摘　　要：为了降低煤矿生产风险、及时预测和控制巷道冒顶风险,选取巷道稳定岩层厚度、地质条件、巷道断面形状等12项评价指标,构建巷道冒顶风险评价指标体系,提出了巷道冒顶的风险程度标准;采用层次分析(AHP)法和熵权(EW)法组合权重物元可拓理论建立了巷道冒顶风险评价模型,根据最大隶属度原则确定了巷道冒顶的风险程度;并基于JavaWeb开发了巷道冒顶风险评价系统(MW-MEW),应用该评价方法和MW-MEW系统对兴路煤矿C9回风联络巷冒顶的风险程度进行了评价,与AHP-物元可拓模型评价结果作对比。结果表明:该评价方法的评价结果符合实际工况,并优于AHP-物元可拓模型。In order to reduce the risk of coal mine production,timely predict and control the risk of roadway roof fall,twelve evaluation indexes such as the thickness of stable rock strata,geological conditions and cross-section shape of roadway were selected.The risk evaluation index system of roadway roof fall was constructed,and the risk degree standard of roadway roof fall was proposed.The risk evaluation model of roadway roof fall was established by using the combination weight matter-element extension theory of analytic hierarchy process(AHP)and entropy weight(EW).The risk degree of roadway roof fall was determined according to the principle of maximum membership degree,and the risk assessment system of roadway roof fall(MW-MEW)was developed based on JavaWeb.The evaluation method and MW-MEW system were applied to evaluate the risk degree of roof fall in C9 return air connecting roadway of Xinglu Coal Mine,and the evaluation results were compared with those of AHP-matter element extension model.The results showed that the evaluation results of the evaluation method were in line with the actual engineering situation and were better than the AHP-matter element extension model.
