摘　　要：根据冶坪煤矿开采技术条件,结合1308面回风巷原支护形式下的变形监测结果,采取锚索注浆方案对1308面回风巷进行加固。现场监测数据表明,采取锚索注浆方式加固的巷道段,其围岩控制效果明显。Based on the mining technical conditions of Yeping Colliery and combined with the deformation monitoring results under the original support form of return airway in 1308 working face,an anchor cable grouting scheme has been adopted to reinforce the return airway of 1308 working face,which proves obvious effect of controlling surrounding rock.
