Abstract: In view of the problems of roof and coal wall slabs encountered when the working face passes through the fault, the 14207 fully mechanized mining face of Majialiang Mine is taken as the background. By establishing the mechanical model of the elastic deep beam of the roof in the fault zone of the working face, the stress distribution law of the roof is analyzed, and the surrounding rock control technology of the rigid-flexible coupling with the rigid-flexible coupling is proposed. Flac3d is used to calculate and analyze the proposed control scheme, and combined with on-site monitoring data for comparison and determination. The research shows that the top plate breakage of the working face is mainly caused by the effective ultimate shear stress; the plastic zone range and the roof subsidence of the surrounding rock are obviously reduced in the simulation; the measured displacement of the roof is reduced from 38 cm to 7 cm, and the subsidence is reduced 81.6% small. The shallow and shallow zone rigid-flexible coupling grouting surrounding rock control technology can effectively solve the problem of roofing and chipping.
