Ordovician water is located in common aquifers in deep mining, and underground water disaster caused by it has been one of the important reasons threatening the safe production. This paper explored the harmfulness of the Ordovician water on the basis of analyzing the hydrogeological conditions of mines combining with the specific engineering practice. And this paper put forward the corresponding prevention and treatment experience and technical measures combining with practical experience for better ensuring safe underground production in mines.%奥灰水作为深部开采中常见的含水层,由其引发的井下水害一直是威胁生产作业安全的重要原因之一.结合具体工程实际,在分析矿井水文条件的基础上,探究奥灰水的危害性,并结合实践经验提出相应的防治经验和技术措施,为更好地保障井下生产作业安全性提供帮助.
