The hydrogeological conditions of karst coal deposits in North China were very complex, and Hanxing mining area was one of the most typical representative mining areas. For a long time, due to high-intensity mining in Hanxing mining area, the recoverable reserves of the mine were seriously insufficient. With the continuous increase of mining depth, the threat of Ordovician limestone water outburst was increasing day by day. The traditional water prevention and control technology and experience could no longer meet the requirements of safe mining. This paper selected No.182602 Face of Wutongzhuang Mine as the research object, analyzed the abnormal hydrogeological conditions of the working face, and expounded the prevention and control countermeasures of high confined water disaster, in order to lay a solid foundation for the breakthrough innovation of water disaster prevention and control in North China Coal Mine.
