摘　　要：官地矿28416工作面副巷掘进过程中遇到围岩波动范围大等问题使日常顶板管理困难,通过采用高预应力锚杆锚索支护系统的巷道支护形式并分别对顶板位移顶板离层以及锚杆锚索受力进行日常监测。监测结果表明,高预应力锚杆锚索支护系统很好地控制了官地矿28416工作面副巷围岩稳定性,且解决了综放托厚夹层厚顶煤全煤巷道支护技术难题,提高了巷道掘进速度,降低了巷道支护综合成本。In tunneling process of assistant tunnel in 28416 working face of Guandi mine, surrounding rock fluctuat ion makes the daily roof management difficult. The roadway supporting form of high prestressed bolt and cable supporting system is used for daily monitoring of roof displacement and roof separation and bolt and cable force. The monitoring results show that the high prestressed bolt and cable support system effectively controls the stability of wal l in assistant tunnel of 28416 working face in Guandi coal mine and solves the technical problems of thick coal seam roadway with thick roof in fully mechanized top coal caving mining, improves the speed of roadway driving, reduces the comprehensive cost of roadway support.
