Ecological and Hydrogeological Challenges of Coal Mining Regions of Ukraine

Ecological and hydrogeological conditions of the region are very difficult, which is due to it tectonic features and lithological composition of water-bearing rocks. Feeding aquifers and complexes lying near the earth surface, occurs mainly due to precipitation and water flow from the horizons above. Aquifers coal areas of Donbass affect the development of coal seams at different depths in the coal massif and are transformed into waste space of workings in connection with the change of hydrogeological mode after man-made exposure. Aquifer horizon of coal-bearing areas represent, in most cases, a system of complex pools fractured waters, which complicate the development of minerals in mining. Aquifers are associated with sandstones, limestones, less often, siltstones.
