摘 要:华北型煤田受奥灰水害威胁严重,水害已成为制约我国煤矿安全高效开采的重要隐患。为解决唐家会煤矿带压开采所受的底板奥灰水威胁,保障工作面的安全掘进和回采,以61304工作面Y6地质异常区为研究对象,采用地面定向水平钻对地质异常区域精准实施探查和注浆改造,查明了Y6异常区岩溶异常发育情况,注浆封堵了底板奥灰岩溶裂隙与导水通道,消除了治理区内回采6号煤层的突水威胁,取得了良好的治理效果,有效保障了矿井安全生产。North China coalfields are seriously threatened by ordovician limestone water hazards, and water hazards have become an important hidden danger restricting the safe and efficient mining of coal mines in my country.In order to solve the threat of ordovician limestone water from the floor of Tangjiahui Coal Mine under pressure, and to ensure the safe driving and mining of the working face.Taking the 61304 working face Y6 geological anomaly area as the research object, and the ground directional horizontal drilling was used to accurately exploration and grouting transform the geological anomaly area, the abnormal development of karst in Y6 abnormal area has been found out.The grouting has blocked the ordovician limestone karst fissure and water-conducting channel in the floor, eliminated the water inrush threat of the 6 # coal seam in the treatment area, achieved good control effect, and effectively guaranteed the safe production of the mine.
