The open-pit method of mining the Azeiskii deposit of brown coals is ecologically hazardous and has a negative influence on the environment. It is established that, according to the chemical properties, soil-ground of the deposit under investigation has low nitrogen enrichment, and a small amount of humus, gross phosphorus and the sum of absorbed cations. We determined the mean concentrations of chemical elements in soils (clarke) which have high indicators and are allowable for the region’s soils. The content of strontium, chromium and lead in soil-ground of the open-pit coal mine is less than a clarke. It is found that the temperature curves of soil-ground for different areas of mining of the Azeiskii open-pit brown coal mine have a similar configu ration, and the differences in temperature regime depend on size-grade distribution. A study of the physicochemical properties and thermal regime of ground-soil of the dumps with total destruction of ground and soil cover revealed the development of re habilitation stages
