Abstract

Toxic elements are one of the main sources of environmental pollution that negatively effects on human health. Research in this direction is conducted to reduce the degree of negative effects and additional pollution of the environment. Increasing requirements for environmental protection and influence accounting of coal-mining enterprises on the ecological situation stipulates the need for new scientifically grounded methods for forecasting the content of toxic elements in rock mass, mining waste and coal enrichment which is mined by mines. In the article, the results of investigations of toxic elements in coal layer с8в of «Dniprovska» mine field are considered. The research aims to establish regularities in the distribution of toxic elements in the coal layer с8в of mine field of «Dniprovska» of Pavlogradsko-Petropavlovskiy geological and industrial region of Donbass. As a result of the performed studies, the content variations and average concentrations of toxic elements in the coal of the layer were established, maps of the isoconcentrate of toxic elements and maps of the regional constituent of their contents by the area were constructed. The constructed maps are the factual basis for the long-term forecast of the concentrations of toxic elements in the rock mass that extract by the mine. Linear regression equations are calculated between the concentrations of toxic and potentially toxic elements and the main technological parameters. These equations can be used for short-term and medium-term forecasting and controlling the contents of toxic elements in the extracted rock mass. In its turn, long-, medium- and short-term forecasts of toxic elements concentrations in extracted rock mass should serve as the basis for technological solutions aimed at reducing their content in coal mining products, products and waste coal. Analysis of the result of statistical processing of geochemical information and geological and structural characteristics of the layer с8в of mine field of «Dniprovska» mine allowed us to establish, that association of mercury and arsenic is due to their genetic connection with the sulfide mineralization of fractured zones of tectonic nature. It is proved that beryllium is the only element, mainly associated with the organic constituent of coals. 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 layer of с8в.
