During the mining process of the No. 2 coal seam 1203 working face in the Yushupo Mine in Shanxi, the surrounding rock was seriously damaged due to the dynamic pressure of the adjacent working face. The main damage form was the roof collapse and the roadway sag collapse destruction and roadway bottom drum, etc., through numerical simulation research and analysis, the cause of instability of 1203 transportation and surrounding rock was severe mining dynamics, and it was divided according to the situation of 1203 transportation and the groove was affected by mining, and the surrounding rock of the mining area combined with the dynamic pressure were used for rework and reinforcement design. After the application, the surrounding rock displacement observation experiment was designed. The results showed that the 1203 transport groove was subjected to dynamic pressure by the adjacent working face. The influence range was 50 m in front and 70 m in the rear. The deformation of surrounding rock after rework and reinforcement was effectively controlled.
