Abstract: Aiming at the problem of support difficulties.In this paper, the maximum depth of damage of the interlayer rock mass is 1.21 m by theoretical calculation.The anchorage of the shovel roof is proved.The damage characteristics of the surrounding rock of the shed roof and the end effect of the guiding section are analyzed.The influence of the anchor belt mesh with the grouting anchor cable is proposed, and a reasonable support scheme is designed.The feasibility of the scheme is verified by numerical simulation.Finally, the on-site industrial test is carried out.The field test data show that the sub-regional support scheme can effectively restrain the surrounding rock deformation, improve the stress state and structural characteristics of the surrounding rock, and give full play to the self-supporting ability of the surrounding rock.The scheme has a significant support effect in the process of guiding the raft under the close seam of the coal seam.
