In order to effectively solve the problem that the roof caving of the 14218 working face transportation, the specific geological conditions and deformation characteristics of the roadway and the stability control technology of the roof were analyzed. The support technology of long anchor rod + long and short anchor cable was proposed, combined with the roadway. The specific circumstances of the support program were specifically designed and monitored for mine pressure. The results showed that after the multi-layer support technology of layered roof was implemented, the maximum subsidence of the roof was 70 mm, and the maximum displacement of the two sides was 160 mm, which effectively controlled the appearance of roadway roofing and ensured the stability of surrounding rock.
