摘　　要：根据平里店矿区采空区的工程地质条件,选择四种残留矿柱回采的采矿方法进行综合评判。选取了技术经济和残矿回采安全2个方面的9个主要影响因素建立综合评判的指标体系,运用层次分析法确定了各层次间的判断矩阵并得到了各因素的权重向量。运用模糊决策理论建立了残矿回采方案优选的数学模型,根据最大隶属度原则,选定了最优方案。实践表明,全充填矿柱回收与空区处理一体化方案具有安全高效的特点,值得推广应用。Based on geological condition of the goaf in Pinglidian mine,four kinds of residual pillars recovery mining method are chosen for comprehensive evaluation.Choosing the nine main influencing factors with respect to technical economy and the residual ore extraction safety,the index system of comprehensive evaluation is established.Using the analytic hierarchy process,the judgment matrix among the various levels and weight matrix of different influence factors are obtained.The mathematical model of scheme optimization is built based on fuzzy decision theory,and the optimal proposal is determined according to the maximum membership grade principle.Practice shows that the scheme of full fill pillar recovery integrated with cavity processing has the characteristics of safety and efficiency,it is worth widespread application.
