煤矿断层采区承压水防治技术研究

Study on Prevention and Control Technology of Confined Water in Fault Mining Area of Coal Mine

为做好断层采区的水害防治工作,基于晋能控股煤业集团某矿3#煤层水文地质概况,介绍了顶板砂岩水控制技术,分析了底板高压灰岩水带压开采技术,提出了带压开采的相关技术路线,总结了部分水文地质保障及管理措施,并研究了突水灾害实时监测预警系统,介绍了其主要网络体系及关键功能模块,研究获得的这些承压水防治技术,可为该区域下组煤的安全顺利开采提供部分技术支持。

In order to do a good job in the prevention and control of water disasters in fault mining areas,based on the hydrogeological situation of 3#coal seam in a mine of Jinneng Holding Coal Industry Group,this paper introduces the water control technology of roof sandstone,analyzes the mining technology of floor high-pressure limestone water under pressure,puts forward the relevant technical route of mining under pressure,summarizes some hydrogeological guarantee and management measures,and studies the real-time monitoring and early warning system of water inrush disaster.The main network system and key functional modules are introduced.The prevention and control technologies of confined water obtained from the research can provide some technical support for the safe and smooth mining of lower group coal in this area.
