[en] The porosity system of coal consists of two key parts, fractures (termed cleats) and much smaller pores in the matrix. Any change of the cleat network likely modifies the permeability of the material. For instance, the aperture of the fractures may be affected by the evolution of the gas content adsorbed in the matrix. Indeed, coal swells (or shrinks) due to the gas sorption (or desorption).
