摘　　要：基础的L-G图论法未考虑地下开采可能的成本优势,在露天转地下矿山开采境界圈定时存在一定的局限性。本文通过对价格法与储量盈利比较法计算的经济合理剥采比进行分析,结合NPV Scheduler软件研究了露天转地下开采境界圈定方法,并通过工程实例验证了该方法的合理性。研究成果对露天转地下矿山开采境界的确定具有一定的指导意义。The basic L-G graph theory does not take into account the possible cost advantages of underground mining,and there are certain limitations in the boundary optimization of open-pit to underground mining.Based on the analysis of the economic and reasonable stripping ratio calculated by the price method and the reserve profit comparison method,and combined with the NPV Scheduler software,this paper studies the method of boundary optimization of open-pit to underground mining,and verifies the rationality of this method through engineering examples.The research results have certain guiding significance for the determination of mining boundary of open-pit to underground mines.
