Surrounding rock control in roadways with weak roof and floor has long been regarded as a difficult issue in support design for coal mine mining roadways. The haulage roadway of the No.2618 Face in the No.2 coal seam of Zhangcun Mine was taken as the engineering background and research on grouting reinforcement technology was carried out with. Field investigation was conducted, which showed that roadway deformation was characterized by long duration, large deformation magnitude, and rib heave as the dominant form. The FLAC3D numerical simulation software was adopted to analyze the deformation mechanism, and it was found that poor self-stability capacity of the surrounding rock was regarded as the main cause of severe deformation. On this basis, grouting reinforcement technology was proposed. Prestressed grouting composite materials were added into ordinary cement slurry, by which the initial setting strength was improved and the shrinkage rate of the consolidated body was reduced. Combined with enhanced measures such as bolts and cables, roadway deformation of mudstone roofs and floors was effectively controlled.
