Abstract	In Gao Ping Chang Ping mine 4305 working face the cross-section area of tired car transportation lane is large, the stress environment is complex, its reasonable supporting parameters and the supporting form are worth deeply further analysis. Based on the results of in-situ stress measurement and rock loose circle, in conjunction with the situation of the roadway, proposes bolt and cable support approach to control the deformation of surrounding rock. Using existing support experiences proposes Programs. In order to find reasonable supporting parameters using finite difference flac2d numerical simulation software to research. Through comparatively analyzing simulation results of the roof and floor support programs, determines a reasonable program. Rock mass strength improves, displacements of two sides and roof of the tunnel significantly reduce. Project improves good effect.
