In order to effectively control the reasonable deformation of the track inclined shaft in the pre-design and the extension design of the coal industry, three kinds of surrounding rock control technologies were proposed based on the existing supporting problems and the stress characteristics of the surrounding rock of the roadway. In the original supporting design, repair and reinforcement schemes were adopted, and the surface displacement of the surrounding rock of the roadway and the change of the deep surrounding rock were continuously monitored. The results showed that the displacement of two sides and the deformation of roof and floor were only 131 mm and 451 mm respectively under the existing support mode after the implementation of the rehabilitation and reinforcement scheme, which met the requirements of safe use of the roadway.
