Coalbed methane: A review
TL;DR: In this paper, it is shown that the micropores are where most methane adsorption occurs in coal seams, and the methane molecule may actually stretch, minutely, the pore and thus with de-gassing of the reservoir, could result in matrix shrinkage, allowing opening of the fracture (cleat) system in the coal and thus enhancing permeability.
