A surface diffusion block coefficient and model about coal-adsorbed gas

80%−90% of coalbed methane(CBM)/coal mine gas is stored in adsorbed state, and the diffusion of adsorbed gas is dominated by surface diffusion, which plays a decisive role in the transportation of CBM. The paper adopts kinetic and thermodynamic methods, based on CHEN and YANG’s surface diffusion gas...
