Nuclear Magnetic Resonance Study on Microstructure and Permeability of Coals of Different Ranks
The microscopic pore development of most coal seams in China leads to different permeability of coal seams and different gas drainage efficiency. Representative three coal rank coal samples were selected for saturation-centrifugation observation. The microscopic pore characteristics of coal samples...
