Abstract: Relevance of the work: to establish a rational direction of industrial use of coal in a particular industry it is necessary to assess their energy potential. Objective: To establish a higher calorific value of coals depending on their stage of metamorphism. Methods: technical, element, petrographic analyzes, determination of heat of combustion in a calorimeter bomb. Results: In a calorimeter installation were measured the values of the highest calorific value of combustion of coals of different metamorphic stages. The analysis of the data showed that the amount of the highest combustion heat is dependent on stages of metamorphism of coals and their elemental composition.

Key words: coals stages of metamorphism elemental composition calorific value of coals calorimetry
