the total OB generation, of which about 75.5 Mm3 would be dumped in external OB dump of 120m height. OB of 48.50 Mm3 would also be temporarily stored in the mineralised area and rehandled to backfill the void. Backfilling would begin from the 3rd year onwards. The balance OB would be backfilled into the decoaled void of 626.61 ha. The total area to be brought under plantation would be 882.73 ha. In the post mining stage, an area of 171.66 ha of the decoaled void would be converted into a water body of a maximum depth of 26m. Life of the mine is 17 years. Mining Plan for the project was approved by MOC on 14.06.2007. Public Hearing was conducted on 29.07.2007 by the M.P. State Pollution Control Board. Capital cost of the project is Rs. 1700 crores.
