    • Abstract
  • We carried out fuzzy comprehensive evaluation on the stability of goaf under the condition of Wuyun expressway. According to the actual geological and mining conditions of the mined out area and the construction of Wuyun expressway, 19 factors are selected to establish the two levels model of fuzzy comprehensive evaluation. We use the analytic hierarchy process （ＡＨＰ） ｔo determine the weight set of fuzzy evaluation factors, and use expert scoring method to evaluate the qualitative factors, and use Cauchy distribution function and linear function to evaluate quantitative factors, and obtain fuzzy evaluation matrix of all influence factors. Finally, according to the weight set and evaluation matrix of fuzzy, the comprehensive evaluation of goaf could be completed. The results show that the two-grade evaluation model can objectively and accurately reflect the stability of the goaf, which is a reliable and effective evaluation method.
