Evolution of Coal Permeability during Gas Injection—From Initial to Ultimate Equilibrium
The evolution of coal permeability is vitally important for the effective extraction of coal seam gas. A broad variety of permeability models have been developed under the assumption of local equilibrium, i.e., that the fracture pressure is in equilibrium with the matrix pressure. These models have...
