基于层次分析与模糊综合评判的回采方案优选

Optimization of stoping scheme based on comprehensive AHP and fuzzy evaluation

应用层次分析法与模糊数学原理,建立了某钨矿矿区回采方案的综合评判模型,科学合理地选出了该矿最优回采方案.在优选过程中,综合考虑影响回采方案的各项影响因素,利用层次分析法确定各评价指标的权重,并根据模糊数学原理对备选回采方案进行综合评判,得出各方案的优越度.实例计算结果得出2种方案综合优越度分别为0.791 0和0.748 1,因而确定方案1优于方案2.研究实例结果表明,该综合评判法可以对受多个定量和定性指标影响的决策进行有效的综合权衡分析,可为方案优选提供科学的指导.

The Analytic Hierarchy Process（AHP） and fuzzy mathematics principle are applied to establish a comprehensive evaluation model of mining methods of a tungsten mining area so as to select the optimal mining methods scientifically and reasonably. In the process of optimization, the superiority of the programs can be drawn by considering the various factors influencing the mining methods comprehensively,using the AHP to determine the weights of evaluation indexes and applying Fuzzy Mathematics Principle to make a comprehensive evaluation of the alternative stoping program. The result of examples calculation shows that comprehensive superiority is 0.791 0,0.748 1, hence program one is better than program two, which shows that this comprehensive method can make integrated tradeoff analysis of the decision that is affected by a number of quantitative and qualitative indicators effectively and provide scientific guidance for the optimization of method.
