  • This study establishes an improved fully coupled gas migration model for CBM extraction. 
  • The permeability rebound and recovery times as well as rebound values are proposed to accurately quantify permeability evolution during CBM extraction.
  • The evolution of these three parameters under the influence of different factors are evaluated in detail, such as initial gas pressure, the diffusion coefficient, and the permeability. 
  • The permeability rebound and recovery times are found to increase along with initial gas pressure and the amount over time rises rapidly under high gas pressures.
