Past studies have established the relationship of these parameters and patterns of change with increasing degree of disturbance coal. Determined pressure methane adsorbed in micropores impaired coal caused by a force field of molecular interaction of methane with the walls of the pores and gas molecules together. Patterns of change in varying degrees since methane filling. For the first time revealed the possibility of manifestation of the effect of "double release" in mining operations in coal high degree of disturbance. Modeling of methane desorption process from the zone of disturbance coal seam. The regularities of changes in the concentration of methane depending on the activation energy of conformational transitions in molecular structure of coal, its degree of metamorphism and depth of the reservoir. The features of these unconventional patterns and factors that control the process of methane desorption from the zone of disturbance coal seam. Scientific novelty consists in keeping the molecular-mechanical state of sorbed methane in coal microstructure in describing the process of methane desorption zone disturbance coal seam.
