6. 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)

Reclamation Programme
Reclamation work started in 1979
Void areas filled with lateritic overburden
And covered with top soil layer
Restored land > 150 ha
18-20 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

8. 4. Central Mining Research Institute (CMRI)
Amjhore Pyrite Mine (APM)
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.
Environmental
Impacts
CMRI
Successfully revegetation process
was obtained using lime,
phosphatic waste, and industrial
cinders.
It works!

10. 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.

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.
