A thermogravimetric study of the inertinite fractions of coal from different stages of metamorphism was carried out in inert and oxidizing environments. It was shown that with an increase in the degree of metamorphism of inertinite fractions during their pyrolysis in an inert environment within temperature range 360-900 degrees C, the temperature of the onset of mass loss increases, the rate of the main period of resin and gas release decreases, and the maximum thermochemical decomposition of coal in the DTG curve shifts to higher temperatures. It was established that in the series of metamorphism of the studied inertinite samples, their reactivity with respect to oxygen decreases, which is evidenced by an increase in the temperatures of the stages of the oxidation process: the ignition temperature of coal particles, the temperature at which the maximum oxidation rate is reached, and the final temperature at which burnout of the coke residue occurs. An increase in the values of these parameters is associated with an increase in the aromaticity index f(a) of the organic mass of the samples and a reduced yield of volatile substances.
