摘要 确定合适的开采方案是矿山企业必须考虑的重要问题,影响因素较多。针对山东某金矿矿体地质赋存特征及开采技术条件,在制定初步开采方案的基础上,采用改进的层次分析法和模糊数学理论优选开采方案。综合考虑影响开采方案选择的主要因素,建立了影响因素层次结构模型,基于改进的层次分析法即三标度法计算出开采方案各评价指标的权重,采用线性函数法和二元比较排序法实现决策指标的标准化及确定隶属度矩阵,进而构建了模糊数学综合评价模型;最后针对缓倾斜厚大矿体,利用模糊数学理论,得出待选开采方案的综合优越度分别为69.5%、67.6%和65.4%,从而确定上向分层胶结充填采矿法为最优开采方案。 Determination of appropriate mining scheme and consideration of affecting factors is crucial for mining enterprises.Based on the preliminary mining scheme,an improved analytic hierarchy process and fuzzy mathematics theory are used to optimize the mining scheme according to geographical characteristics and mining technical conditions of the gold mine in Shandong province.A hierarchical structure model of influencing factors is established considering the main factors affecting the selection of mining schemes.Based on the improved analytic hierarchy process,that is,the three-scale method,the weight of each evaluation index of the mining scheme is calculated.The linear function method and the binary comparison ranking method are used to realize the standardization of decision-making indicators and determine the membership matrix,and then the fuzzy mathematics comprehensive evaluation model is constructed.Finally,the comprehensive superiority of the mining schemes to be selected is 69.5%,67.6%and 65.4%,respectively according to the fuzzy mathematics theory.Therefore,the optimal mining scheme for gently inclined thick and large ore bodies is determined to be the upward slicing cemented filling mining method.
