摘要: 为准确观测多煤层重复采动导水裂隙带发育高度,分析了现有的两带高度观测常用方法,由此提出了多煤层重复采动条件下导水裂隙带高度的观测方法,并将其应用于布尔台煤矿22105工作面及42106工作面导水裂隙带高度的观测,得出多煤层重复采动条件下42106工作面导水裂隙带高度为158.52m,裂采比为24.02。而由经验公式计算得出,多煤层重复采动条件下42106工作面导水裂隙带高度为131.44m,裂采比为19.92,这与实际观测结果基本吻合,验证了实测结果的准确性。

Abstract: Abstract: Hazard of water inrush and shaft accidents including overlying aquifer and goaf water,which threaten safe production of coal mine seriously.Therefore,the accurate observation of the height of water flowing fractured zone will provide theoretical basis for the preventionand control of water disaster in coal mines.The paper introduces the methods of observing water flowing fracture zone hight and make feasibility analysis to its.Based on this,the method of observing water flowing fracture zone hight of compound goaf is introduced and applied it to 22105 and 42106 working face of some coal mine.Good observation results are obtained.
