摘　　要：正中煤业2号煤层导水裂隙带高度不详,为确定2号煤层导水裂隙带高度,采用仰斜钻孔导高观测仪观测导水裂隙带高度。通过对不同钻孔深度下注水流量进行统计分析可知,2_上号煤层开采完毕形成的导水裂隙带高度为28.19 m,2_上、2_下号煤层都开采完毕形成的上覆岩层导水裂隙带高度为47.63 m。研究成果及方法对于其他矿井导水裂隙带高度实测具有一定的指导意义。The height of the water flowing fracture zone in No.2 Coal Seam of Zhengzhong Coal Industry Co.,Ltd.is unknown.In order to determine the height of the water flowing fracture zone in No.2 Coal Seam,the height of the water flowing fracture zone was measured with an upward inclined borehole height indicator.Through statistical analysis of the water injection flow rate a different drilling depths,it can be concluded that the height of the water flowing fracture zone formed after the completion o mining in No.2_(up)coal seam was 28.19 m,and the height of the overlying rock water flowing fracture zone formed after the completion of mining in both the No.2_(up)and No.2_(down)coal seams was 47.63 m.The research results and methods have certain guiding significance for the actual measurement of water flowing fracture zones in other mines.
