Savchuk W. The Lower Carboniferous Coals of Ukraine: their composition, quality and main directions of it rational use

The paper is devoted to the solution of urgent problem of determination the regularities and main reasons of changing of the composition and quality of the Lower Carboniferous Coals of Ukraine on the area and in the stratigraphic section of carboniferous stratum, of finding it relative technological power value of rational use of coal. On the base of new methodological concepts of data interpretation about composition and quality of coal, the main criterions that control the consumer value of coal are determined. It were established the peculiarities of geological factors of variety of coal quality, considered the lateral and stratigraphic regularities of their changes. On the results of complex estimation of technological characteristics of coal, the directions of their ra-tional use were established. Proved, that coal of the forth grade, is essentially differs on the base of those charac-teristics, which determine the efficiency of it power and technological use. Formulated the conclusion about the originality and step forward of coal-formation on the territory of Ukraine. This conclusion widens the theoretical idea about regularities of changing of coal composition and its quality and deepens the conceptions of historicity in the development of coal-formation. The application of complex estimation of coal composition and its quality and generalization the ob-tained data on developed system let us to solve an important practical problem of rational coal use.
