摘    要:结合未确知测度理论和层次分析法构建1个采矿方法优选模型。模型综合考虑影响采矿方法选择的诸多不确定因素,并从中选取合适的评价指标。根据各指标分级标准构建单指标测度函数,进而计算出各指标的未确知测度,并由层次分析法确定指标权重向量。用置信度识别准则确定评价等级并测定优越度,最后得出优选结果。以湖南郴州瑶岗仙钨矿为例,得出3个待选方案的评价等级分别为Ⅲ,Ⅰ和Ⅱ,优越度分别为1.480 0,2.501 6和1.973 6,从而确定第2种方案为最优。

Abstract: Combined with the uncertainty measurement theory and analytic hierarchy process (AHP), a mining method optimization model was established. During this process, variable uncertainty factors which influenced mining method were taken into account, and some appropriate factors were selected as evaluation index. According to the classification standards of each index, a single index measure function was constructed, the uncertainty measurement of each index was calculated, and the weights of the influence factors matrix were established according to the AHP method. The evaluating grade was determined with credible degree recognition criterion, superior degrees were measured and finally the optimization results were obtained. Taking Yaogangxian Wolfram Mine for example, the results show that the three methods’ evaluation levels are Ⅲ, Ⅰ and Ⅱ, and superior degrees are 1.480 0, 2.501 6 and 1.973 6, indicating that the second method is the optimal.
