摘　　要：针对当前采空区塌陷安全评价结果准确性不高的问题.提出将变权理论和模糊模式识别理论同时运用于采空区塌陷安全评价中,建立采空区塌陷安全评价模型.通过事故树分析,找出引发采空区塌陷事故的最小割集、最小径集和各底事件的结构重要度,建立了3层次采空区危险评价指标体系.应用层次分析法确定指标权重,用变权对指标权重进行改进,糊模式识别理论确定其相对隶属度,构建了基于变权和权广义距离之和最小的采空区风险评价模型,应用该模型对某石膏矿采空区塌陷危险性进行评价.研究结果表明:该模型能很好的对采空区塌陷危险性进行评价,对采空区塌陷风险预测具有一定的参考价值.In order to improve the accuracy of safety assessment of goaf collapse,the variable weight theory and fuzzy recognition theory should be used in safety assessment of goaf collapse at the same time.Thus safety assessment model for goaf was established.Minimal cut sets,minimal path sets and the structural importance of each basic events were calculated by qualitative analysis to the fault tree.Three hierarchies assessment index system of the goaf risk was established,and their weight was determined by the analytic hierarchy process and adjusted by the variable weight theory.Relative membership degree of each factor was ascertained.Thus safety assessment model on variable weight theory and fuzzy recognition was constructed and was applied to a certain gypsum mine.The application results show that this model has good maneuverability and has certain reference value for the forecast of goaf collapse risk.
