Based on the broken roof, serious rib spalling and mining pressure of thick coal seam nearby goaf, in view of the problem that the roof of the large-section roadway was crushed, the roadway of the 23105 belt roadway in Xiegou Mine was deformed, with serious rib spalling adjacent to the goaf, through numerical simulation and theoretical analysis, the cause of the severe pressure of the mine pressure was analyzed. By optimizing the design of the 23105 belt roadway support, the pressure of the large section roadway in the adjacent goaf was solved severely, providing a reference value for the large-section roadway support.
