摘　　要：充填体是矿山充填开采的关键采场结构,其稳定性评判对矿山生产安全具有重要意义。针对目前充填体稳定性评价方法存在的模糊性和随机性的特点,提出了充填体稳定性综合评价方法。采用序关系分析法(G1法)和云化物元模型构建了充填体稳定性综合评价模型,以大冶铁矿某充填体为工程背景,采用G1法确定指标权重,利用MATLAB计算单指标的云关联度及综合评价向量,由最大隶属度原则确定大冶铁矿充填体的稳定性等级。研究结果表明:采用充填体稳定性评价方法评价的充填体稳定性等级与实际情况相符,可为深部金属矿山充填体稳定性评价提供新思路及新方法。Filling body is the key stope structure of mine filling mining,and its stability evaluation is of great significance to mine production safety.In view of the fuzziness and randomness of the current evaluation methods of filling body stability,a comprehensive evaluation method of filling body stability was proposed.The comprehensive evaluation model of filling body stability was constructed by using the order relation analysis method(G1method)and the cloud matter-element model.Taking a filling body in Daye Iron Mine as the engineering background,the G1method was used to determine the indexes'weights,and the cloud correlation degree and comprehensive evaluation vector of each single index were calculated by MATLAB.The stability grade of filling body in Daye Iron Mine was determined by the principle of maximum membership degree.The results show that the stability grade of filling body evaluated by the stability evaluation method of filling body is consistent with the actual situation,which can provide new ideas and new methods for the stability evaluation of filling body in deep metal mines.
