Mining standards and engineering roadways, as passageways for mine transportation, ventilation, and pedestrians, play an important role in mine safety production. Through the methods of observation and theoretical analysis of the surrounding rock deformation of the roadway, the deformation law of the overburden roadway under the mining face under the influence of mining were studied, and corresponding control measures were proposed. The study found that the deformation of the roadway was divided into three stages, and it showed asymmetric deformation under the influence of mining. The top and bottom converged sharply, the maximum deformation was 300 ~ 400 mm, and the bottom mainly, followed by the two sides. Aiming at this, control measures such as pressure avoidance, reserving pressure relief grooves, and strengthening support were proposed, which provided a reference for the layout and excavation and maintenance of the roadway under the influence of mining.
