PECULIARITIES OF THE FORMATION OF NATURAL AND MAN-MADE LANDSCAPES IN THE DNIEPER BROWN COAL BASIN
Coal mining leads to the formation of new engineering-geological, geochemical, hydrogeological and biological conditions that are irreversible environmental changes, and are expressed in the disturbance of the relief, landscape, pollution of the atmosphere, soil, groundwater and surface water. After the coal seam is mined, the removed rocks are partially or completely returned to the quarry, despite this, this type of coal mining, to the depth of development, changes the upper layer of the lithosphere and the hydrosphere (groundwater). Open-pit lignite mining creates natural and man-made areas up to 100 m deep on the surface of the lithosphere, which is reflected in changes in the relief and creation of artificial reservoirs after coal deposits are mined. The processes that occur in the natural and man-made landscapes of coal mines complement and to some extent change the course of previous geological processes, but so far their environmental impact has not been recorded. Despite this, it is the processes activated by coal mining in the upper horizons of the lithosphere that are crucial for the formation of a technologically loaded environment and have a negative impact on the environment. Newly formed natural-technogenic and technogenic landscapes are included in the endogenous and exogenous processes of the planetary level. The geological process of structure formation has undergone significant changes due to mining operations, which have an impact on the depth of open pits. And especially on the flooding of abandoned quarries, which significantly changes the redistribution of water on the surface of the planet and in the upper layers of the lithosphere. The processes that occur in the natural-technogenic landscapes of coal mines complement and to some extent change the course of previous geological processes, but so far their impact on the environment has not been recorded. Despite this, it is the processes activated by coal mining in the upper horizons of the lithosphere, especially aquifers, that are decisive for the formation of a technogenically loaded environment and have a negative impact on the environment.
Key words: Dnieper brown coal basin, technogenically loaded environment, coal mining regions, natural and man-mad landscapes.
