Coal resources are still dominant in national resources, and in the process of mining coal, the increasing depth of burial is a situation that must be faced at present, so the problem of roadway rock control is unavoidable. This paper comprehensively adopts the method of combining theoretical analysis and numerical simulation to design the support scheme for the transport roadway of 30101 working face in Yang gui coal industry, and analyzes it using FLAC3D numerical simulation software to verify the feasibility of the support design. It is concluded that after the support is carried out, the transportation tunnel can ensure that the deformation of surrounding rock can be controlled within a reasonable range, and the stability of the roadway is significantly improved, and the safe and rapid advance of the mining operation is ensured at the same time.
