基于组合权重物元可拓模型的巷道冒顶风险评价
Risk assessment of roadway roof fall based on combined weight matter-element extension model
摘要
Abstract
In order to reduce the risk of coal mine production,timely predict and control the risk of roadway roof fall,twelve evalu-ation 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 con-necting 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.关键词
