摘要
以工程设计实例为依据,论述了露天开采经济合理剥采比的计算方法和适用条件.分析和探讨了支建煤矿经济合理剥采比计算方法,原矿盈利比较法、原矿成本比较法计算出来的经济合理剥采比分别为20.3m3/m3、26.9m3/m3,取整后以20m3/m3 作为矿床经济合理剥采比指标.
Abstract
Based on engineering design examples,this paper discusses the calculation method and applicable conditions of economic stripping ratio for open-pit mining.The calculation methods of economic stripping ratio of Zhijian Coal mine are analyzed and discussed.The economic stripping ratio calculated by the profit comparison method of raw ore and the cost comparison method is 20.3m3/m3 and 26.9m3/m3 respectively,and 20m3/m3 is taken as the index of economic stripping ratio of the ore deposit.
