Numerical study of changes in coal permeability in a mining workface
At the front of a working coalface, the stress state can differ significantly across different zones. This seriously affects the permeability of the coal seam. In this study, we adopt a discrete element method to study the coal permeability under different stress states. The results indicate that...
