摘要
Abstract
The minable seam is NO. 3 coal seams in Yi Qiao mine, there are more large faults and associated faults. When the roof is pouring water, sometimes the phenomenon of roadway roof caving occurred. In dealing with the roadway roof, before excavation, the use of the double liquid grouting reinforcement with cement and water glass is safe and reliable, feasible and economical and easy to operate. By adopting the embedded grouting pipe, spraying plugging, and grouting reinforcement, can successfully solve the problem of roadway roof.关键词
