Abstract: In order to achieve efficient and safe equipment withdrawal in the ultra-high working face of Houcun Coal Mine of Qinhe Energy Group Co., Ltd., the 3503 working face withdrawal channel was taken as the research object. The pressure situation of the basic roof in the area was analyzed through theoretical analysis, numerical simulation, and underground actual measurement methods. The pressure step distance in this area has been determined to be 18.9 m. When the distance between the working face and the main retreat channel is 7 m, it is most affected. When the working face is about 2.4 m before the connection, the pressure disappears, and the basic roof of the tunnel will be about 5 m away from the center coal pillar of the retreat channel in the next pressure cycle. Based on the analysis of the pressure situation during the retraction process, an innovative support scheme using constant resistance anchor cables and steel belts for partition support and overall pressure bearing was proposed. Practical applications have shown that the new support technology can ensure the stability of the roadway roof during the retraction process of the support. The high height hydraulic support of the entire working face can complete retraction in 11.5 days, which is 33.2% more efficient than traditional retraction, It has achieved rapid and safe retraction of ultra-high equipment.
