针对深部矿井巷道受承压水威胁在巷道服务期间易产生滞后突水问题。采用理论分析方法，研究了巷道滞后突水防治技术。分析结果表明：随着时间的延续，巷道围岩有效隔水层在矿压及水压长期作用下，围岩破坏范围逐渐扩大，裂隙进一步扩展，有效隔水层受到破坏，裂隙与高承压水连通，形成突水通道；分析了突水时间效应及防突水措施机理，提出了通过优化支护参数达到增强防突潜能的目的。基于悬吊理论和 Ansys 软件，对巷道支护参数及安装载荷进行了优化。结果表明：断层破碎带附近巷道顶底板最大位移量为132 mm，两帮移近量最大为123 mm，顶板离层量为8～15 mm，巷道围岩得到了有效控制，在服务期间，没有发生淋水等现象。该成果对预防巷道滞后突水有一定指导意义。

In view of the deep mine roadway threatened by confined water are prone to water inrush during service period, using theoretical analysis method, the prevention and control technology of lagging water-bursting was investigated. The results show that the damaged zone increasing and crack extending, the damaged effective water-resisting layer and the connected fissure with high water, form water inrush channel due to mine pressure and water pressure with a continuation of time. Optimizing support parameters was put forward to enhance outburst-prevention potential according to analyzing the time effect of water inrush and prevention measures mechanism. Based on suspension theory and Ansys software, the supporting parameters and installation load were optimized. The results show that the maximal roof-to-floor convergence was 132mm, the maximal two sides convergence was 123mm, and the roof bed separation value was about 8~15mm near fault zone. The surrounding rock had been effectively controlled, and the phenomenon such as rain dripping did not happen during the service period. The study results have some guiding significance for effectively preventing lag water-bursting of roadway.
