Abstract: The study is devoted to the analysis of the state of land dump Korkinskiy coal mine, located on the industrial territory of the Chelyabinsk region. Monitoring the state of technogenic landscapes near megalopolises is of current environmental and sanitary-hygienic importance. Used field and laboratory research methods. The data on the composition and properties of the initial and current state of the components of the natural system of the territory for the extraction of brown coal by the open method after the biological stage of recultivation is presented. It is revealed that overburden rocks have a high degree of chemical and biological weathering. The embryonic soil profile has an initial stage of differentiation into horizons. The fairly high content of humus, microbiological activity in it indicate the intensive flow of humus-accumulative process in it along the zonal black soil type. The degree of its development in the first three reclaimed terraces of the blade is different. Soil-ecological indices and bonitet scores of embryonic soils, compared with the black soil adjacent to the quarry, remain low. For more effective passage of the biological stage of reclamation, it is necessary to limit or completely prohibit cattle grazing until the reclamation is completed. To ensure a favorable ecological condition of the object of recultivation, to reduce its adverse impact on the environment, it is necessary to carry out recultivation on all terraces of dumps.
