Abstract: Three samples of coal technology brands LV mined at various enterprises of Kuzbass are described using complex chemical and physico-chemical methods of analysis. The study found that the coals of the same technological brands may differ in their physical and chemical properties. It is shown that coal sample number 3 has a larger index of vitrinite reflectance (Ro, r = 0.63), characterized by a lower atomic ratio H / C (0.86) and it has a higher aromaticity organic mass (fa = 0.69).
