With the increase of mining depth, under high ground stress, surrounding rock deformation showed engineering soft rock characteristic. Bolting and grouting can effectively control the surrounding rock stability of soft rock roadway, on this basis, the bolt-grouting supporting mechanism and timing injection anchor were analyzed. Research showed that the shotcrete layer can timely seal roadway surrounding rock, prevent rock weathering weakening control, improve the surrounding rock stress state; effectively control the surrounding rock movement and deformation; tunneling after shotcrete, timely anchor-plate retaining, and anchor support when surrounding rock movement regional was stable, which ultimately implemented the stability of surrounding rock. Engineering practice showed that the anchor bolting roadway surrounding rock convergence rate decreased, realized the stability of surrounding rock.
