    • Abstract
  • Using Mohr-Coulomb plasticity constitutive model,Isotropic-Fluid-Flow constitutive model and Fluid-Mechanical Interaction seepage calculation mode,the FLAC3D numerical model of seepage calculation of solid-fluid coupling was established,and the "excavation-support-re-excavation" simulation process was used.Through the simulation analysis on the deformation and failure mechanism of the track roadway at the depth of 600 m of 38th panel in Shizuishan No.1 coal mine,the key parts of deformation and failure in deep roadway were concluded,which provided a new theoretical basis for deep tunnel support.
