The scientific novelty of this study lies in a comprehensive analysis of the physical and chemical properties of brown coal of the Kuznetsk deposit using modern research methods.Data on elemental composition, ash content, moisture and volatile matter yield of this coal are systematized and presented.Particular attention was paid to the study of the influence of functional groups on the reactivity of coal, which had not previously been studied in such a detailed form for this deposit.This research uniquely unveils and details the chemical structures of humic acids, offering a more
