摘　　要：在分析矿井地质及水文地质条件的基础上,采用脆弱性指数法对灵北煤矿2下煤层底板突水进行评价,运用AHP确定底板突水各主控因素的权重,建立煤层底板突水脆弱性模型,将研究区分为相对安全区、较安全区、过渡区、较脆弱区、脆弱区五个区。相对于传统突水系数法,脆弱性指数法评价更能全面分析研究各区域不同的脆弱性,有针对性地制定防治水对策措施与建议,对煤矿安全生产更具有指导意义。Based on coalmine geological and hydrogeological condition analysis,carried out the Lingbei coalmine coal seam 2L floor water bursting hazard analysis through the ＂vulnerability index method＂.Using AHP determined weights of main floor water bursting controlling factors,established coal floor water bursting vulnerability model,have divided the study area into 5 regions of relatively safe,rather safe,transition,rather vulnerable and vulnerable.In respect to traditional water bursting coefficient method,using this method to assess can analyze and study vulnerability of each region more comprehensively,pertinently set down water controlling countermeasures and suggestions thus have guiding significance in coalmine production safety moreover.
