摘　　要：根据矿井水文地质条件,计算新义煤矿一水平工作面底板岩层采动导水裂隙带深度,对计算出的突水系数绘制成等值线图进行带压开采可行性分区,并根据存在的问题提出针对性的防治水措施,为矿井防治水工作提供参考依据和建议。According to the hydrogeologic conditions of Xinyi Coal Mine,the depth of hydraulic conductivity fracture zone was calculated,which was caused by the coal mining at No.1 level in the floor rock seam,and then,the water inrush coefficient was subareaed for the coal mining under pressure.The water prevention and control countermeasures were put forward against the existing problems.Some important recommendations were provided for water prevention and control.
