沿空下山掘进巷井下探放水技术实践

Practical Application of Underground Water Detection and Release Technology for Roadway Driving along Next Goaf

五阳矿75采区南部在两采空工作面间煤柱内布置沿空总回风巷,为防止采空区积水影响掘进安全,调整探放水施工设计,针对性地对巷道探放水方式进行改进,采用长短探结合的循环近探近放技术,确保了巷道在沿空掘进时不受相邻采空区积水的威胁,取得了良好的实践效果,丰富了探放水的方法和手段。

To prevent the goaf water from influencing driving safety at 75 mining area of Wuyang Colliery,the paper presents the adjustment of the water detection and release construction design with micro-pressure long and short detection combined with the cyclic proximity detection and release technology to avoid the threat of the adjacent old goaf water damage to the roadway when driving along the goaf,which has a good application effect and enriches the methods and means of detecting and releasing water.
