摘要
经济剥采比是确定露天矿境界的重要因素．指出了经济剥采比的计算过去没有考虑资金的时间价值，而且采用了“矿井优先”的错误原则．在此基础上，提出了当量经济剥采比的新概念，既考虑了回采率和安全性两个主要因素，又体现了“露天优先”的正确原则．建议将确定露天矿境界的原则修正为：境界剥采比小于等于当量经济剥采比．
Economic stripping ratio is an important factor for determining the limit of open pit mines. It is pointed out that in the past the economic stripping ratio was calculated on the basis of a wrong principle, “priority of underground mining, ” and without taking the time of investments into account. A new concept, equivalent economic stripping ratio, is put forward, which not only considers both main factors——the mining rate and the safety, but also reflects a correct principle, “priority of surface mining” . The principle for determining the limit of openpit mines, i.e. the limit stripping ratio should be less than or equal to the equivalent economic stripping ratio, is advanced.
