Abstract: Based on the influence of the mining disturbance of the working face in the West Wing of a certain 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 the coal and rock mass in situ test results, using UDEC numerical simulation software simulation analysis of the hydraulic fracturing and grouting of roadway surrounding rock deformation and the influence of stress distribution, and industrial test in the field of 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. The research results provide an important basis for the design of roadway support under similar conditions.
