-
摘要: 探討了臺階高度對露天開采的影響,并以礦巖運輸成本,運輸道路的修建、維護費,臺階維護、清掃費的綜合貼現值最小為原則,研究了臺階高度的合理值。Abstract: The effect of bench height on open pit mining is studied.The rational bench height is proposed on the principle of that the comprehensive present value of transportation cost, maitaining and building transportation road cost and maintaining final wall bench cost is minimum.
