Abstract
Coal from the Usinsk deposit of the Pechora coal basin was studied using a set of chemical and physicochemical analysis methods (technical and elemental analysios, ash composition analysis, thermogravimetric analysis, IR and 13C NMR spectroscopy etc .) to evaluate coal composition. It was shown that coal belongs to the medium metamorphized group and is characterized by aromaticity factor 71 to 77 %. Total sulphur content in coal is within the range 0.3 to 2.8 %, the mineral part of coal is represented mainly by the compounds of silicon and aluminium.
