The paper provides information on the investigations of carbon isotopic ratios in coal, chemical
content, and carbon isotopic characteristics of carbon dioxide and methane in coalbed gases
of the Carboniferous beds of the A. F. Zasyadko coal mine (Donbas). It is established that the
coalbed gases originated from kerogen-3 due to its thermal degradation. Extrinsic methane and
carbon dioxide in some coalbed gases were detected. Probably, they were migrated from deeper levels of the Donets coal basin and (or) an endogenic source.
