Abstract
The results of the simultaneous control of the sorption of gaseous CO2 and the swelling of fossil coals from the Donets Basin under quasi-equilibrium conditions were analyzed. It was established that the isotherms of sorption and deformation obey the Langmuir formula in the region of sorbate pressures to 4.5MPa. A linear correlation between the Langmuir sorption and deformation coefficients was found for a group of coals with the high yield of volatile substances, and a swelling criterion was established. A nonlinear relationship between the swelling of coal and the amount of the sorbed substance was obtained.
