The mines are administratively under Kenda and Bankola Areas of ECL. The mines of Cluster-11 are located in the east central part of Raniganj Coalfields and north of the Damodar River in the Burdwan District of West Bengal and are having lease boundaries adjacent to one another. The Cluster is located within Latitudes 230 38’ N & 230 41’ N and Longitudes 860 46’ E & 860 51’ E lying 100m to 140m above MSL. The cluster was awarded EC vide letter no. J-11015/245/2011-IA-II.(M) dated 21st July, 2015 with following cluster mine details: S.

Krishnanagar UG Production in the mine has been discontinued since 1989-90 due to adverse geo-mining conditions – mainly waterlogging and high concentration of gases. However, it is being planned to exploit the virgin Koithee (R-III) seam. Considering the unexploited reserve still remaining in R-III, it is being planned that dewatering and degasification of the mine and subsequent mining will yield coal of C-D grade in substantial quantity. The project has the capacity to yield a normative capacity of 0.24 (MTY) and a peak capacity of 0.30 (MTY) by exploiting the lower virgin horizons. It is proposed to exploit the same accordingly. 2. Haripur UG At present, production from the mine has been temporarily suspended. Haripur Colliery is working in Dobrana seam only. The total mineable reserve is 16.40 MT out of which 10.64 MT is virgin and 5.76 MT is standing on pillar. The gradient of the seam is 1 in 10 and the degree of gassiness of the mine is Degree- II. It is expected that by introducing additional CM and additional SDL, production will be increased. 3. New Kenda UG & OC Patches At present, Dobrana and Kenda seams are being worked in this mine. Two districts are running in the mine – one manual depillaring district with hydraulic sand stowing in Dobrana seam and another also manual depillaring district with hydraulic sand stowing in Kenda seam. Two OC patches have been identified for opencast mining, details of which, are given as under – Sl Name of Mine Area(Ha) Mineable Peak Volume of Life N Reserves Capacity OB to be in (MT) (MTY) generated years (Million M3) 1 W Kenda OC Patch 49 1.18 0.75 7.65 2 2 New Kenda OC Patch 240 22 3.90 211 8 4. Lower Kenda UG At present, Dodrana seam is being worked in this mine through No. 4, 6 and 7 Pit. Depillaring district alongwith hydraulic sand stowing is going on at No. 4 Pit. Manual development by Bord & Pillar Method is going on at No. 7 Pit and development with SDL is in progress at No. 6 Pit. 3 Environmental Statement (Form-V) for Cluster No. – 11 (Group of Mines) 2015-16 5. Chora 7, 9 & 10 pits UG At present, Chora seam is being worked in this mine. Two districts are running in the mine – one development district (S2, top section) with SDL over standing bottom section and another depillaring district (S3, bottom section) with sand stowing in the bottom section working with LHD. 6. Chora Block Incline UG & OC Patches At present, Chora seam is being worked in this mine. The seam is already developed by Bord & Pillar Method upto a height of 3 m along floor almost upto the mine boundary. The pillars in this section are going to be extracted upto a height of 3.60 m along floor by splitting and sand stowing. The remaining top section will be developed upto 3 m over sand and will be splitted upto a height of 3.60 m over sand and will be filled up with sand stowing. At present, two districts are running in the mine – one development district with two SDLs over sand and another manual depillaring district with sand stowing. Water spraying is going on in both the district. Two OC patches have been identified for opencast mining, details of which, are given as under – Sl Name of Mine Area Mineable Peak capacity Volume of OB to Life in No (Ha) Reserves (MTY) be generated years (MT) (Million M3) 1 Bonbahal OC Patch (25ha) 25 1.1 0.50 6.27 3 2 Shankarpur/CL Jambad OC Patch Exhausted and being backfilled 7. Bahula UG At present, Kenda seam and Bonbahal seam are being worked in this mine. In Bonbahal seam at RJ Unit one SDL district through No. 1 Pit is being depillared by splitting as final operation method with hydraulic sand stowing. In Kenda seam at PJ Unit one manual district through No. 6 Pit is being depillared by splitting as final operation method with hydraulic sand stowing. In Kenda seam at NJ Unit two SDL districts through No. 3 Pit is being depillared by splitting in bottom section and slicing in top section with hydraulic sand stowing. 8. C L Jambad UG At present, Jambad seam is being worked in this mine. The seam is already developed by Bord & Pillar Method and now one manual district is being depillared by splitting with hydraulic sand stowing. 9. Siduli UG The mine block has been taken within the faults F3-F3, F4-F4, F10-F10 and Chora block on the North-Western side. The existing constituent within the above block are Siduli colliery comprising J.K.unit and Siduli unit, Nags Kajora unit of Khandra mine. R-IX seam has been worked in Nags Kajora unit where the seam has incropped and has been abandoned. R-VIII seam has been extensively worked in the J.K.unit (R-VIII seam exhausted) and Siduli unit of Siduli colliery and Nags Kajora unit of Khandra colliery (R-VIII seam near exhaustion). R- VIII seam is exhausted in Pure Seetalpur unit, Khas jambad unit and Seetalpur unit.
