Abstract: The excavation of the roadway sequence is the key factor to influence the stability of the surrounding rock，and three levels of local roadway model has been established by using the numerical simulation software.On two-level quasi roadway excavation is completed，through the quasi third level roadways is not boring and the mechanical characteristics of the surrounding rock under different excavation sequence analysis，which provide reference for reasonable excavation to the developing entry，in order to minimize the impact of roadway excavation on the surrounding rock.The numerical simulation result shows that with different excavation sequence，the stress distribution and safety coefficient of the surrounding rock have obvious difference，and the excavation of interval two routes at the same time have the minimum influence on the surrounding rock.
