中文摘要：

为解决盛大铁矿低效开采的难题，运用改进的AHP-TOPSIS综合评价指标体系模型，对5个采矿方案进行综合评判优选。从经济、技术、安全3方面综合考虑影响采矿方法的评判指标，通过改进的层次分析法客观地确定各评判指标的权重向量。结合逼近理想解的排序法原理，构建改进的AHP—TOPSIS综合评判指标体系模型，基于评判指标计算出5种采矿方案的综合优越度。结果表明，5种采矿方案优越度依次为29％、28％、21％、22％、20％，其中分段接力退采分段充填采矿法为最优。

英文摘要：

In order to solve the mining technical problem of low exploitation in Shengda iron ore, an improved AHP-TOPSIS comprehensive evaluation index system model was established to evaluate t＇ive kinds of mining methods. Considering the economy, teehnology and security, which impact the evaluation indexes of mining method, the weight matrix of＇ the evaluation indexes was established according to the improved AHP method, and then the improved AHP-TOPSIS comprehensive evaluation model was established with the basic theory of TOPSIS. The degrees of mining method based on the comprehensive evaluation index were calculated. The results show that the synthetic superior degrees of the optional mining rnethods are 29%, 28%, 21%, 22%, 20%, and the first method named piecewise relay retrograded mining filling method is the optimal.
