Accurately understanding of the strata behaviors law and stability characteristics of the mining roadway is the basics of effective surrounding rock control, and the structural characteristics of the surrounding rock is the decisive factor for large deformation of that in mining roadways. In this paper, the surrounding rock structure characteristics of mining roadway in different conditions were discussed and mechanical model was established accordingly. And the deformation characteristics of the material were simulated by the combined model of deformation elements, and the theory of the surrounding rock deformation in the mining roadway with time was obtained.
