Abstract

APPLICATION OF HYDROGEOCHEMICAL AND GEOPHYSICAL METHODS IN ASSESSMENT OF THE INFLUENCE OF COAL-MINING WASTE DUMPS ON HYDROGEOLOGICAL ENVIRONMENTAbstract. Coal-mining is a source of the bulk amount of mine waste, which bring about complex environmental problems, particularly related to groundwater contamination. Long-term potential pollution of mining waste to the aquatic environment results mainly from the chemical composition of coal mining waste and their transformation products. Hydrogeochemical methods were used to assess the impact of the leachate from coal mining waste dumps on contaminant distribution in groundwater. The results of hydrogeochemical observation were compared with geophysical investigation obtained at the same time. The geophysical research were carried out using georadar method, electromagnetic profiling and resistivity imaging technique. The measurement profiles were designed on the basis of hydrogeological information, especially using maps of distribution of electrolytic conductivity. Both hydrogeochemical and geophysical methods complement each other and allow for comprehensive assessment of groundwater contamination.
