Multi-scale x-ray computed tomography analysis of coal microstructure and permeability changes as a function of effective stress

Gas permeability (k) and porosity (f) are the most important parameters in CBM/ECBM and CCS in deep unmineable coal seams. k and f depend on the coal microstructure, and k and f significantly change with varying effective stress. However, how the coal microstructure is related to such permeability a...
