Abstract Rongtai coal mine west wing rail transportation roadway deformation damage was taken as a research object, through the field survey and theoretical analysis, the main reason leading to a full section of the roadway deformation damage depended on complex stress, the roadway was located in the stratum of poor lithology loose ring range, the original support was not reasonable enough, combined with the actual Rongtai Mine, rework using a "square section steel pipe restraint concrete arch + anchor mesh cable support" rework support scheme, roadway stability was effectively controlled, with good repair support effect.
