摘　　要：金属矿地下采空区治理一直是矿山开采需要克服的难题之一。为探讨采空区稳定性评价,从系统工程的角度出发,应用模糊数学的基本原理构建某矿采空区稳定性二级模糊评价模型,采用四逻辑分区法确定隶属度函数,基于层次分析法建立权重分配矩阵,从而得出该矿采空区危险性评价结果。研究结果基本反映了目前该矿采空区的实际情况,为该矿空区治理提供参考。The treatment of metal mined underground goaf has always been one of the problems that mining needs to overcome.To discuss the evaluation of the stability of the goaf,from the perspective of system engineering,this paper applies the basic principle of fuzzy mathematics to construct a two-level fuzzy evaluation model for the stability evaluation of a goaf.The four logical partition function method is used to determine the membership function,and the weight distribution matrix is established based on the analytic hierarchy process.And the results of the risk assessment of the mining goaf are obtained.The results showed that the geological structure,high span ratio,rock mass structure,maximum exposed area are very important to the stability of the goaf.Factors such as the adjacent goaf,the inclination of the ore body,and the disturbance of the mining have certain influence on the stability of the goaf,but it is not the main factor.The research results basically reflect the actual situation of the mine goaf at present,and provide a reference for the mine goaf governance.
