摘　　要：针对当前传统安全评价方法存在的问题,结合煤矿冲击特性随着生产的动态变化特点,建立模糊综合评价模型,利用正态隶属度函数进行指标的隶属度计算,将冲击特性指标体系分为属性权重和等级权重,利用最小信息熵原理把二者综合为组合权重,并评价指标矩阵模糊运算,得到煤矿冲击危险等级。结合乌东煤矿南采区+500B1+2和B3+6工作面现场地质条件和开采现状,采用该评价模型分析得出该区域回采工作面冲击危险等级为三级,即中等冲击危险等级,并采用地震波CT技术进行对比分析,结果表明该模型在实践中得到较好的验证,为类似条件下冲击危险等级判定提供了参考。A fuzzy comprehensive evaluation model whose membership function is calculated by thenormal membership function is established in this thesis according to inadequacy in the traditional safetyevaluation and the fact that the state of the whole mining system is changed with the working face advance.The degree of rock-burst can be gained when the weight of the factors are divided into attributive weight andthe rank weight followed by the fuzzy matrix operation. This fuzzy comprehensive evaluation model issuccessfully used in the d-500Bl＋2 and B3＋6 working face of WuDong coal with the result that the degree ofthe rock burst is Ill , which is also be verified by ultrasonic CT technology. This good proved method inpractice provides a preference to the similar conditions.
