INNOVATIONS OF DEEP OPENCAST MINING WITH SUSTAINABILITY
Binay Kumar Samanta*
ABSTRACT
The operating cost of mechanized opencast mines has escalated with an increase in prices of essential inputs, like materials, spares, haul-road maintenance, spiraling wages, and improved welfare facilities to employees. The Coal vision 2025 of India estimates that the total domestic coal production is projected to increase to 1086 MT in 2025, of which the opencast production will be 902 MT (83%). In India mining areas are also populated, restricting the boundaries of quarries. So quarry-bed Crusher linked to properly designed steep elevator, loading into a quarry-top bunker for truck loading or conveyor transport to the siding/consumer. A coded computer program model, in Java with cost and technical data of small quarries of a coal company, with program run ?troq? which showed quite appreciable cost benefits with steep transport. Many other innovations are outlined and there are choices of equipment suppliers now. The research in ECL, & BCCL, subsidiaries of Coal India shows that fire and unsystematic underground mining need deep opencast mining. The objective of the paper is the continued viability of opencast mining.
