摘　　要：对影响深井采场凿岩硐室稳定性的因素进行了全面分析,并将影响因素分为4类。运用模糊数学中的综合评判法建立了硐室稳定性的评价模型,该模型包含二级模糊综合评判,共考虑了18个影响因子。此外,还建立了相关因子的隶属函数。以铜陵冬瓜山深井开采为实例,对采矿方法试验采场凿岩硐室的稳定性进行了评价,其结果与现场实际情况相吻合。The influencing factors relating to chamber stability of deep mining stope were fully analyzed, and the factors were divided into 4 types. The evaluation model was set up by comprehensive judgement method which belongs to fuzzy mathematics. The model consists of two - class fuzzy judgement and 18 influencing factors. Besides, the membership functions of related factors were derived. As an example, the drilling chamber stability of deep mining stope was evaluated, where mining method are testing in Tongling Dongguashan deposit. The evaluating result is in agreement with the actual situation.
