根据层次分析法(AHP)和理想点法(TOPSIS),建立采矿方法优化排序的数学模型,该数学模型采用德尔菲法(专家意见法)确定采矿方法优化排序的决策指标,如倾角、厚度和顶板稳固性等;将待选方案指标转换为判断矩阵,通过层次分析法确定判断矩阵中各指标权重,然后用理想点法进行优化排序,得到加权标准化的决策矩阵,从而计算出各方案的相对贴近度。以三山岛金矿采矿方法的优化方案为例,3种采矿方法的相对逼近度为0.1467,0.5168,0.9706,以此确定第3种方法最优,进而验证模型的可行性,为矿山采矿方法的优化提供有效参考。
According to Analytic Hierarchy Process (AHP) and Ideal Point Method (TOPSIS), a mathematical model for optimizing the ranking of mining methods is established. The mathematical model uses Delphi method (expert opinion method) to determine the decision indexes for optimizing the mining method, such as inclination, thickness and The stability of the roof and so on. The index of the alternatives is converted into a judgment matrix, and the weight of each index in the judgment matrix is determined through the analytic hierarchy process. Then the optimal point method is used to optimize the ranking, and the weighted normalized decision matrix is obtained, Closeness. Taking the optimization scheme of the mining method of Sanshandao Gold Mine as an example, the relative approximation degree of the three mining methods is 0.1467, 0.5168 and 0.9706, so as to determine the optimality of the third method and verify the feasibility of the model for the mining method Optimization provides a valid reference.
