The object of investigations - carbon massif of "A.F.Zasiad'ko" mine, Donetsk bassin. The aim of investigations - investigation of isotopic compositon of carbon, nitrogen and helium as gaseous componnent of coal in order to establish possible way of methane migration within coal seams. As a result of investigations following task have been obtained: carbon isotopic composition in coal and dessiminated carbonates; spectra of EPR and PMR of coal; the most sensitive radiospectroscopic parameters of different coal composition are paramagnatic centers of carbonated organic matter, the number of molecules of ethilene and absorbed water.
