基于矿岩运费的深凹露天矿合理台阶高度探讨

Study of the Rational Bench Height of Deep Open Pit Mines Based on Transportation Cost

    摘要
  • 摘要: 探讨了台阶高度对露天开采的影响,并以矿岩运输成本,运输道路的修建、维护费,台阶维护、清扫费的综合贴现值最小为原则,研究了台阶高度的合理值。

     

    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.
