为了确定矿山合理的采矿方法,综合考虑经济、技术和安全3个方面对采矿方法的影响,利用层次分析法原理建立采矿方法综合评价模型,采用层次分析法和熵值法确定评价指标组合权重,再结合逼近理想解的排序法(TOPSIS)理论确定各方案的优越度,确定最优采矿方法。以赵家湾铜矿采矿方法选择为例,确定各备选方案的综合优越度分别为50.3%、50.7%、60.7%,从而确定方案Ⅲ最优。研究结果表明:该方法运用于采矿方法的选择中是科学的、合理的。
In order to determine the reasonable mine mining method, considering the economic, technical and safety aspects of the impact of mining methods, the use of analytic hierarchy process to establish a comprehensive evaluation method of mining methods, the use of analytic hierarchy process and entropy to determine the weight of the evaluation index combination, Combining the TOPSIS theory with the ideal solution, the superiority of each scheme is determined and the optimal mining method is determined. Taking Zhaojiawan mining method selection as an example, the overall superiority of each alternative solution is determined to be 50.3%, 50.7% and 60.7%, respectively, so as to determine the optimal solution III. The results show that this method is scientific and reasonable for the selection of mining methods.
