基于组合赋权TOPSIS的采矿方法优选

Mining method choice based on empowerment combination TOPSIS

针对传统采矿方法选择存在的弊端以及数值优选权重确定的难题,综合考虑影响采矿方法选择的技术、经济、安全等因素,利用层次分析法基本原理建立了采矿方法综合评价指标体系,采用层次分析法和熵权法对决策指标进行组合赋权,运用基于组合赋权的逼近理想解排序法对待选采矿方法进行综合评价,计算出各方案的综合优越度,实现采矿方法的优选。最后,以云南某矿为例,设计了3种备选采矿方法,得出待选方案的综合优越度依次为0.033 03、0.583 49、0.966 96,从而确定方案3环境再造中深孔落矿嗣后充填采矿法为最优。研究结果表明,基于组合赋权的TOPSIS法在采矿方法选择的评价中更合理、更可靠。

With all influencing factors, such as technology, economy, and safety considered, a comprehensive evaluation index system of mining was established by using the basic principle of ana- lytical hierarchy process（AHP） to solve the drawback of traditional mining method selection and the problem in determining the weight of numerical optimization. Optimization of mining method was achieved by applying AHP and entropy to empowerment combination, using the technique for order preference by similarity to ideal solution （TOPSIS） to assess the mining methods, and calculating the synthetic superior degrees of every mining method. Taking the example of a mine in Yunnan Province, the synthetic superior degrees of the three mining methods were 0. 033 03, 0. 583 49 and 0. 966 96, respectively, with the third method i. e. , environment regenerating medium-length hole blasting and subsequent filling mining method, being the best. The result shows that the method choice based on TOPSIS is more reasonable and reliable.
