针对国内某地下金属矿山的资源状况和开采条件发生了重大变化,现行产能过大而急需重新审视和适当调整生产能力的实际情况,综合运用地下矿山经济寿命计算泰勒公式及产能计算公式获得与矿山现实资源状况相适应的合理产能范围；根据矿山开采技术经济条件与可持续发展两大因素分析确定影响矿山产能的主要决策目标；在运用熵权法及两两对比法计算获得目标权重的基础上,采用综合集成赋权法确定更合理的权重系数；运用灰色局势决策法实现矿山生产能力的优化.研究结果表明:优化结果符合矿山的生产实际,可作为矿山资源开采规划和生产计划编制实施的依据.%According to the fact that the resource status and exploration condition of a domestic underground metal mine change greatly and the current productivity is too large which urgently needs re-examination and proper adjustment of production capacity, by comprehensively using the taylor calculation formula of underground mine's economic life and production capacity calculation formula, the reasonable productivity range in accordance with the mine's real resource status was obtained. Based on the analysis of two factors, i.e. mining technical and economic condition and sustainable development, the major decision-making target which influenced mine productivity was determined. Based on the obtainment of objective weight by using entropy method and pairwise comparative method, more reasonable weight coefficient was determined by using combination weighting method. Finally, optimization of the mine production capacity was achieved by using grey situation decision. The results show that the optimizing result is constant with the practice and can be used as the decision-making basis for the establishment and implementation of mine resource exploration and production plan.
