摘　　要：以某矿+750 m水平运输大巷围岩控制为工程背景,对引起巷道围岩变形的原因、机理进行分析,针对围岩变形特点,提出以锚索补强+注浆为主的巷道修整技术方案,并详细对修整技术方案以及应用效果进行阐述。现场应用后,围岩变形量得到明显控制,围岩变形不会给巷道后续运输、通风造成不利影响,取得了显著的修整效果。Taking the surrounding rock control of 750 m horizontal transport roadway as the engineering background,this paper analyzes the causes and mechanisms of surrounding rock deformation, and puts forward the technical scheme of roadway dressing based on anchor cable reinforcement grouting according to the characteristics of surrounding rock deformation, and expounds the technical scheme and application effect of dressing in detail. After the field application, the deformation of surrounding rock can be obviously controlled, and the deformation of surrounding rock will not cause adverse effects on the subsequent transportation and ventilation of roadway, and obtain remarkable repair effect.
