摘　　要：基于赵固二矿的地质资料分析了矿井突水的成因;通过多种底板突水评价方法(突水系数法和"下三带"理论)综合分析了赵固二矿承压水上开采底板突水的危险性;根据赵固二矿的具体地质条件,提出了超前探测、疏水降压、地质体注浆改造等防治水技术措施,确保了工作面的安全回采。The reason for the water bursting was analysed based on the geological data. By using a variety of floor water inrush evaluation method（ the water-inrush coefficient method,the theory of ＂lower three zones＂ ）, floor water inrush risk above high pressure water was estimated. In addition,according to the specific geological conditions of Zhaogu No. 2 Coal Mine, some water control technologies were proposed, such as advanced detection,water discharge and depressurizing, and geological body grouting reconstruction. What have been done above ensured safe mining of working face.
