摘　　要：为了从定性和定量2个方面同时对巷道顶板冒顶隐患进行评价,通过理论分析,确定了影响巷道冒顶的5个关键因素,并利用AHP层次分析法得到了5个影响因素的影响权重,借助于物元定性方法和关联函数定量办法建立了基于可拓理论的新的巷道冒顶隐患可拓评价模型,将顶板冒顶隐患分为Ⅰ级、Ⅱ级、Ⅲ级和Ⅳ级共4个级别。并利用该新建可拓评价模型对长城矿1203运输巷进行了巷道冒顶隐患可拓评价,评价结果显示该巷道4处冒顶隐患为Ⅱ级,6处冒顶隐患为Ⅲ级。同时利用深基点位移计对顶板岩层位移进行了监测,监测结果显示冒顶隐患为Ⅱ级的顶板的最大位移为52 mm,冒顶隐患为Ⅲ级的顶板的最大位移为230 mm。In order to evaluate the roadway roof fall hazards from qualitative and quantitative two aspects, through the theoretical analy- sis, the author identifies five key influencing factors of roadway roof fall, and got the affection weight of five factors by using the analytic hierarchy process （AHP） . A new roadway roof fall hazard extension evaluation model is established based on the extension theory by the matter - element quantitative and dependent function qualitative method, which divided roadway roof fall hazards into levels Ⅰ , Ⅱ , Ⅲ and Ⅳ four levels. Besides, extension evaluation of the Great Wall 1203 transport roadway roof fall hazards has been done with the new extension evaluation model. Evaluation result shows that 4 evaluation places belong to level Ⅱ and 6 places belong to level Ⅲ. At the same time, the deep basis points displacement monitoring results show that the maximal displacement of the roof fall hazard for level Ⅱ is 52 mm and the maximal displacement for level Ⅲ is 230 mm
