Sub: Khagra-Joydev Block Opencast Coal Mine Project (3 MTPA) of M/s
DVC Emta Coal Mines Ltd., located in Block Dubrajpur, district Birbhum, West
Bengal - environmental clearance ? reg.
Sir,
This has reference to your letter No. DVC
EMTA/MoEF/KJ/2006/30 dated 14.10.2006 along with your application for Terms of
Reference (TOR) and this Ministry?s grant of TOR vide letter dated 27.12.2006
and your letter dated 23.02.2009 along with your application for environmental
clearance based on TOR and subsequent letters dated 29.04.2009 and 04.06.2009
on the above-mentioned subject. The Ministry of Environment & Forests has
considered your application. It is
noted that the project is for opening a new Khagra-Joydev Opencast Coal
Mine Project of 3 MTPA production
capacity for captive use of its
Mejia (Extension) Thermal power plant, Gangajhalgati and Durgapur TPP, both
located in West Bengal. The total
land requirement (project area) is 1215.24 ha allotted for both opencast and underground mining. The present project seeking environmental clearance is for opencast
mining only. Of the total
project area, 814.34 ha is
agricultural land, 285.60 ha is forestland, 44.58 ha is surface water bodies,
and 82.88 ha is others (including safety zone). Forestry clearance has been
applied for. River Ajoy and its tributary namely River Hingla and River Kana
flow along the eastern boundary of the block. The project involves modification
of the natural drainage by diversion of River Hingla flowing within the lease
and the diverted river to join with River Kana. The mine is at a lower level
(67m RL) as compared to that of River Hongla (72m RL). It is also proposed to
construct an embankment along the river Ajoy 5m above HFL and along Rivers
Hingla and Kana on both sides to prevent mine inundation and maintain the river
course. The schedule of construction of embankment is 2 years. The present project is however for opencast
operations only of which 903.61 ha is quarry area. Some land bordering the block is being acquired for the
purpose of creation of ext. dump (126 ha), topsoil dump (36.30 ha), temporary
ext. sand dump (20 ha), infrastructure including colony and R&R site (36
ha), and safety zone (120 ha) as part of project area which together with the
quarry area of 903.61 ha would comprise the total project are of 1215.24.
Mining
will be opencast by mechanised method using surface miners for coal extraction;
however, OB removal would involve blasting.
The rated capacity of the mine is 3 MTPA of coal production would be achieved
by 4th year. No ancillary operation such as mineral processing is
involved. Mineral transportation of 9000 TPD of coal to coal washery would be
by belt conveyors of a length of 4.5 km. Ultimate working depth of the mine is
160m below ground level (bgl). Water table is in the range of 2-11.7m bgl
during post-monsoon. Mining will intersect water table. Peak mine water
discharge is estimated as 1200 m3/d. An estimated 643.56 Mm3 of wastes
including OB will be generated during the life of mine of which 10 Mm3 would be
topsoil, which would be used for green belt development. About 60 Mm3 of OB
would be stored in one external OB dump of a maxm. of 60m height over an area
of 126 ha and the balance 336.56 Mm3 of OB would be backfilled in a decloaed
area of 762.28 ha and raised to a height of 20m above ground level and
reclaimed with plantation leaving a void of 88.30 ha which is to be converted
into a water body. Backfilling would begin from 2nd year and
concurrent backfilling from 16th year. Project involves R&R of
10 villages ? Devipur (8), Joplai (70), Jhirul (6), Palashdanga (63), Loba
(78), Barari (36), Khojkamalapur (85), Kota (177), Birbhadrapur (8), Kamalapur
(8) consisting of 539 PAFs (2986 PAPs), which would be undertaken in phases. A
site for resettlement colony has been identified. Public Hearing was held on
25.11.2008. Mining Plan has been approved by Ministry of Coal on 0310.2006.
Life of the mine is 37 years at 3 MTPA rated capacity. Capital cost of the
project is Rs. 435.75 crores.
2. The Ministry of Environment &
Forests hereby accords environmental clearance for the above-mentioned Khagra-Joydev Block Opencast Coal Mine
