基于 AHP －TOPSIS 评判模型的采矿方法优选--以小河金矿急倾斜薄矿体为例

摘要

针对安康紫金股份有限责任公司小河金矿急倾斜薄矿体复杂的开采技术条件，首先采用层次分析法确定经济、技术、安全三方面各评判指标的综合权重，再结合逼近理想解的排序法的基本原理，构建AHP－TOPSIS综合评判指标体系模型，计算出4种采矿方案基于评判指标的综合优越度[1]。结果表明，4种拟选采矿方案的综合优越度分别为42．2％，70．2％，34．0％和64．0％，即第II种方案（盘区无间柱连续留矿回采嗣后废石充填采矿法）最优。%In view of the complex mining technical conditions of the steeply inclined thin ore body of Xiaohe Gold Ore of Ankang Zijin Holding Ltd, firstly, establish the comprehensive weight of the economy, technology, security judging indexes, and then, the AHP-TOP-SIS comprehensive evaluation model was structured with the basic theory of technique for order preference by similarity to ideal solution, fi-nally, the superior degrees of mining method based on the comprehensive evaluation index were calculated[1] .The results show that the synthetic superior degrees of the optional mining methods are 42.2%, 70.2%, 34.0%and 64.0%, and the second method is the optimal.
