AHP FUZZY在残采工程方案优选中的应用

为探讨太白金矿回收原采场边部残余低品位矿体的方案，通过层次分析法（AHP）与模糊数学（FUZZY）理论，选取对残采工程影响较大的9个因素，建立优选模型。运用层次分析法确定了各评价指标的权重；采用模糊数学法分析计算各采矿方法的定性、定量指标，分别得到各评价指标的隶属度。最终计算出3种工程布置方案的综合优选度分别为68.1%、69.3%、58.1%，从而沿矿体走向双进路布置确定为最优开采方案。实践表明，采用该模型优选的工程布置方案具有一定的科学性、合理性，值得借鉴与推广。

Application of AHP Fuzzy in Optimization of Residual Mining Project

In order to discuss the scheme of recovering the remaining low grade ore bodies at the edge of the original stope in Taibai Gold Mine,through the analysis of AHP and FUZZY theory,9 factors that have a significant impact on the residual mining project were selected and optimized.The model uses the analytic hierarchy process to determine the weight of each evaluation index.The fuzzy mathematical method is used to analyze and calculate the qualitative and quantitative indicators of each mining method to obtain the membership degree of each evaluation index.Finally,the comprehensive preference of the three engineering layout schemes is calculated.They are 68.1%,69.3%,and 58.1% respectively.Therefore,the two path layout along the ore body is determined as the optimal mining plan.Practice has shown that the optimal engineering layout scheme using this model is scientific and reasonable,and it is worth learning and promoting.
