Sub:            Expansion of Dipka Opencast Mine (20 MTPA to 25 MTPA and expansion in project area from 1461.51 ha to 2000.642 ha) of M/s South Eastern Coalfields Ltd. (SECL), located in village Dipka, Tehsil Katghora, Dist. Korba, Chhattisgarh - (EC based on TOR granted on 22.10.2007)  – reg.



            This is with reference to letter No. 43011/76/2007-CPAM dated 30.05.2007 forwarding the application for Terms of Reference (TOR) and this Ministry’s letter dated 22.10.2007 granting TOR to the above-mentioned project and subsequent letter No. CIL/EMP-TOR/2008/03 of M/s CIL dated 24.12.2008 with application for environmental clearance based on TOR and subsequent letters of M/s SECL dated 07.01.2009,25.02.2009, 26.02.2009, 27.02.2009, 08.04.2009, and 30.04.2009 and letter of CIL dated 20.04.2009 on the above-mentioned subject. The Ministry of Environment & Forests has considered your application. The project is for expansion in Dipka Opencast Coalmine Project in terms of annual production capacity of coal from 20 MTPA to 25 MTPA and project area from 1461.51 ha to 2000.642 ha.  The project was granted environmental clearance on 04.10.2004  for a production capacity of 20 MTPA of coal in a project area of 1461.51 ha.  Of the total project area, 1406.363 ha is agricultural land, 424.522 ha is forestland, 160.757 ha is wasteland and 9 ha is surface water bodies. River Ahiran flows at a distance of 8km from the ML. There are a number of rivers and nalas such as Lilagarh nadi, Kholar nala, and channels flowing within and in the vicinity of the ML area. It is not proposed to modify the surface water drainage of the area. There are no National Parks, Wildlife Sanctuary, Biosphere Reserves found in the 15 km buffer zone. The project is located in Korba, which is one of the critically polluted areas in the country. Open, mixed forest is found in the core and buffer zone. A large number of high-capacity mines are situated in the vicinity of the project. The project involves R&R of 10 villages from the existing (20 MTPA) project– Sirki, Chainpur, Suwabondi, Jhingatpur, Malgaon, Beltikri, Dipka, Jhabar, Ratiza, and Renki involving 1690 PAFS of which 1471 PAFS have been rehablitated. The expansion project involves additional R&R from 5 villages comprising a total of 903 PAFs – Renki, Suwabondi, Hardibazar, Malgaon and Amgaon.


Maximum rated capacity of the mine is 25 million tonnes per annum (MTPA) of coal production. Mining will be both opencast (OC) be mechanised method using surface miner for coal extraction and shovel-dumper for OB removal. Blasting is limited to OB removal. Of the total lease area, 1002.053 ha is for quarry area, area for storage of topsoil is 5 ha, area for ext. OB dumps 206 ha, mineral storage area is 3 ha, roads 4 ha, green belt 15 ha, safety zone 111 ha, infrastructure & other facilities such as CHP 614.589 ha and RR site of 40 ha outside the ML. A township of an area of 35 ha with 1287 dwelling units is established at a distance of 2 km form ML. Entire mineral transportation of 600606 TPD of coal from mine pit top to railway siding being established within the ML area is proposed to be by closed conveyors and thereafter by rail/MGR. Loading would be mechanised by Silo Loading System. Ultimate working depth of the mine is 280 m below ground level (bgl). Present working depth is 90m bgl. Water table is in the range of 6.57-8.21 m bgl during pre-monsoon and 3.78-4.49m bgl during post-monsoon. Peak water demand is 4135 m3/d of water of which 1925 m3/d is for dust suppression, 200 m3/d is for domestic consumption, 150 m3/d is for green belt, 360 m3/d is for CHP, 250 m3/d for workshop, and balance in township and other uses. Of the total water demand, 885 m3/d would be met from River Hasdeo, 650 m3/d is groundwater and 2600 m3/d is from mine water. An estimated 615 Mm3 of OB would be generated over the balance life of the mine, of which 534 Mm3 would be dumped in decoaled void of 780 ha and the balance 81 Mm3 of OB would be stored in external OB dump of 206 ha of a max. height of 90m from ground level.  Backfilling would begin from 16th year of expansion project.  Of the 1002.053 ha of the quarry area,  an area of 780 ha would be reclaimed with vegetation and the balance 222.053 ha would be left as a void/water body for further expansion in the dipside. Life of the project at the rated capacity of 25 MTPA is 25 years. Capital cost of the project is Rs. 1843.48 crores. Mining Plan of the project was approved by the Ministry of Coal on 20.12.2006. Public Hearing was conducted on 05.09.2008.
