摘  要:针对干河矿三采区辅助运输巷围岩变形显著现象,基于对其变形机理及控制技术的分析,提出采用锚注支护技术强化围岩变形控制。通过中空注浆锚杆对围岩注浆改性,加强围岩力学性能,提高围岩承载能力,优化支护效果。现场应用结果表明:该技术的应用可有效控制围岩变形,监测的巷道变形量数据在可控范围内,保障了辅助运输巷在服务期间的通畅与顶板安全。Based on the analysis of deformation mechanism and control technology,the bolt grouting support technology is proposed to strengthen the surrounding rock control effect in auxiliary haulage roadway in No.3 Mining Area of Ganhe Colliery,by strengthening the mechanical properties of surrounding rock,improving the bearing capacity of surrounding rock and optimizing the supporting effect,which can effectively control the surrounding rock deformation within the controllable range and ensure the smoothness and roof safety of the auxiliary haulage roadway during the service period.
