At the same time, they adopted the national green taxonomy, i.e., a strategy that allows determining on a scientific basis the classification of economic activities for decarbonisation with the involvement of green investments and bonds [14][15][16][17][18]. This corresponds to the main principles of the European Green Deal and the adopted environmental policy of the EU in the context of sustainable development.…”

The features of the distribution of toxic elements in the c1 coal seam of «Blahodatna» mine field are considered. The research aims to establish regularities in the distribution of toxic elements in the coal seam c1 of Blahodatna mine of Pavlohrad-Petropavlivka geological and industrial area of Donbas. Samples were taken from mine opening (reservoir samples, selected by the trench method and from duplicates of drill core personally). Content of toxic elements was determined by quantitative emissive spectrum analysis. The values of the main descriptive statistical indicators were calculated. With the aim of identify the composition of the geochemical associations, correlation coefficients (r) were calculated between the content of the toxic elements. In a single geochemical association united elements in which the relationship between the content is described by the correlation coefficient that exceeds 0,5, with a significance level of at least 95%. As a result of the performed studies, maps of the isoconcentrate of toxic elements and maps of the regional constituent of their contents by the area of the mine field were constructed. Linear regression equations are calculated between the concentrations of toxic elements and the main technological parameters of coal. Analyzing the result of statistical processing of geochemical information and geological and structural characteristics of the coal seam c1 of «Blahodatna» mine field allowed us to establish, that the formation of the association of cobalt, nickel, vanadium, lead, chrome and manganese is associated with the enrichment of contact zones of the coal seam by these elements and is genetically is due to influence of adsorption and reductive-oxidative barriers on the migration of matter during the diagenesis and catagenesis of coal-bearing series. The main scientific importance of the results of the performed studies is the establishment of genetic causes that have a significant effect on the distribution of toxic elements in coal seam of c1.

Spatial distribution of arsenic, mercury, fluorine and beryllium in the c1 coal seam of «Blahodatna» mine field are considered. This research associated with increasing requirements for environmental protection, which necessitate the need for new scientifically based methods for predicting the content of toxic elements in rock mass that extracting by mines and mining waste and coal enrichment. The aim of the research is to establish features and regularities in the distribution of arsenic, mercury, fluorine and beryllium in the coal seam c1 of Blahodatna mine of Pavlohrad-Petropavlivka geological and industrial area of Western Donbas. Maps of the isoconcentrate of arsenic, mercury, fluorine and beryllium and maps of the regional constituent of their contents by the area of the mine field were constructed. Linear regression equations are calculated between their concentrations and the main technological parameters of coal. On the basis of the results of statistical processing of geochemical information and geological and structural characteristics of the coal seam c1 of «Blahodatna» mine field allowed us to establish, that the beryllium is the only element mainly associated with the organic constituent of the coal layer. Cumulation of its main part occurred in the process of peat accumulation. Close correlation connection between mercury and arsenic with sulfur and the analysis of the spatial location of the anomalies of these elements with the geological and structural features of the seam indicates the accumulation of these elements at the post-sedimentation stage of the formation of coal deposits and their genetic connection with the tectonic disturbance. Moreover, if large disturbances basically have a role of supply and transit channels, then minor disturbance and make a controlling function. Close direct correlation relationship of fluorine with coal ash and analysis of the constructed maps indicate that its predominant accumulation during the formation of a paleo-turfary in the composition of layered aluminosilicates. The main scientific importance of the results of the performed studies is the establishment of geochemical associations and genetic causes that have a significant effect on the distribution of toxic elements in coal seam of c1.
