PECULIARITIES OF FORMATION OF CHEMICAL COMPOSITION OF THE EASTERN DONBAS MINE WATERS FOR A CENTENARY PERIOD

Abstract

Regularities of formation of chemical composition of mine waters in the Eastern Donbas are studied in the space of the centenary since twenties of 20 century until the year 2010. In all, more than 1500 analyses have been used. The largest changes of chemical composition are recorded in 40-th and 50-th years, and after mass liquidation of coal mines in the region. The carrying away of dissolved substances reached its maximum in the year 2010, what caused an intensive pollution of natural waters. The four main directions of transformation of mine waters’ chemical composition have been singled out in the region and interpretation of their genesis given.
