In order to solve the problem of large deformation roadway support in the deep shaft of Jiulong Mine, the roadway at the bottom of the downhill slope of the -850m track of Jiulong Mine was taken as the research object, the engineering geological characteristics of the area was systematically researched, and the reasons for large deformation of the roadway periphery under the condition of adopting the U36-type steel bracket support was analyzed. On the basis of comparing the bearing capacity of U36 steel support and φ194×8mm steel pipe concrete support, a support scheme with steel pipe concrete support technology as the core was proposed. The feasibility of the support scheme was preliminarily calibrated using FLAC3D numerical simulation and analysis method. The simulation results showed that the maximum deformation of the roof plate was reduced to 80mm, and the maximum deformation of the two gangs was reduced to 165mm, and the actual engineering application showed that the steel pipe concrete support technology could effectively maintain the long-term stability of the roadway.
