摘　　要：针对晋北煤业3021巷道掘进超前段顶板破碎严重的问题,探索了注浆锚索主动式支护方案的可行性。工程实践有效控制了裂隙发育带、破碎带区域,围岩整体性和稳定性的提高增强了抵抗变形的能力,巷道围岩变形量及变形速率均在合理范围内,为后续生产提供了保障。In response to the serious problem of roof fragmentation in the early section of the 3021 roadway excavation in Jinbei Coal Industry Co.,Ltd.,the feasibility of an active support scheme using grouting anchor cables was explored.The engineering practice effectively controlled the crack development zone and fracture zone area,and the improvement of the overall integrity and stability of the surrounding rock enhanced its ability to resist deformation.The deformation amount and deformation rate of the roadway surrounding rock were within a reasonable range,providing a guarantee for subsequent production.
