The results of chemical, proximate and petrographic analysis of coal samples at different coalification stages from various deposits in Russia and Mongolia are presented. Features of the molecular structure of the carbon framework in the organic matter were studied by the solid-phase 13C NMR spectroscopy using the cross polarization with magic angle spinning (CP/MAS). Significant differences in the structure of polycondensed aromatic nuclei were revealed, and the ratio between the pericondensed and catacondensed cycles depending on the degree of coalification was assessed. Correlation analysis was carried out and the relationships between various chemical technological parameters of coals and the indicators of their molecular structure were established. The strongest relationships have been revealed between the aromaticity factor of coals, the fraction of carbon in pericondensed structures, the yield of volatile substances and the reflectance of vitrinite. The identified features of the molecular structure of the organic coal matter and the obtained regression dependences can serve as the physicochemical basis when selecting coals for obtaining polycondensed aromatic substances for
