摘　　要：为解决XV1101巷采动影响下围岩变形大的问题,采用现场观测+钻孔窥视的方式进行围岩变形特征分析,得出两帮煤体破坏深度为6 m,底板岩层变形呈现为凸凹分布;设计巷道两帮采用浅孔+深孔注浆加固,底板采用注浆锚杆加固,并在注浆加固补强方案实施后进行围岩变形监测分析。结果表明:补强方案实施后,围岩变形量小,保障了巷道围岩的稳定。In order to solve the problem of large deformation of surrounding rock under the influence of mining in the XV1101 roadway, the deformation characteristics of surrounding rock are analyzed by means of on-site observation + borehole peeping, it is concluded that the failure depth of the two sides of coal is 6 m, the deformation of floor rock layer is convexity and concave distribution, the two sides of the designed roadway are reinforced by shallow hole +deep hole grouting, the floor is reinforced by grouting anchor, and the surrounding rock deformation is monitored and analyzed after the implementation of the grouting reinforcement scheme. The results show that after the implementation of the reinforcement scheme, the deformation of surrounding rock is small, which ensures the stability of roadway surrounding rock.
