The article presents the results of research on sediments from underground waters of hard coal mines of the Upper Silesian Coal Basin (USCB) carried out in the Department of Environmental Monitoring of the Central Mining Institute in Katowice (Poland). In the sediments, barite containing radium was found. This barite, as a mineral originating from underground waters, co-occurs with barite coming from gangues, present in hard coal deposits. The conducted mineralogical, physicochemical and radiometric studies allowed one to assess the properties of the underground water sediments. The assessment of the properties of the examined sediments takes into consideration the concentration of barite in order to separate its forms of occurrence, particularly in a relation to the concentration of radium. |
