The negative impact of man on the environment is noticeably manifested when mining in an open way, in which the prevailing natural landscape is completely disrupted. The object of the study was the Starooskolsk-Gubkinsky iron ore region of the Kursk magnetic anomaly. For the mining technical stage of reclamation of disturbed territories with unsatisfactory growing conditions, common pine (Pinus sylvestris L.) was chosen for research. In the results of studies of post-technogenic areas, elements of mineral nutrition, water, physical and chemical properties of substrates were determined. According to these data, the particle size distribution of such dumps contains from 6 to 43% of silt particles (less than 0.001 mm). Water-soluble salts in the substrates contain a small amount, and the dry residue ranges from 0.12-0.6%. The amount of organic matter is small and reaches only 0.13-0.66%, and mobile phosphorus 1.8-2.0 and exchangeable potassium up to 16 mg / 100 g. These substrates have a high connectivity, showing degree of bonding between individual particles. According to the analysis of the data, the substrates at this object of study are characterized by water-physical properties that make it difficult for tree species to grow

Abstract. The cost of energy has increased significantly for the industrial enterprises over the recent years, due to an increase in the electricity tariffs and the changes in the rules of the electricity market. Tariffs for electricity sold to consumers, differentiated according to various parameters, one of which is the voltage range. The higher the voltage range, the lower the tariffs, and thus, the consumer pays less for the supplied energy. Currently only for big consumers made energy supply "direct input" through the construction of an overhead line (OL) with a nominal voltage of 110 kV or 220 kV. However, it is advisable to consider the issue of power supply efficiency of big and medium-sized industrial enterprises based on the "direct input". The questions of voltage level study based on empirical formulas are considered in the article, expressing the dependence of the voltage from the transmission distance and the amount of transmitted power. It was proven that these formulas give a large spread, so intermediate voltage classes 35 kV and 110 kV, which compared with the traditional option of power supply on the basis of the cable line 10 kV, have been selected. Based on the technical and economic calculations it has been proved the value of the transmit power and length of the line at which the power supply of industrial enterprise on the basis of " direct input" with a nominal voltage of 110 kV becomes effective.
