Abstract: In order to effectively solve the difficulties encountered in the production of roof sinking, plate helping, roof climbing, pressure frame, and inverted frame during the over-empty lane of the large mining high working face, and ensure the safe passage through the empty lane area during the mining of the working face. In view of the problems of long length, large section and parallel layout of the working face of the 5314 large mining high face of Chengzhuang Mine, the control of surrounding rock in the air lane is studied by combining theoretical analysis with field industrial tests. The process of filling overpass lanes with high water materials is proposed and applied in the field. The results show that the use of high water materials to strengthen the support for the empty lane area can effectively control the harmful deformation of the surrounding rocks in the empty lane area, ensure the safe, efficient and rapid passage of the working face through the empty lane area, and compared with the Muduo and the single hydraulic support. High water materials filling support has significant economic benefits.
