| 摘 要： | 以计算机实现移动圆锥的境界优化方法为基础，计算不同边界品位条件下的矿床模拟开采数据，分析得出盈亏平衡法确定边界品位的方法不能使矿山企业的总盈利最大，合理的边界品位应该低于盈亏平衡品位的结论。采用合理的边界品位不仅能扩大矿山企业的总盈利，而且能够充分利用矿产资源。

| Abstract: | On the basis of computerization of the optimization of open pit limit by moving cone,the data of simulated exploitation is computed with different cut-off grades.With the analysis,the conclusion is that cut-off grade which is defined by breakeven method don't bring the greatest profit for the mine enterprise,and that rational cut-off grade is lower than breakeven grade.In this way,the mine enterprise not only increases the total profits but also makes full use of the mineral resources. |
