Szukana fraza: [Abstract = In the paper the physicochemical characterization of the mine wastes from the LW \"Bogdanka\" hard coal mine is presented. Results of the monitoring, carried out since 1996, cover the chemical composition, abundances of contaminations by metals as well as the concentration of natural radionuclides. It was determined that the monitored physicochemical parameters of the wastes allow their utilization as a mineral material for a vast majority of leveling works, including the prevention against mining subsidence.]
