Numerical simulation research on dynamical variation of permeability of coal around roadway based on gas-solid coupling model for gassy coal
Due to the change of initial stress state caused by roadway excavation, the permeability of the coal body may be changed during the excavation process. In this paper, according to the different stress states, the coal around the roadway was divided into the seepage open zone, seepage orientation zon...
