According to the analysis of the geological conditions of the auxiliary transportation along the N1302 working face in Gucheng Mine, it was determined that the rock mass strength of the roadway, the shape, size, geostress and support time of the roadway were important factors affecting the deformation and failure of the surrounding rock of the roadway. Anchor rod + mesh + anchor cable + reinforced ladder beam combined support method was adopted to support the roadway. Practice proved that the support effect was good, it could effectively maintain the stability of the roadway and ensure the safe and orderly production.
