For the method for grouting reinforcement of the fault fracture zone of a coal mining working face, a treatment idea of combining regional treatment with local treatment is adopted. The regional treatment is implemented ahead of the coal mining working face by a certain distance and is divided into static treatment and dynamic treatment, and advanced grouting reinforcement treatment is performed; local treatment is implemented in the working face; and the combination of regional treatment and local treatment can better achieve step-by-step progressive treatment of the fault fracture zone, and can achieve comprehensive and dynamic fault treatment free of blind corners.
