Abstract：In order to effectively control the deformation of surrounding rock in deep mining roadway, combined with the typical engineering geological conditions of a coal mine, the evolution laws of stress and deformation of roadway surrounding rock under the influence of mining is simulated, the surrounding rock reinforcement control technology for deep mining roadway is proposed, and industrial test is carried out. The research results show that the surface displacement of roadway is consistent with the corresponding stress variation trend with the advancing of working face, the size of protective coal pillar in the roadway is 105 m;the main roadway deformation can be effectively controlled by adopting the heavy U-shaped backfilling, bolt-cable cooperative bearing and delayed grouting.
