Coal permeability models are derived normally under three common assumptions: (1) uniaxial strain; (2) invariant total stress; and (3) local equilibrium. Experimental measurements are normally conducted under constant effective stress or free swelling conditions. The inconsistency between model assumptions and the experimental conditions determines that these coal permeability models may not be appropriate...
When natural gas is extracted from coal seams, complex interactions of stress and sorptive chemistry have a strong influence on the properties of coal. These include influences on gas sorption and flow, coal deformation, porosity change and permeability modification. In this study, we define this chain of reactions as “coupled processes” implying that one physical process affects the initiation and...
