深部矿压高承压奥灰水防治技术探究

Research on Prevention and Control Technology of Ordovician Limestone Water under Deep Mine Pressure and High Pressure

在矿井深部回采中,高承压奥灰水对生产安全构成严重威胁,实现对奥灰水的有效治理,对于矿井的长久发展意义重大。以此为着手点,结合具体工程实际,在分析常规超前探测技术和底板注浆加固技术不足的基础上,提出了区域超前治理技术,并对其实践应用做出分析和总结,希望能够为其他矿井深部回采中奥灰水的有效防治提供借鉴。

In deep mining,high-pressure Ordovician limestone water poses a serious threat to the safety of production.To achieve effective control of Ordovician limestone water is of great significance for the long-term development of the mine.Taking this as a starting point,combined with the actual project,on the basis of analyzing the shortcomings of advanced detection technology and floor grouting reinforcement technology,this paper put forward regional advanced control technology,and made analysis and summary of its practical application,hoping to provide reference for the effective prevention and control of Ordovician limestone water in deep mining of other mines.
