摘　　要：介绍了段王煤矿根据090502工作面因采高与仰采角度大,在施采过程中,极易发生工作面煤壁片帮的实际情况,在分析工作面顶底板岩性,对锚杆性能测试的基础上,采用玻璃钢锚杆加固煤壁,防治片帮的技术。As the angle large of coal seam and mining height large in 090502 face of Wangzhuang Coal Mine, the accidents of coal wall spalling always happened in the roadway construction. Based on the analysis of roof lithology and anchor performance test, the rein-forcement coal wall technology by FRP Bolt for preventing spalling was used achieved remarkable results.
