Abstract： In view of the loose and broken surrounding rock of deep roadway under mining disturbance, large deformation and difficult to maintain roadway stability by conventional support means, No. 8 mining track downhill of Yunjialing Mine was taken as the engineering background, the failure characteristics of surrounding rock of deep roadway under mining disturbance was analyzed, and the deep and shallow hole grouting reinforcement scheme was put forward based on improving the mechanical properties of surrounding rock and enhancing the anchorage of surrounding rock. Field monitoring showed that deep and shallow hole grouting reinforcement could solve the problems of grouting leakage, not easy to pressure and insufficient penetration caused by unbalanced mechanical properties of surrounding rock. After cementation, the structure of rock mass was complete and continuous, and the overall stability of surrounding rock was improved. The total deformation of surrounding rock under mining disturbance decreased and reached the stable stage faster, and the effective control of surrounding rock was realized.
