为满足缓倾斜薄矿体采矿方法科学优选要求,构建了基于AHP-VWT-TOPSIS的采矿方法多属性综合决策模型.采用VWT规避AHP法确定的常权权重向量可能出现的"状态失衡"问题,再结合TOPSIS逼近理想解排序法得到各方案优越度,选出最优采矿方法.以贵州某金矿为例,结合矿山开采实际,提出了 3种可行的采矿方案.从经济、技术和安全3个层面,选取了 13个评价指标,构建了采矿方法优选多属性综合决策矩阵,通过建立的综合决策模型计算得到3种方案的贴近度分别为0.2132,0.4913和0.5802,推荐采用方案三(液压支柱护顶壁式崩落法).优选结果符合工程实际,应用效果表明,该综合评判模型对采矿方案优选具有一定的工程应用价值.
Optimization of Mining Methods for Gently Inclined Thin Orebody Based on AHP-VWT-TOPSIS
A multi-attribute comprehensive decision model was constructed,which based on AHP-VWT-TOPSIS,to meet the requirements of scientific optimization of mining methods for gently inclined thin orebody.The variable weight theory(VWT)was used to avoid the"state imbalance"problem of the constant weight vector determined by the analytic hierarchy process(AHP)method,and then combined with technique for order preference by similarity to an ideal solution(TOPSIS)to obtain the superiority of each solution and select the optimal mining method.Taking a gold mine in Guizhou as an example,combined with the actual mining situation,three suitable mining schemes were proposed.From the three levels of economy,technology and safety,13 evaluation indexes were selected to construct a multi-attribute comprehensive decision matrix for mining method optimization.Through the established comprehensive decision making model,the comprehensive superior degrees of the three schemes are 0.2132,0.4913 and 0.5802,respectively,and it is decided to adopt the scheme 3,that is the hydraulic prop roof protection wall caving method.The optimization results are in line with the engineering reality,and the application effect shows that the comprehensive decision model has a certain engineering application value for optimization of mining methods.
