Damage‐induced permeability model of coal and its application to gas predrainage in combination of soft coal and hard coal
Abstract Coal permeability is a key parameter that affects the drainage of coal bed methane (CBM). Owing to the lower original permeability of coal seams in China, more attention was paid to the study of damage‐induced permeability laws. However, the theory of damage‐induced permeability still needs...
