摘　　要：分析了张双楼矿9#煤层开采的充水含水层的富水性和导水性,利用突水系数法评价了9#煤层底板的突水危险性,根据评价结果和采区水文地质资料论证了疏降四灰水安全开采9#煤层的可行性,通过疏水降压工程的实施解放了受水害威胁的煤层。The water abundance and hydraulic conductivity of aquifer in No.9 coal seam of Zhangshuanglou Mine were analyzed,and the risk of water inrush from coal floor was evaluated by the aid of water inrush coefficients.According to the evaluation and the hydraulic information of mining area,the feasibility was demonstrated for the safe mining of No.9 coal seam after discharging the fourth limestone water.It is proved that the water discharge effectively avoids water inrush,achieving safe production.
