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.
基于數字礦床模型中的塊體模型,在給定的境界內,利用錐體排除法產生一繫列地質最優開採體,建立動態規劃模型,以淨現值最大為目標函數,應用動態規劃法對最優開採體進行動態排序,就可以找到最優開採路徑作為最優開採方案. 將上述方法應用于某露天礦,得齣礦區的最佳開採年限為15 a,併給齣瞭每年的開採區域、採礦量、剝巖量以及年末的纍積淨現值.

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.
