摘要

Mining is one of the most destructive activities to the nature.In the open cast mining method,the environment degrading activities starts right from the clear felling of the area for mining and the allied activities. The degradation of mining area increases with the increase of intensity of operation.Coal deposit is having stripping ratio of 2:1(overburden:ore)and open cast mining method is adopted in India to a depth of 200 meters.In the forth-coming years,it is foreseen that coal deposits having a stripping ratio up to 7：1 and extending to a maximum depth of 480 meters will be mined.In the coming years India will have to handle 1150 million cubic meters of overburden per year for producing 230 million tons of coal, anticipated through the opencast minmg. The physical nature of waste is often inimical to plant growth;the mining areas are characteristically barren,sterile, devoid of vegetation and lacking topsoil to support vegetation.Surface stability of barren land is of paramount importance in areclamation program,more so,when the wastes are fine,conditions are arid and erosion is likely.Vegetation is the only method of achieving long-term stability. The natural colonization of vegetation is very slow and leaving the area prone to soil erosion which opined by various researchers. The reclamation through the artificial means is the suitable option to develop the vegetative cover in comparatively less time. The biological reclamation effort,which was initiated in the year 1993 basically,focused to analyze the natural succession in coal mine overburdens of the Bisrampur colliery of Surguja district of Chhattisgarh and developed a comprehensive technological package for the reclamation of coal mine overburdens. In the era of globalization the developmental activities cannot be checked in light of the conservation efforts.However,there is a strong need to develop/adopt suitable monitoring mechanism to meet the conservation goal without adversely affecting the pace of development. The present study will help in evolving indicators for land rehabilitation and sustainable development.
