摘　　要：为了对煤层底板隐伏陷落柱突水进行危险性评价优化,在对主要影响因素分析的基础上,建立煤层底板岩溶陷落柱突水危险性评价体系。运用差离方法和优化组合层次分析法和主成分分析法所得的权重确定优化最佳权重,从而建立基于优化组合赋权法的煤层底板岩溶陷落柱突水危险性评价模型。最后以葛亭煤矿陷落柱为例进行工程验证,结果表明:含水层水压和隔水层厚度影响因素对煤层底板隐伏陷落柱突水影响最大,该模型能优化主观和客观评价的权重,减少了主观评价方法的人为影响和客观评价方法的过于依靠客观数据,能合理客观地反映影响因素之间的差异,实现对煤层底板岩溶陷落柱突水的危险性评价。In order to optimize the risk assessment of water inrush from coal floor collapse column, based on the analysis of main influencing factors, the risk assessment system of water inrush from coal floor karst collapse column is established. The optimum weight is determined by using the difference method and the optimum combination analytic hierarchy process（AHP） and the principal component analysis method. Finally, the collapse column of Geting Coal Mine was taken as an example for engineering verification, the results showed that the water pressure of aquifer and the thickness of water-resisting layer have the greatest influence on the water inrush of underground collapse column of coal seam. This model can optimize the weight of subjective and objective evaluation, reduce the artificial influence of subjective evaluation method and relying too much on objective data of the objective evaluation. It can reflect the differences among the influencing factors reasonably and objectively and realize the risk evaluation of water inrush from karst collapse column of coal seam floor.
