【 摘 要 】

The authors of the paper have established the geochemical features of the composition of underground waters and regularities of their formation in the areas of the liquidated coal mines of Russia and Ukraine. It is shown that the mine flood resulted in the formation of technogenic waters which geochemical specificity originates in the feeding field and is transformed in the direction of the filtration flow. It depends on the geological structure of sedimentary basins and the presence in the coal and supra-coal beds of the marine, salt-bearing and freshwater groups of geological formations. The water types are distinguished characterizing the conditions and processes of their formation that may be the regional markers in the hydrochemical and geological constructions. The technogenic waters influenced the safety of the underground waters, sources of water supply of the regions, and surface water channels. The pollutions are of local character in space.
