摘　　要：在对平顶山矿区回采巷道围岩松动圈数据统计基础上,应用粗糙集理论对围岩松动圈影响因素的重要性进行研究,得到了各影响因素的权重;通过实例验证了回采巷道围岩松动圈影响因素权重的准确性.分析表明:在影响回采巷道围岩松动圈的4个主要因素中,围岩节理发育程度对其影响最大,其次是巷道跨度和巷道埋深,最后是围岩强度.On the basis of the statistical data of broken rock zone around mining roadways in Pingdingshan mining area, the importance of influence factors of broken rock zone around mining roadway is studied by using rough set theory, and the weights of the influence factors are obtained. Finally, the veracity of the result is verified by practical application. The analytical results show that among the four main influence factors of the broken rock zone around mining roadway, the joint propagation degree has the strongest effect on the broken rock zone, the second is the depth of roadway and the span of roadway, and the last is the surrounding rock strength.
