Based on the block model among the digital deposit models,and within a given region,the cone solution meth-od was used to produce a series of optimal geological pits,and establish the dynamic programming model. With the maximized net present value as target function,the dynamic programming method was adopted to make the dynamic sequencing on the op-timal pit. The optimal mining path can be chosen as the optimal mining scheme. Application of this scheme into a certain open-pit mine shows that its best service life is 15 years,and the annual mining area,mining amount,stripping quantity of rock,and the cumulative net present value at the end of each year are given respectively.%基于数字矿床模型中的块体模型,在给定的境界内,利用锥体排除法产生一系列地质最优开采体,建立动态规划模型,以净现值最大为目标函数,应用动态规划法对最优开采体进行动态排序,就可以找到最优开采路径作为最优开采方案. 将上述方法应用于某露天矿,得出矿区的最佳开采年限为15 a,并给出了每年的开采区域、采矿量、剥岩量以及年末的累积净现值.
