| Abstract: |
| Based on geological condition of the goaf in Pinglidian gold mine, four kinds of residual pillars recovery mining method are chosen for comprehensive evaluation. Choosing the nine main influencing factors from technical economy and the residual ore extraction safety, the index system of comprehensive evaluation is established. Using the analytic hierarchy process, the judgment matrix among the various levels and weight matrix of different influence factors are obtained. The mathematics model of scheme optimization is built based on fuzzy decision theory, and the optimal proposal is determined according to the maximum membership grade principle. Practice shows that the integration project of full fill pillar recovery and cavity processing has the characteristics of safety and efficiency, it is worth popularization and application. |
