摘要
在综采工作面应用上下巷及瓦斯预抽巷深孔煤层注水结合工作面切眼浅孔注水,形成"网格式"煤层注水,大大提高了注水效果,解决了松软破碎煤层回采期间煤墙片帮严重,煤尘大和瓦斯涌出异常的现象,筑起了"人造煤墙",很好的改善了工作面生产条件,为高效安全生产打下良好基础。
In mining working face, taking the method of infusing into coal seam with deep holes combine with the shallow holes infusion into open-off cut of upward and downward roadway and gas drainage roadway. This will format the ＇Grid＇ coal seam injection and improve the effect of water injection greatly. At the same time, it will solve the problem of the rib spalling at coal wall of the soft and broken coal seam dur- ing the stoping procession, coal dust is heavy and abnormal phenomenon of methane gas emission. Build an ＇artificial coal wall＇ which improv- ing the working face production conditions and make a good foundation for the efficient and safe production.
