ABSTRACT
Purpose. To conduct a comprehensive assessment of the coal seams’ quality on the site “Uspenovskyi No 2” in Lozovskyi coal-bearing area of the Western Donbas industrial district; establish their grade composition according to current standards, and find the main directions of their rational use.
Methods. The research is based on the methods of analysis, synthesis, and statistical treatment of indices followed by the prognosis and refining of coal quality characteristics.
Findings. We analyzed the reserves of fuel and energy resources of Ukraine and evaluated chemical and technological characteristics of coal seams for the site “Uspenovskyi No 2”. Statistical treatment of the data allowed to reveal the relationships between the quality indices and establish lateral and stratigraphic patterns. The grade composition has been specified and the ways of coal rational use have been considered.
Originality.The distribution patterns of coal quality parameters have been established for the site “Uspenovskyi No 2” in Lozovskyi coal-bearing area of the Western Donbas by statistical analysis. In particular, statistical significance of the reduction in the vitrinite reflectance index and combustion heat, as well as the increase in volatiles output with increasing depth has been confirmed.
Practical implications.Detailed statistical analysis of coal quality allowed giving recommendations on rational use and implementation of clean technologies of coal processing at the stage of geological exploration.
Keywords: coal, chemical and technological parameters, ash content, sulfur content, combustion heat
