Abstract: In response to the deformation problem of the track roadway under the influence of multiple mining activities in the close range coal seam of Xiashijie Coal Mine, the deformation and failure characteristics of the surrounding rock of the 950 track roadway were analyzed.The FLAC^3D numerical simulation method was used to study the failure law of the surrounding rock of the track roadway after excavation, and after mining in four working faces including 2302,2303,224 and 226.The displacement of the track roadway roof, the displacement of the two sides, the plastic zone, and the vertical stress changes in each excavation and mining stage were compared and analyzed.Based on the on-site situation, the “early strength dual component+micro nano single component” deep and shallow hole joint grouting control technology was proposed, and industrial experiments were conducted to further evaluate the grouting reinforcement effect by monitoring the anchor load and drilling stress changes.The research results indicate that as the number of repeated mining operations increases, the maximum deformation of the track roadway increases linearly.After grouting, the maximum reduction in anchor rod load is 10.9%,and the maximum increase in surrounding rock stress is 6.06%.Grouting reinforcement can effectively suppress the impact of multiple mining operations on the track roadway.
