Abstract：Based on the influence of the mining disturbance of the working face in the west wing of Yuwu Mine,the deformation and failure of the working face is affected seriously,and the integrated control technology of the hydraulic fracturing roof and grouting reinforcement is put forward.According to the in-situ stress and coal-rock mass in situ test results,UDEC numerical simulation is carried out to analyze the influence of hydraulic fracturing and grouting on surrounding rock deformation and stress distribution.Also,industrial test is conducted in the roadway.The research results show that: the comprehensive control technology of hydraulic fracturing and grouting reinforcement can effectively reduce the stress and deformation of surrounding rock,and shorten the time of roadway stability.
