Investigation of the process of gas saturation and degassing of the Donets Basin coals’ samples of various degrees of coalification is performed. Saturation of fossil coal samples is carried out on a universal installation of high gas pressure that allows carrying out the gas saturation in four chambers. Argon, nitrogen, and carbon dioxide are used as the model gases. The particle size of coal are of 2–5 mm. Saturation of the gases of coal samples is carried out at room temperature for 3–14 days at a pressure of 2.000 bar. As shown, the gas output of coal samples can be described by two mechanisms, namely, filtration and diffusion. A typical time of the diffusion mechanism of gas output is different by several times compared to the filtration.
