Abstract Based on the large deformation damage of the Rongtai-760 west transportation roadway, the main reason for the apparent deformation damage of the lane is the high and complex ground stress in the location of the lane, with the poor lithology of the surrounding rocks, the low strength of the original support and the seriousness of the tectonic stress. Fully combined with the roadway where the geological stress conditions, "anchor net cable spraying + local grouting to strengthen" repair support strategy was designed, from the repair situation, the overall stability of the alley was controlled, with certain reference.
