J-11015/245/2011-IA-II.(M) dated 21.07.2015, the cluster consisted of 8 (eight) underground mines and 3 (three) mixed mines. The capacity of the cluster was 10.90 MTY in a leasehold area of 4218.0 Ha. However, in view of the revised production targets set by CIL, a re-assessment of mine capacities has been carried out for the cluster while keeping the overall cluster area unchanged. This re-assessment / rationalization has been done based on present condition and capability of the mines for achieving optimum production levels. The re-organization of UG and OC mining has been planned with due regard to environment. Based on the approved Revised Mining Plan of the cluster, EC Amendment was granted vide even letter no. dated 29.11.2016. In the amendment, the capacity of the cluster is reduced from 10.90 MTY to 8.20 MTY keeping the overall cluster area same. The mines of Cluster No. 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 mines are administratively under Kenda and Bankola Areas of ECL.

Krishnanagar UG At present, there is no production from the mine. 2. Haripur OC At present, production from the mine has been temporarily suspended. 3. Chora Block Incline In Chora Block Incline mine, extraction of coal is being carried out in R-VII seam. Method of mining adopted is Bord& Pillar method and at present development of pillars is going on. SDLs are deployed for loading of coal into mine tubs. Loaded coal tubs are transported belowground by combination of tugger and endless haulages to feed the main haulage for final transport to the surface. 4. Chora 7, 9 & 10 Pit In Chora7 & 9 Pit, R-VI seam is being worked in 2 sections. The already developed bottom section is being depillared (splitting as final operation) and hydraulically stowed. The top section is being developed over sand to be depillared subsequently. In total 4 SDLs are deployed for loading of coal into mine tubs. In Chora-10 Pit mine, extraction of coal is being carried out in top section of R-VI seam. Method of mining adopted is Bord & Pillar method and at present depillaring of pillars are being carried out in conjunction with hydraulic sand stowing. In total 2 SDLs are deployed for loading of coal into mine tubs. In both units, loaded coal tubs are transported belowground by combination of tugger and endless haulages to feed the winding system for final transport to the surface. 3 Environmental Statement (Form-V) for Cluster No. – 11 (Group of Mines) 2019-20 5. Bonbahal OC Patch The conventional shovel – dumper combination is being used for coal production and OB removal. The OC patch involves extraction of two seams namely, R-VII and R-VIIA seams, which had been worked in past by underground method in different patches of the proposed zone of work. 6. Shankarpur / CL Jambad OC Patch/ mine The conventional shovel – dumper combination is being used for coal production and OB removal. The OC patch involves extraction of the R-VIII seam only which is developed / de- pillared within the proposed zone of work. The access trench for the proposed OC patch will be made through the old de-coaled area of Shankarpur/CL Jambad OCP. Virtually, the proposed OC patch is an extension of old OC patch. 7. New Kenda UG & OC Patches/Mines In New Kenda UG mine, extraction of coal is being carried out in R-VI seam. Method of mining adopted is Bord & Pillar method and at present depillaring of pillars (splitting as final operation) is being carried out with hydraulic sand stowing. In total 2 SDLs are deployed for loading of coal into mine tubs. Loaded coal tubs are transported belowground by combination of tugger and endless haulages to feed the winding system for final transport to the surface. Conventional shovel-dumper system of mining is proposed for both the mines/patches. The New Kenda OC involves extraction of three seams namely, R-VIIB, R-VI and R-V seams, which have already been developed/partially depillared by New Kenda UG. The OC patch envisages to work a part of these seams falling within the leasehold area of New Kenda Colliery. At present, there is no production from West Kenda OC Patch. 8. Bahula Group of Mines a) Lower Kenda UG In Lower Kenda UG mine, extraction of coal is being carried out in R-V Seam. The method of mining adopted Bord and Pillar method of mining. At present development of pillars is underway in one Panel and in another Panel depillaring is being carried out with sand stowing. Coal loading is being done by the use of SDLs. Transportation of coal is effected by means of tugger and endless haulages. Coal from the underground coal face is hauled by combination of endless and tugger haulages to feed the winding system through which coal tubs are raised up to the surface. b) Bahula UG Several workable seams occur within the project area of Bahula colliery. However, at present, Kenda seam and Bonbahal seams are being worked in Bahula UG mine through three working units in the following manner: a. In Bonbahal seam (R-VII) at RJ Unit, one SDL district through No. 1 Pit is being depillared by slicing with hydraulic sand stowing. b. In Kenda seam (R-VI) at PJ Unit, one district through No. 6 Pit is being depillared by splitting as final operation method with hydraulic sand stowing.
