摘　　要：为解决松软破碎围岩巷道变形量大、支护困难等问题,以11203运输巷为研究对象,对巷道在锚网索喷支护条件下的围岩变形机理进行了分析,并提出了在原有支护技术上使用锚注、底板支护进行补强加固。通过锚注提高了松软破碎围岩的自身稳定性及抗变形能力,使得原支护用锚杆及锚索由端锚变为全锚,增强了围岩的支护强度。工程实践表明,11203运输巷采用补强加固技术方案效果显著,可实现对松软破碎围岩变形的有效控制。In order to solve the problems such as large deformation and difficult support of roadways with soft broken surrounding rock,the deformation mechanism of surrounding rock under anchor net and cable shotcrete support of roadway was analyzed with 11203 transport roadway as the research object,and it was proposed to use anchor injection and floor support for reinforcement of the original support.By anchoring,the stability and deformation resistance of soft broken surrounding rock were improved,and the original supporting bolts and cables were changed from end anchor to full anchor,and the supporting strength of surrounding rock was enhanced.The engineering practice showed that the reinforcement technology scheme of 11203 transport roadway had remarkable effect,which can effectively control the deformation of soft broken surrounding rock.
