摘要: 国投新集一矿210606工作面掘进期间受上方210806工作面采空区积水的威胁,通过分析研究,打破常规探放水模式,提出在-550m轨道石门施工俯角钻孔超前探放210806面采空区积水的方案。实践证明:利用俯角钻孔负压状态下超前探放老空区积水是完全可行的,具有操作安全简单、可控性好、放水流量稳定、维护运行费用低、疏放水工期超前等优点,为类似条件下超前疏放老空区积水提供了宝贵的经验。

Abstract: Abstract: SDIC Xinji Mine 210606 face by over 210806 face goaf water threat during the210606 face excavation, through the analysis, break the routine drilling escape mode is presented in -550m Shimen of track ahead of exploration drilling construction depression discharge 210806 face gob water solution. Practice has proved that: the use of depression ahead of exploration drilling put under negative pressure water Old Mining Area is entirely feasible, safe and easy to operate, good controllability, turn on the water flow stability, maintaining low operating costs, water drainage ahead of schedule, etc., under similar conditions ahead for the old Mining Area Drainage of water provides a valuable experience.

Key words: Keywords: negative, depression angle, drilling escape, Old Mining Area water
