Prykhodchenko D. Rules of changes in composition and grade of coal in Lozova district (Western Donbas)

The thesis has solved topical scientific problem concerning determination of rules of changes in composition and grade of coal of Middle Carbon in Lozova geologic district of Donbas with recommendations concerning rational industrial use of coal. It has been determined that according to the area, coal of Bashkir age experiences west-to-east increase in maceral group of vitrinite against the background of decrease in maceral group of inertinite coinciding with rules of its changes determined for coal of Lower Carbon; inverse regularity as for changes in petrographic composition has been identified for coal of Moscovian stage. Genetic features of coal content and grade have been determined. Classification and codification have been performed in accordance with home and world standards. Producibility of coal deposited within the region under analysis has been estimated.
