Tectonics and stratigraphy| Zusammenfassung: | Increasing requirements for monitoring and environmental protection, especially in the coal-mining regions of Ukraine, where a large number of industrial enterprises are concentrated, necessitates new scientifically based methods for predicting the content of toxic and potentially toxic elements in the rock mass that mined from the mines, in the coal wastes. and coal upgrading, as well as the impact of the coal industry and heating enterprises on the ecological state of the environment. For this purpose it is necessary to have data about concentration, character and peculiarities of the distribution of toxic and potentially toxic elements, including lead in the coal seams.The article presents the results of research covering the whole territory of one of the most studied geological and industrial areas of Donbas – Donetsk-Makiivka for the period from 1983 to 2014. The peculiarities of the distribution are considered and the character of lead distribution in 52 coal seams is determined, the weighted average concentrations of this element are calculated both in the coal of the main working seams and in 7 suites of the middle and upper series of coal period.It is proved that the accumulation of lead in the coal of the main working seams of the Donetsk-Makiivka geological and industrial area is polygenic and polychronic. The change in its concentration in section and area is mainly due to tectonic and facies features of coal-bearing strata formation, controlling the petrographic composition of coal, hydrodynamic regime of the peat accumulation basin, lithological-facies composition of the immediate and main roof of coal seams, coal fracturing and rocks that contain this coal. |
