摘　　要：针对贵州开阳磷矿东翼矿区井下微震监测系统台网布置方案的优选问题,基于国内外学者在台网优化布置时所选参数指标,对微震监测台网在建设、运行和维护阶段的需求进行分析,确定多个台网布置方案的静态、动态和定量、非定量指标构建综合评价指标体系。通过熵权法给出各评价指标的客观权重向量,基于模糊数学原理建立模糊综合评判模型,对初选出的五个台网布置方案进行分析,求解出各方案的综合优越度,最终确定并推荐方案二(综合优越度为0.796)为最优方案。模糊综合评价模型能够较准确地确定适用于矿山需求的微震监测台网方案,对矿山微震监测系统的建设具有指导意义。In the process of ascertaining the optimal layout scheme for the underground micro -seismic monitoring system net-work in the east flank mining area of Kaiyang Phosphorite Mine in Guizhou , based on the parameters indexes chosen by do-mestic and foreign scholars during the optimizing of network layouts , the requirements in the construction , operation and ma-intenance stage of the micro-seismic monitoring network were analyzed , and a comprehensive evaluation index system was es-tablished by determining the static and dynamic , quantitative and non-quantitative indexes of multiple network layout schemes .The objective weight vectors of each evaluation index were determined by entropy weight method , and a fuzzy com-prehensive evaluation model was built based on the fuzzy mathematics principle .After the analysis on five primary network layout schemes , the comprehensive superiority degrees of each scheme were obtained , and the scheme Ⅱ with the compre-hensive superiority degree of 0.796 was determined and recommended to be the optimal scheme .The fuzzy comprehensive e-valuation model can determine the micro-seismic monitoring network scheme meeting the requirements of mine more accurate -ly, and it is an important guidance for the construction of the micro-seismic monitoring system in mine .
