摘　　要：为了优选出矿山更适宜的采矿方案,构建了一种基于变权重理论(Variable weight theory,VWT)和灰色关联法(Gray relational analysis,GRA)的综合评价指标体系,对3种候选方案进行综合评判。考虑到采用熵权法等方法确定的常权评价各候选方案时可能出现"状态失衡"的问题,依据变权重理论(Variable weight theory,VWT),根据各因素状态(即取值状况)的不同,适当调整其权重,以保证各因素的均衡性,进而利用GRA法计算出各方案的综合优越度,最终确定各采矿方案的优劣程度。结果表明:3种候选方案的综合优越度分别为51.1%、47.7%、49.0%,从而确定方案1为最优方案,符合工程实际情况,该综合评价指标体系对于矿山选择最佳开采方案具有一定的参考价值。In order to select out the most suitable mining scheme, a comprehensive evaluation indexs system based on variable weight theory （VWT） and gray relational analysis （GRA） is established so as to evaluate three candidate schemes. The fixed weights decided by the conventional methods such as entropy weight method may result in ＂ state out of balance＂ phenomenon, according to this situation, based on the variable weight theory, the weights are adjusted according to the the difference of the config- uration of each factor （ the value of each factor status） to ensure the balance of various factors. Combining with GRA, the comprehensive superior degree of three schemes is calculated to determine the best one. The results show that the superior degree of the are 51.1% ,47.7% ,49.0% respectively, so, the first scheme is the optimal one. The consequence is consistent with the engineering situation, and the results further prove that comprehensive evaluation indexs established in this paper has a reference value for selecting the mining method.
