辛置煤矿10-428B工作面导水裂隙带发育高度研究

Research on Development Height of Water Conducting Fissure Zone in 10-428B Face of Xinzhi Coal Mine

为准确掌握10-428B工作面导水裂隙带的发育高度,根据工作面特征,采用基于压力拱效应的薄板理论进行导水裂隙带动态高度的分析,具体分析上覆岩层导水裂隙带的动态发育规律,计算得出导水裂隙带的发育高度为42.56m,进一步通过工作面钻孔窥视的方式得出导水裂隙带发育高度为48.68m,验证了理论分析的正确性,准确掌握了工作面上覆导水裂隙带的发育高度。

In order to accurately grasp the development height of the water-conducting fissure zone in the 10-428B working face,the dynamic height of the water-conducting fissure zone is analyzed using the thin plate theory based on the pressure arch effect according to the charac-teristics of the working face.According to the development law,the development height of the water conduction fracture zone was calculated to be 42.56m,and the development height of the water conduction fracture zone was 48.68m through borehole peeping through the working face,which verified the correctness of the theoretical analysis and accurately mastered the work The development height of the water-conducting fissure zone on the surface.
