Особенности взаимодействия подземных и поверхностных вод в зонах дизъюнктивных тектонических нарушений (на примере Восточного Донбасса)

Abstract

Eastern Donbass, where coal has been mined for over a century, has become a natural-technogenic system (NTS), affecting all components of the natural environment. Among the elements most affected by it are groundwater and surface water exposed to mine waters. The state of the NTS is due to the interaction of technogenic and natural factors such as the geological structure of the territory. For many years, the environmental assessment has taken into account the organized discharge of mine water. At the same time, this region is characterized by widespread development of disjunctive tectonic faults. The hypothesis seems logical that not only the treatment facilities of closed coal mining enterprises, but the faults and associated fracture zones are channels for the drainage of mine water and deep highly mineralized solutions to the surface, where they are unloaded into the river network. Studies carried out in one of the promising areas, where drainage of groundwater takes place through fractured rocks developed along the fault displacement fault, showed their significant impact on the composition of the surface waters of the river Small Nesvetay. Taking into account the very complex tectonics of the Eastern Donbass, it would be logical to assume a similar influence of other numerous disjunctive structures. Their study will contribute to a comprehensive assessment of the region's environment and the adoption of management decisions, and the development of effective measures for water purification and stabilization of the ecological and social situation in the region.
