Abstrakt: Generalized data of paleotemperature conditions, elemental compositions, technological properties, density, and methane content of coals at different stages of methane generation in terms of catagenetic changes of coalbed organic substance have been studied. Theoretical calculations of changes in averages values of density of carbon atomic packing in natural formations ranging from lignite to anthracite, graphite, and diamond have been represented. Mechanism of the formation of reverse methane content of anthracites at the expense of carbon restructuring of coal, increase in density of carbon atomic packing, and involvement of occluded methane and radicals of СН3 group in the process of anthracite polymerization has been substantiated.
