The optimization of mining methods is a kind of typical multi-objective decision problems.Its results directly effect mining operations and related engineering construction, even the economic benefits.In order to guarantee the sustainable development of a certain copper mine, transferring from open pit into underground mining, a comprehensive evaluation of three primary selected mining methods was carried out from the view of system engineering.Six indicators were overall considered by analytic hierarchy process, and their weight were defined scientifically and reasonably to establish index weight matrix.Simultaneously, a fuzzy relation matrix, indicating the fuzzy relationship between mining methods and indicators, was also established by applying fuzzy comprehensive evaluation method.Finally, comprehensive feudatory degrees of the three mining methods could be obtained by combine the index weight matrix and fuzzy relation matrix.Then, the mining methods can be ranked according to the value of comprehensive feudatory degrees.The ranking results show that double room and pillar method is the most suitable for underground mining of the copper mine.%采矿方法的优选作为一种典型的多目标决策问题,其结果直接影响到地下采矿作业及相关工程建设,甚至是矿山的最终经济效益.针对某铜矿山即将由露天转向地下的开采现状,为保证其安全高效地可持续发展,从系统工程的角度对初选出的3种采矿方法进行综合评价.应用层次分析法综合考虑6种主要技术经济指标,并采用3标度法较科学合理地确定各指标权重,建立指标权重矩阵.同时,应用模糊综合评价法确定出采矿方法与各指标之间的模糊关系,并建立模糊关系矩阵.最后,将指标权重矩阵与模糊关系矩阵相结合,得到采矿方法关于各指标的综合隶属度.根据综合隶属度的大小,即可对采矿方法的优劣进行排序.排序结果表明,双上山房柱法为最适用于该铜矿山地下开采的采矿方法.
