The article deals with the ecological state of the soil cover of the currently actively developed coal deposits, which are located in the steppe zone of the Central Tuva Basin. Two of them – Kaa-Khem and Chadan – mining is carried out in an open way for more than 50 years, resulting in the formation of quarries and extensive waste rock dump fields. The third field – Mezhegey – has been producing by mine method since 2013. It was revealed that in the areas where open-pit mining is carried out, the maximum concentration of Zn, As, Ni in the eastern and south-eastern parts of the fields, soil contamination by Ni and As was also established. The presented materials can be used to manage the state of the environment and optimize the use of natural resources in the areas of activity of mining enterprises, which will help to reduce the anthropogenic impact on the ecosystems of the dry-steppe region.
