摘　　要：通过分析资金的时间价值因素对露天境界经济效果的影响,提出一种露天境界与分期开采相结合的优化思路。在静态境界优化结果的基础上,分析分期开采的可行性,选择合理的分期境界,利用程序计算出净现值,根据净现值最大准则选择最优境界。The author has analyzed the influence of time value factor upon economic effects of the open pit boundary and thus put forward an optimization idea to combine the open pit boundary and mining by stages. Based on the results of static pit optimization, the author has analyzed the feasibility of mining by stages, selected the reasonable boudaray limit stages, calculated the NPV with software, and selected the optimal boundary limit to maximize the NPV.

关 键 词：境界优化 分期开采 净现值
