Abstract:
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.
