摘要： 基于浮锥排除法原理以及柱状煤层模型，在已知境界中产生地质最优采场序列.建立动态排序模型，以净现值最大为目标函数，用动态规划方法找出最优开采路径作为最优开采方案，实现开采顺序、生产能力及开采寿命三大要素的同时优化.将上述方法应用于某露天煤矿得出，该矿山开采时间为39年，年生产能力为1649万t，不考虑基建投资的生产净现值为33998亿；同时给出了每年岩石及表土剥离量和具体的开采位置，为矿山生产决策者提供了有力手段.

Abstract: Based on the floatingcone exclusion method and geological model of coal seam， geologically optimum pushbacks were produced in a known final pit of coal mine. A dynamic sequencing model was established and the geologically optimum pushbacks were introduced into it， with the maximum NPV (net present value) as a target function. Then the best mining path of final pit was found out as an optimal mining scheme， thus the mining sequence， production capacity and mining life regarded as three essential factors of production schedule were simultaneously optimized. A case study on an openpit coal mine shows that the mining life is 39 years， annual production capacity is 1649 million tons and the NPV is 33998 billion RMB without capacity investment taken into account. At the same time， rock and topsoil annual stripping volume as well as working face in each year are given out， which provides powerful tools for decisionmakers.

Key words: openpit coal mine, geologically optimum pushbacks, production schedule optimization, dynamic programming, floating cone method
