摘　　要：桑树坪矿南回风大巷通尺490~512 m段巷道受B1背斜的影响,围岩破碎,顶板及帮部淋水量最大达到15 m^(3)/h,巷道变形严重,严重威胁南回风大巷的正常使用。通过注浆加固,该段巷道的淋水量减小到0.2 m^(3)/h,巷道几乎趋于稳定,说明注浆加固巷道围岩破碎带和封堵导水裂隙具有明显的效果,为巷道穿过破碎带区域的防治水指明了方向。The south return airway of Sangshuping Coal Mine is affected by the B1 anticline in the 490-512 m section of the roadway,resulting in the fragmentation of the surrounding rock and a maximum amount of water spray of 15 m^(3)/h on the roof and sides.The deformation of the roadway is severe,posing a serious threat to the normal use of the south return airway.Through grouting reinforcement,the amount of water spray into the roadway in this section was reduced to 0.2 m^(3)/h,and the roadway was almost stable,indicating that grouting reinforcement of the surrounding rock fracture zone of the roadway and sealing of the water-conducting fracture had obvious effects,pointing out the direction for the prevention and control of water in the roadway through the fracture zone area.
