The study provides experimental evidence of scientific ideas that are important for developing the phenomenological basis of the theory of phase transformations in the 'coal - methane' system accompanying the formation of gas-dynamic processes in coal beds when their initial stress-strain state and temperature background are disturbed during mining. Residual gas content of coal was determined versus the time after its recovery from coal beds and the weighted mean particle size; the effect of the pore structure of natural coals on the gas-dynamic activity of coal beds was estimated. It was shown that the major part of volatile compounds (mostly methane) is dissolved in the bulk of carbon layers.
