Tectonics and stratigraphy| Summary: | Increasing requirements for environmental protection in the coal mining industry in Ukraine stipulates the need for new scientifically grounded methods for forecasting the content of toxic and potentially toxic elements in rock mass, mining waste and coal enrichment which is mined by mines, as well as the environmental impact by enterprises of heat power industry. For this purpose it is necessary to have data about concentration, character and peculiarities of the distribution of toxic and potentially toxic elements, including mercury and chromium in the coal seams. The studies covered all territory of one of the most studied geological and industrial areas of the Donbas - Krasnoarmiiskyi. In the article, peculiarities of the distribution of mercury and chromium are considered and character of their spreading in the coal seams are established, weighted average concentrations in the coal of the main seams and suite are calculated. Hystograms of distribution of mercury and chromium content in coal seams, as well as dendrograms of clustering results by weighted centroid method of coal seams by their content, have been constructed and analyzed. The accumulation of mercury and chromium in the coal seams of the district is polygenic and polychronic. The main form of finding these elements in the coal seams is sorbed (on clay minerals and fusenized microcomponents), and for mercury also sulfide (in epigenetic pyrites). |
