摘　　要：为解决运用数值分析方法获得最优采场结构参数中权重确定的难点,提出了一种基于组合赋权的逼近理想解的排序法(TOPSIS)综合评判方法。综合考虑影响采场结构参数中经济、技术、安全三大类因素,运用层次分析原理建立采场结构参数的评判体系,采用熵权法和层次分析法确定采场结构参数中各指标的组合权重,计算出各采场结构参数方案基于评判指标的综合优越度,实现采场结构参数的优选。最后,以湖南某矿山的采场结构参数选择为实例,建立了9种备选方案,得出5种安全可行方案的优越度分别为:方案2,40.8%;方案3,70.2%;方案5,26.8%;方案6,52.9%;方案8,4.7%,从而确定方案3最优。To solve the problem o f the difficulty using numerical analysis method to obtain the optimal stope structure parameters of the weight,we propose a technique for order preference by similarity to ideal solution（TOPSIS）based on combination of empowerment comprehensive evaluation method.Considering influence of stope structure parameters of the three categories of factors,such as economy,technology and safety.We establish the evaluation system of a stope structure parameters by the principle of analytic hierarchy process,determine combination and weights of each indicator using the entropy weight method and analytic hierarchy process（AHP）,and calculate the superior degrees of schemes based on the comprehensive evaluation index,finally,realizing,optimization of stope structure parameters.Taking the example of a mine in Hunan Province,nine schemes,fitting an orthogonal model,were tested,five of the nine schemes were assessed by empowerment combination TOPSIS evaluation model.The synthetic superior degrees of schemes are 40.8%,70.2%,26.8%,52.9% and 4.7% for the second,third,fifth,sixth and eighth ones,respectively,and the third scheme becomes the best.
