摘　　要：针对煤层底板水害对煤炭资源安全开采的威胁,在详细分析井田地质及水文地质等资料的基础上,确定并分析影响底板突水危险性的各主控因素,运用AHP方法确定各主控因素对底板突水的影响权重,利用GIS的空间叠加功能对各主控因素叠加分析,得出煤层底板突水危险性分区图,并与传统的突水系数法评价结果对比,验证脆弱性指数的正确性,为煤矿的安全生产提供保障。Aiming at the coal floor water inrush threat to coal mining safety, based on the detailed analysis of the coal geology and hydro-geology data, the main factors affecting the coal floor water inrush risk were confirmed and analyzed,using AHP method to confirm the weights of each factor, and fusing the main factors using the spatial and overlay function of GIS. Finally, getting the zoning map of coal floor water inrush risk, compared with the traditional water-inrush coefficient method zoning result, the comparison shows that the vulnerability index method results are more correct and can provide protection for the safety of coal mining.
