露天煤矿开采计划的整体动态优化

针对新建或扩建露天煤矿，给出了一个能够同时求得最佳生产能力、采剥顺序和生产寿命的动态优化方法.该方法首先对所研究的矿床建立煤层数字模型，基于这一模型，在最终境界内产生一个“地质最优开采体”序列，然后把序列中的开采体作为状态建立动态规划排序模型，对所有可行的子序列进行经济评价，得出总净现值最大的子序列，这一最佳子序列同时给出了每年的煤炭开采量和剥离量、采剥推进位置与生产寿命.

Overall dynamic optimization of production schedule in open-pit coal mines

For a new open-pit coal mine or an existing one for which production expansion is being considered,a dynamic optimization method was developed and presented that is capable of giving simultaneous optimum solutions to production capacity,mining sequence,and mine life.The method first established numerical model for the coal deposit.Then,a series of "geologically optimum push-backs" was generated based on the numerical model.The geologically optimum push-backs were put into a dynamic sequencing scheme and wer...
