Water Prevention and Control Technology of Fully Mechanized Mining Face Passing through Fault in Tectonic Stress Area of Houcun Coal Mine

为解决综采工作面向斜轴部回采过断层期间水害防治难题,保证工作面安全回采,分析断层水害形成机理,基于DF14断层、导水裂隙带发育特征、规律及工作面受水害影响特征,形成“一重点、两阶段、六措施”防治水技术体系,工作面漏顶及淋水问题得到解决并顺利通过A5向斜轴部及DF14断层构造叠加区域,为该矿类似条件下其他工作面过断层防治水工作提供了工程经验及技术支撑。

In order to solve the difficult problem of water disaster prevention and control during fully mechanized mining face inclined shaft mining through fault,ensure safe mining of working face,analyze the formation mechanism of fault water disaster,based on the development characteristics and laws of the DF14 fault and water diversion fracture zone and the characteristics of working face affected by water disaster,the water prevention and control technical system of"one key point,two stages and six measures"is formed.The problem of roof leakage and water leaching in the working face has been solved and successfully passed through the A5 syncline axis and the structural superimposed area of the DF14 fault,which provides engineering experience and technical support for the water prevention and control work of other working faces passing through faults under similar conditions in the mine.
