3. Best Practice for Mine Closure Environmental Policy in Mining, A. Warhurst Source: Environmental Policy in Mining, A. Warhurst
Singrauli Coalfields (SC) 14,873 hectares for 10 mining blocks 44.4% for mining excavation 12.2% for overburden dumps 17.0% for infrastructure 26.4% for other operations Envir. Management External dumping area is kept to a minimum. Dragline, shvel-dumper combination and dozers are for filling purposes Periphery of overburden dump slope kept an angle of 28° Height no more than 30m Results Several species of plants grown on overburden dumps (Dep. Botany, Banaras University)
Amarkantak Bauxite Mines (ABM) – SSM (Bharat Aluminum Co. Ltd.) Reclamation Programme Reclamation work started in 1979 Void areas filled with lateritic overburden And covered with top soil layer Restored land > 150 ha ha/year reclaimed with aprox. 60,000 trees of 52 species It is possible to reclaim them through crop cultivation and Small appropriate dose of NPK fertilizers
4. Central Mining Research Institute (CMRI) Acid Mine Drainage most serious problem Shales excavated contains in dilution until 22% sulphur Material from excavations are aprox. 0.3 Tons In rainy season increases the acidity of the soil High acidity affects the revegetation process. Amjhore Pyrite Mine (APM) Environmental Impacts CMRI Successfully revegetation process was obtained using lime, phosphatic waste, and industrial cinders. It works!
5. Planning for Closure Environmental Policy in Mining, A. Warhurst Source: Environmental Policy in Mining, A. Warhurst
6. Constraints and Opportunities Developing Countries Lack of infrastructure and resources. Ineffective information technology Policy failures Political barriers Lack of monitoring and control India Multi-disciplinary HR. Infrastructure facilities. Well-recognized R&D facilities.
7. Conclusions & Recomendations Environmental considerations at every stage. Good understanding of resource deposits and rehabilitation philosophy. Water treatment of mine discharges. Considering of Environmental Policy Reforms. International Agencies co-operation improves the process of clean technology transfer.
