摘要: 在露天煤矿设计及矿区总体规划中,通过钻孔剥采比等值线来圈定露天矿开采境界是大家采用的普遍方法。但事实上,已经存在总体规划所划定的露天矿范围在实际中无法开发的情况。文章从定义出发,通过规范规定、相关示例,层层深入分析露天矿剥采比在设计中的重要性。最后通过特殊示例分析论证钻孔剥采比在应用中的局限性需引起重视,文中的特例对露天煤矿设计中圈定境界及矿区总体规划中划定矿田范围具有重要的指导意义。

Abstract: In open-pit design and overall planning, it is the common methods that everyone delimit open-pit mining boundary through drilling stripping ratio contour. But in fact, there have some open-pit area cannot be developed economically which designated by the overall planning. In this article, first starting from the definition, then through the regulation of standard and some example, analyzed the importance of stripping ratio in open-pit mining design. Finally analyzed drilling stripping ratio have some limitations and should be taken seriously attention. The special cases in this article are important guiding for setting boundary of open-pit design and designating limits of overall planning.
