| Abstract: | In order to ensure the stability of the surrounding rock of the roadway，the deformation and failure characteristics of the surrounding rock of the roadway were theoretically analyzed，and the distribution of the deformation rate of the surrounding rock of the roadway after excavation and the relationship between the roadway plastic zone and the original rock stress were obtained；the numerical simulation analyzed different supporting conditions，the vertical stress distribution of the lower roadway and the vertical stress distribution of the roadway roof under different lagging support schemes had obtained the optimal support scheme.Finally，on-site measurement and analysis were carried out to verify the feasibility of the supporting scheme. |
