Coal mining authorities of North Eastern Coalfields have been facing serious challenges of reclamation of the mine lands and restoration of natural ecosystem as a result of opencast mining operations on densely forested hills In Assam. Having regard to present operations, locations of opencast mining and particularly importance of Assam Coal and its potential use In steel industry and environmental restoration/ reclamation treasures taken by the NEC authorities, it is justified to continue present opencast mining cperations. This case study attenpts to present sincere efforts being carried out in environmental restoration by NEC authorities. Background of mining, geology, climate and ecology in the region and also Impacts of opencast mining operations have been described in this paper. Slope stability and aspects of control of soil wash off are also dealt with particularly civil engineering and mechanical measures such as terracing. bamboo barricading in the slopes, stone-barriers at the toe of dumps. revetment and retaining walls. Check-dams in the channels and valleys and gully-plugging etc. Vegetation restoration through plantation of various selected species Including turfing/transplantation etc are also presented. Solt quality aspects of In-situ soils dealt with. Vegetation results obtained have been quite successful with survival of diverse species at the rate of over 90%. The aspects of restoration of natural ecosystem restoration in this region of subtropical climate have also been described. |
