印度目前的矿物总产量为2.5亿吨,预计2000年将生产6亿吨,这将要求表土和废石的剥离量从目前的4.5亿吨增加到24亿吨左右。露天采煤的比重将从“六·五”计划的49%增长到“匕·五”计划的56%,开采深度达300~400米,剥采比为4~5。库德雷穆克铁矿设计年产量为2250万吨,马兰杰坎德铜矿在90年代可能扩大到年产矿石1000万吨,剥离废石4000万吨。这些巨型矿山的设
India’s current total mineral production is 250 million tons and it is expected that 600 million tons will be produced in 2000, which will require the amount of topsoil and waste rock stripping to increase from the current 450 million tons to about 2.4 billion tons. The proportion of open-cut coal mining will increase from 49% of the “June 5” plan to 56% of the “Daguan · 五” plan with a mining depth of 300 to 400 meters and a stripping ratio of 4 to 5. Kudelekeke iron ore design annual production of 22,500,000 tons, Malanjie Kande copper mine in the 90s may be expanded to an annual output of 10 million tons of ore, peel 40 million tons of waste rock. These giant mines are set
