摘　　要：文章基于某工作面巷道的基本情况,设计了群锚支护方案,缩短锚杆长度和钻孔深度,并对优化后的巷道锚杆支护方案进行顶板离层监测、巷道收敛监测、锚杆轴力监测。监测结果显示,优化后的支护方案可满足该巷道的围岩使用要求,提高了巷道的支护能力。Based on the basic condition of a roadway in the working face,the group anchor support scheme is designed to shorten the length of the bolt and the depth of the borehole,and the roof separation monitoring,roadway convergence monitoring and bolt axial force monitoring are carried out for the optimized roadway bolt support scheme.The monitoring results show that the optimized support scheme can meet the surrounding rock use requirements of the roadway and improve the support capacity of the roadway.
