6 Singrauli Coalfields (SC) 14,873 hectares for 10 mining blocks44.4% for mining excavation12.2% for overburden dumps17.0% for infrastructure26.4% for other operationsEnvir. ManagementExternal dumping area is kept to a minimum.Dragline, shvel-dumper combination and dozers are for filling purposesPeriphery of overburden dump slope kept an angle of 28°Height no more than 30mResultsSeveral species of plants grown on overburden dumps (Dep. Botany, Banaras University)
7 (Bharat Aluminum Co. Ltd.) Amarkantak BauxiteMines (ABM) – SSM(Bharat Aluminum Co. Ltd.)Reclamation ProgrammeReclamation work started in 1979Void areas filled with lateritic overburdenAnd covered with top soil layerRestored land > 150 ha18-20 ha/year reclaimed with aprox. 60,000 trees of 52 speciesIt is possible to reclaim them through crop cultivation andSmall appropriate dose of NPK fertilizers
8 4. Central Mining Research Institute (CMRI) Amjhore Pyrite Mine (APM)Acid Mine Drainage most serious problemShales excavated contains in dilution until 22% sulphurMaterial from excavations are aprox. 0.3 TonsIn rainy season increases the acidity of the soilHigh acidity affects the revegetation process.EnvironmentalImpactsCMRISuccessfully revegetation processwas obtained using lime,phosphatic waste, and industrialcinders.It works!
9 5. Planning for ClosureSource: Environmental Policy in Mining, A. Warhurst
10 6. Constraints and Opportunities Developing CountriesLack of infrastructure and resources.Ineffective information technologyPolicy failuresPolitical barriersLack of monitoring and controlIndiaMulti-disciplinary HR.Infrastructure facilities.Well-recognized R&D facilities.
11 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.
