THE MODERN FEATURES OF FORMATION OF CHEMICAL COMPOSITION OF MINE WATERS IN EASTERN DONBASS
In work the analysis of hydrogeochemical information with engaging of a wide arsenal of mathematical-statistical methods is made. Regularities of formation of chemical composition of mine waters of Eastern Donbass by results of synthesis of data for the centenary period are described. The wavy nature of changes of composition of waters is revealed. Four main directions of change of composition of waters before mass elimination of coal mines are allocated and in details characterized. After elimination of mines there was a basic change of the directions and processes of formation of chemical composition of mine waters. Inflow of underground waters from the considerable depths was sharply reduced, the ground and surface water significantly enriched with oxygen and causing development of processes of oxidation come to mines, lixiviations and disolutions are gray and the containing rocks. These waters form extensive streams of pollution of the surface and underground water that demands carrying out rehabilitation measures in all components of a environment.
