Abstract. Five mining objects located on the territory of Sverdlovsk region were analyzed. These objects represent good examples of disturbed areas. The territories of the Pyshminsky-Klyuchevskoe and Berezovsky mining submittings are used for active building development at the present time. These towns are the satellites of Ekaterinburg city. Former mining submitting areas of Levikhinsky, Bulanash and Degtyarsk fields were abandoned and currently require large economic investments for remediation and elimination of environmental harm. Disturbed lands of the Sverdlovsk region amount is 2.7 % of the total area of the subject of the Russian Federation (1943,07 sq. km). Comparative analysis of land use showed a negative trend. The amount of lands disturbance in the Sverdlovsk region is higher than in neighboring regions due to the high rate of economic development. In the Tyumen and Kurgan regions, the proportion of reserve land is higher than the share of the industrial lands. The most comparable results can be obtained by comparing the Sverdlovsk and Chelyabinsk regions. Disturbed lands are present on the industrial lands and agricultural lands with the equal degree. In Sverdlovsk region the main negative land processes are chemical contamination and land disturbance. The analysis of the disturbed territories’ building development shows that despite of the economic benefits, the multi-storey residential building can not be used on these areas like it takes place in Berezovsky and Verkhnyaya Pyshma. It is necessary to impose the restrictions to the town planning regulations for these territories and use these areas for low-rise constructions or recreation. The economic development degree of the settlement should not increase the risk of technogenic catastrophes.
