不良地质条件下承压开采回采面底板水害防治探究

Study on Prevention and Control of Water Damage in Floor of Mining Face under Pressure Mining under Unfavorable Geological Conditions

底板承压水害作为威胁矿井生产安全的主要因素之一,实现对其的有效治理意义重大。以此为着手点,针对不良地质条件下承压开采回采面底板水害防治展开分析,结合具体工程实际,在分析底板突水危险性的基础上,对底板注浆加固技术应用做出探究,希望能够为其他矿井相似工程的开展提供借鉴与参考。

The floor confined water damage is one of the main factors threatening the safety of mine production. It is of great significance to achieve effective management of the damage. Taking this as a starting point, this paper analyzed the prevention and control of water damage in floor of mining face under pressure mining under unfavorable geological conditions. Combined with the actual engineering practice, based on the analysis of the risk of water inrush from the floor, the application of floor grouting reinforcement technology was explored, hoping to provide reference for the development of similar projects in other mines.
