Purpose. The aim of the research is to identify the main regularities of formation of chemical composition of mine waters in the Eastern Donbass for the 100-year period and to assess their role in contamination of ground and surface waters in the region. Methods of researches. Interpretation of the data using the standard methods of mathematical-statistical analysis of information and original digital computer technology of classification of multivariate observations AGATE-2 (G-method). This technology allows you to highlight similar taxa in the absence of a priori information (task without a teacher), use dependent signs, high light taxa at various levels, to assess the similarity between taxa and informative signs. Results of researches. The coal industry has a significant impact on the environmental status in the Eastern Donbass. A detailed analysis of the chemical composition of mine water to nine time intervals for the 100-year period showed that the process of personnel changes is undulating in nature. The intensification of the processes of oxidation, leaching and dissolving discovered after periods of flooding of mines (in the post-war 40-e-50-IES and after the Elimination of mines in the 90-ies). It is in these times of mine waters most intensely polluting natural waters in the region, there is a sharp increase in salinity and especially sulphate iron and various metals. Takeaway mine waters on the surface of the solute reaches 413 thousand tons/year. Four main types of (direction) changes the chemical composition of mine waters. The genesis of the first type is associated with the influence of intensive processes of oxidation of sulfides and sulfur contained in coals and enclosing rocks. The second type is caused by the weakening of the oxidation and the beginning of the influx of chloride in ground-condensation from water-carbon phase. There is a possibility of detection within East Donets Basin oil and gas fields, particularly in Gukovo-Zverevskom coal area. Summary. Found that the mine waters are the leading factor in negative impacts on our environment and cause serious environmental damage in the territory of the Eastern Donbass. This calls for effective measures for the rehabilitation of environmental conditions and improvement of remediation technologies.
