Abstract: The urgency of the discussed issue: Studying of gas content of coal layers has century history, but also a number of fundamental issues about the reasons of existence of methane in layers, despite their not zero permeability in the direction to a day surface and gas pressure remains now. Opportunity deepening of this knowledge by the present time is provided with development of fundamental knowledge of properties and conditions of multicomponent geomaterials and achievements of electronics. Set of results of this development the uglemetanovykh of geomaterials and their empirical similarity in the form of the tests of coals which are artificially sated with methane allows to improve actively methods and means of studying directly. The main aim of the study: To develop a method of measurements thermodynamic properties gas-bearing and the gazonasyshchen of coals. The methods used in the study: Analysis and synthesis of scientific and technical information, justification and choice of the directions of researches, development of a method and equipment, carrying out laboratory and natural experiments. The results: The assessment of processes of gas–exhaustion of coals indicating transition of a condition of methane in coal after removal of tension from single-phase system to two–phase with sorption interaction of coal and methane on interfaces of phases is executed. It is shown that by means of modern technical and methodical means this conclusion can be quantitatively established even in such difficult part of measurements as thermodynamics of process of interaction of coal and gas.
