Abstract Based on the serious deformation of belt roadway in Xinzhuang Mine, the deformation features and reason were analyzed, with the reason of poor surrounding rock, high clay minerals, underground water, poor support and high ground stress, combined with repair maintenance of the roadway, reserved deformation + anchor mesh spray + secondary anchor injection support coupling support was put forward, the coupling support stabilized the deformation of the roadway, providing reference for support under similar conditions.
