Abstract:

Purpose. To identify the features of the petrographic composition of coals, to determine their typical structure and set the areal and stratigraphic patterns of change to justify the ways of rational coals use.

Methodology. Estimation of advanced petrographic composition of the coal organic mass and mineral admixtures has been made by briquette-polished sections in reflected light, and the micro-components characteristics, micro-structure and restoration of coals has been held in thin sections in transmitted light. Classification VSEGEI is adopted as the basis of the petrographic coal typing, coal bed typing on petrographic composition has been made by the method of Volkova I. In contrast to prior studies in which petrographic composition was studied at the level of petrographic groups, for the first time the features were described and the data on the distribution of individual macerals have been summarized.

Findings. An integrated approach to the study of the petrographic composition lets us to identify the genetic coal characteristics of south-western part of the Lvov-Volyn basin, determine their typical macerals’ composition and establish regional and stratigraphic patterns of change.

Originality. Methodological approach of the coals petrographic composition study is improved, that allows predicting technological and energy coal value more accurate as well as determines the main directions of their use. Genetic coals characteristics have been identified, that enables us to highlight key industrial coal types which are typical of Lower Carboniferous coal accumulation of Ukraine. Genetic coals characteristics have been identified, that lets us to select the main industrial coal types which are normal for Lower Carboniferous coal accumulation of Ukraine.

Practical value. For the first time we have given the extensive petrographic characterization of coal seams of Southwest part of Lviv-Volyn basin and identified their typical macerals’ composition, the regularities of change in the stratigraphic section have been established as well as in area of distribution of the coal seams.
