In order to effectively solve the problem that the 3408 transport roadway with possible roof caving and large deformation of surrounding rock under the original support, according to the analysis of deformation condition of transportation roadway to the reinforcing support mechanism, the reinforcement can be strengthened by using the long bolt, the specific parameters of the reinforcement support scheme were specifically designed, and the mine pressure monitoring was carried out on the roadway after reinforcement and support. The results showed that after the implementation of the reinforcement support scheme, the maximum displacement of the top and bottom plates was 42 mm and 68 mm, respectively, which ensured the stability of the roadway surrounding rock.
