摘　　要：结合甘肃某矿的实际情况,建立了矸石井下分选与就地充填技术适用性评价层次分析模型,构建了综合模糊判断矩阵并计算各因素的权重,设立了分选+充填技术20种组合方式,结合专家评价法得到隶属度向量构造模糊关系矩阵,采用平均法求解隶属度,根据最大隶属度原则,得到分选与充填技术最优组合。多层次模糊数学综合评价表明,动筛跳汰分选+膏体充填开采技术为最优方案。Combined with the actual situation of amine in Gansu province, the analytic hierarchy model of applicability evaluation of underground gangue separation and in-situ filling technology is established.The comprehensive fuzzy judgment matrix is constructed and the weight of each factor is calculated.Twenty combinations of separation and filling technology are established. Combined with expert evaluation method, the membership vector is obtained to construct the fuzzy relationship matrix, and the average method is used to solve the membership. According to the principle of maximum membership,the optimal combination of separation and filling technology is obtained. The comprehensive evaluation of multi-level fuzzy mathematics shows that the moving screen jig separation + paste filling mining technology is the optimal scheme.
