In order to solve the problem of surrounding rock control of large-section roadway in fault fracture zone, combined with the surrounding rock geological conditions of Changping Mine 4320 air return roadway, the surrounding rock fracture mechanism of fault fracture zone roadway was analyzed, and advanced grouting reinforcement + anchor was proposed, cable support + I-beam reinforcement of the surrounding rock control program. The test showed that the advanced grouting reinforcement could improve the mechanical properties of the surrounding rock and improve the stiffness and strength of the surrounding rock. The active and passive support of the bolt and cable reinforcement support and the I-beam reinforcement could effectively control the harmful deformation of the roadway.
