我国华北岩溶类煤矿床水文地质条件非常复杂,而邯邢矿区是最具典型代表性的矿区之一。长期以来,邯邢矿区由于高强度开采,矿井可采储量严重不足,随着采深的不断增加,奥灰水突水威胁日趋加大,传统的防治水技术和经验已不能满足安全开采的要求。本文以梧桐庄矿182602工作面为研究对象,对工作面出现的异常水文地质条件进行分析,并阐述了高承压水害的防治对策,以期为华北煤矿水害防治突破性创新奠定坚实基础。
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.
