摘要
为建立采矿方案综合评判指标体系,在综合层次分析法(AHP)、灰色关联分析法(GRA)和加权TOPSIS法基本原理的基础上,构建加权TOPSIS-灰色关联综合评判模型,对多种采矿方案进行综合评判优选。优选过程中,从经济、技术、安全3大类因素综合考虑影响采矿方法的评判指标,通过层次分析法获得各评判指标的权重向量,利用灰色关联系数改进加权TOPSIS法,建立加权TOPSIS-灰色关联综合评判模型,并运用TOPSIS法原理计算出各方案基于评判指标的综合优越度。以石人沟铁矿露天转地下采矿方案优选为例,得出4种拟选采矿方案的综合优越度分别为47.9%、62.5%、63.9%、59.9%,确定第3种采矿方案最优。经矿山实践验证了该评判模型的可行性和有效性。
In order to choose an appropriate mining method, a synthetic assessment index system was established. A comprehensive evaluation index system model based on the basic theory of the Analytic Hierarchy Process （AHP）, the Grey Relation Analysis （GRA） and the weighted TOPSIS was established to optimize the mining methods. During the process, the evaluation indexes in the mining method were comprehensively considered in view of economy, technology and security. The weight matrix of the evaluation indexes was established according to the AHP method, then, according to the weighted TOPSIS improved by the grey relational coefficient, a weighted TOPSIS-GRA comprehensive evaluation model was established, and the synthetic superior degree of the mining methods based on the influence factors was obtained by the TOPSIS methods. Taking the mining method optimization in the transition from the open pit to the underground mining in Shirengou Iron Mine as an example, the synthetic superior degrees of four kinds of optional mining methods are 47.9% ,62.5% ,63.9% and 59.9%, respectively. According to this analysis, the third mining method is the best. The feasibility and the effectiveness of the evaluation model are verified by the mine＇s production practice.
