Abstract:
Purpose. To estimate potential and actual ecological danger caused by secondary salinization of soils under the influence of the mine waters from technical reservoirs located in West part of the Donets Basin.
Methodology. The estimation of the soils’ state was made by means of the following methods: field methods applied for study of anthropogenic deformed soil systems and for the determination of the negative influence of waste water on the halochemical state of soils (sampling was made by the standard ‘envelope’ method); laboratory methods applied for determination of the chemical compound of soil, its biological activity and pollution indicators (spectrophotometer analysis of mineralization of samples of water and water extracts from the soil samples and potentiometer analysis of an active acidity).
As a result the classification and general characteristic of the negative consequences of coal mining in general and for the West part of the Donets Basin in particular were presented. The results of estimation of water mineralization in the gathering pond “Svidovok” were received. Hydrochemical type of the water was determined. Classification of soils by the type, salinity level and chemism were made. Estimation of secondary soil salinization hazard caused by gathering pond “Svidovok” by Sodium Adsorption Ratio (SAR) and Critical Relation Index (CRI) was made. Results of the soil salinization and alkalinization danger prognosis and actual values of ecological danger of the secondary salinization were analyzed.
