Abstract: Song Xinzhuang Coal Mine 110303 working face return airway is affected by 110301 working face mining, the roadway shows large deformation characteristics and cannot meet the normal production needs. Therefore, during the mining of the working face of the wing 110302 in the mining area, the roof of the transportation roadway is constructed intensively drilling and cutting top relief technology, so as to optimize the post-mining lateral stress distribution of the 110304 return airway. Combined with the geological conditions of the working face, through theoretical analysis and Flac3D numerical simulation, key technical parameters such as roof cut-ting height, angle and hole spacing were determined, and the stress evolution law of the surrounding rock of the roadway before and after roof cutting was studied. The amount of displacement in the roadway was signif-icantly reduced. Industrial tests have shown that after the top cut and pressure relief, the development of fis-sures in the roof and surrounding rocks of 110304 return airway was reduced, the relative displacement of the two helpers was 249 mm and the relative displacement of the top and bottom plates was 237 mm. This tech-nology can provide some technical reference for subsequent mining in Song Xinzhuang coal mine.
