In order to ensure the stability of the surrounding rock during the roadway along the 1103 transportation roadway, the structural characteristics of the roadway along the goaf were analyzed. The theoretical analysis and numerical simulation method were used to determine the parameters. The reinforcement support scheme during the roadway was specifically designed, and the mine pressure observation was carried out during the retained roadway. The results showeded that the maximum displacement of the top and bottom of the roadway was 449 mm, and the maximum displacement of the two sides 284 mm, which ensured the stability of the surrounding rock in the roadway.
