Flow Theory of Gas in Coal Seams

  • Chapter
  • First Online:
Coal Mechanics

Abstract

The form of gas migration in coal seams is either diffusion or seepage, and is closely related to the fracture scale and pore size distribution. However, the characteristic of inhomogeneous pore structure exists in natural coal seams, and has been simplified by some researchers on the basis of the primary and secondary effects of seepage and diffusion in coal seams.
