“…A close connection of quality parameters and mine water pollutants with the nearby river water parameters and with the quality of well water used by local communities for water supply was found [28]. Under the impact of mine waters and dump area technoginic flows of dissolved substances, the chemical structure of soil is transformed.…”

Lipovtsy coal field mine №4 processed north-western reserves of Lipovtsy field in Primorski Krai (Russia). In 1997, the mine was declared unprofitable and was abandoned by natural flooding with no arrangement of mine water discharge and in 2005 it was fully flooded. The main sources of pollution in the studied area are spoil heaps (mine wastes), underspoil filtering waters and mine waters which are being discharged on the surface after finishing of "hydraulic funnel" artificial support. The study of technogenic landscape of abandoned mine industrial area showed that its morphologic form is dominated by spoil heaps. Soils located near mine waste body differ from benchmark soils by chemical properties and size distribution. The influence of active hydrochemical mine and drainage water flows is the reason of the above-mentioned variation in soil properties. Results showed that, there exist a high correlation ratios between chemical composition of mine waters and water extracts from soil: Between the alkalinity of mine waters and electrical conductivity of soil water extracts (r = 0.73), between mine water iron content and pH of soil water extract (r = −0.56), between the solid residue of mine waters and electrical conductivity of soil water extracts (r = 0.72), between the mine waters calcium content and electrical conductivity of soil water extracts (r = −0.75), between the alkalinity of mine waters and silicon dioxide content of soil water extracts (r = 0.61), between the mineralization of mine waters and chrome content of soil water extracts (r = 0.73).

“…The coefficient of natural resources usage is in the range from 0.02 to 0.1. The greater part of the extracted resources is returned to the surrounding environment with deteriorated composition and properties [1][2][3][4][5][6][7][8]. At coal mines, there is also an increased level of risk of hazardous and harmful factors to people, which leads to injuries and diseases.…”

The automobile transport as one of significant sources of the increased danger to environment and employees of coal mines is considered in this article. The data of volumes of emissions from the automobile transport of the coal industry in the form of gaseous and solid pollutants into the atmosphere is provided in article. The analysis of influences of various factors which pollute atmosphere by coal dust is carried out in the paper. The reasons of self-ignition of coal in mines and cuts as the source of release of gaseous substances, which pollute the atmosphere, extending to considerable distances and make negative impact on adjacent territories and nearby settlements, are given.
