| 摘 要： | 以平顶山十三矿己四采区底板灰岩的突水危险性评价为例，将熵权法(EW)和模糊层次分析法（FAHP）耦合在一起，确定了突水影响因素的权重，并建立了突水危险性评价模型。结果显示:十三矿己四采区二1煤底板标高-150~-350 m区域，不受底板灰岩水的影响，属于安全区；标高-350~-700 m 且不受断层影响的区域属于较安全区；标高-700 m以下及标高-350~-700 m且受断层影响的区域属于突水危险区。在前期突水资料少和数据量有限的条件下，EW-FAHP法能够较为客观地确定突水影响因素权重。

| Abstract: | In order to evaluate the risk of water inrush from Ji4 mining area floor limestone in Pingdingshan No.13 coal mine, the entropy weight method and fuzzy analytical hierarchy process (FAHP) are coupled to determine the weights of the factors affecting water inrush and establish a vulnerability index evaluation model. The results show that II1 coal seam floor of Ji4 mining area in the Pingdingshan No.13 coal mine elevation ranging from -150 to -350 m area, is not affected by the floor limestone water, belonging to the security zone; the area belongs to a relatively safe area which is not affected by the fault of the region in the elevation of ranging from -350 to -700 m; the area belongs to water inrush danger zone which is in the elevation of -700 m and below or influenced by faults in the elevation of ranging from -350 to -700 m. Under the condition of limited data on affecting water inrush factors, EW-FAHP can used to determine the weight of factors affecting water inrush. |
