Abstract: Mining-induced roadway in large dip angle coal seam affected by the factors such as goaf and coal pillars, the failure laws of surrounding rock and the characteristics of mining pressure are complex and vary greatly, making support and maintenance difficult. In response to this issue, taking the 3123 return airway of the large dip angle coal seam in Lyushuidong Coal Mine as the engineering background, a comprehensive research approach using theoretical analysis, numerical analysis, and field experiments was employed to analyze the failure patterns of the surrounding rock in large dip angle coal seam roadway. The study revealed the stress characteristics of the surrounding rock at different locations and the deformation and failure characteristics of the roadway under these stresses. The results indicate that under the effect of large dip angle and mining, the maximum principal stress and the principal stress difference around the roadway are relatively large, resulting in the plastic zone of the roadway showing characteristics such as non-uniformity and the maximum failure depth deviation, moreover, the location of the roadway determines the distribution range and shape of the plastic zone of the surrounding rock; as the roadway gradually moves away from the upper working face, the impact of mining decreases, when the roadway is located 12 m or more below the upper goaf along the coal seam, the maximum principal stress and the principal stress difference remain stable at 15-20 MPa and 5-10 MPa respectively, under this stress environment, the size and shape of the plastic zone of the surrounding rock around the roadway do not change significantly. Based on key influencing factors such as the deformation and failure laws of mining roadways in large dip angle coal seams, the geometric characteristics of roadway sections, and the structural characteristics of coal and rock, the non-uniform active-passive support parameters of anchor rods (cables) were designed, and an industrial test was conducted in the 3123 return airway, and the monitoring of the deep displacement of the roadway roof was carried out, during the roadway excavation process, the total deformation of the roadway roof was controlled within 100 mm, and the main deformation was concentrated in the soft coal layer of the roadway roof, and the control effect of the surrounding rock of the roadway was good.
