摘　　要：奥灰是区域性强含水层之一,对开采太原组煤层威胁很大,通过对山东新驿煤矿首采区奥灰水文地质条件的分析,在对其突水影响因素综合分析的基础上,用有效隔水层突水系数法、多层叠加抗压强度比值系数法、安全隔水厚度比值系数法等三种方法从不同角度对突水危险性进行了划区评价,经相互对比验证,效果较为理想。Ordovician limestone is one of strong aquifers regionally and has larger threatening to mining of Taiyuan Formation coal seams. Through analysis of Ordovician limestone hydrogeological condition, based on comprehensive analysis of water bursting influencing factors, used three methods of effective confining bed water bursting coefficient method, multiple beds stacked compressive strength ratio coefficient method and safety water tight thickness ratio coefficient method to appraise water bursting hazard region by region, after mutual contrast verification, considered that the effect is rather perfect.
