Abstract The deep shaft coal seam roadway of Tai’an Mine was taken as the research object, the stress and stress concentration coefficient of the roadway were analyzed theoretically. By creating a model and using FLAC3D software, the change law of the disturbance between the roadway groups with the spacing was derived, and finally the response characteristics of the drill and blast method to the disturbance of the first-excavated roadway were simulated and analyzed with FLAC3D software, which provided a reference for the future mining of similar roadways.
