Abstract In order to solve the problems of caving and hydraulic support death in the fully-mechanized coal face, the 11103 working face of Ciyaogou coal Mine was taken as the engineering background, and the roof control technology of the working face was studied by analyzing the special geological conditions and the mechanism of roof deformation and failure. Results showed that by means of grouting reinforcement and reinforced support management and the initial supporting force and checking technical measures to control roof, and other auxiliary measures to improve the physical and mechanical properties of surrounding rock, improved the overall carrying capacity of surrounding rock, the hydraulic support working resistance monitoring data showed that the technical measures could effectively solve the problem of working face roof control, at the same time provided a reference for the same engineering geological conditions of coal mine enterprises and reference value.
