Measurement and evaluation of the water and the salt solutions occurring in the exploitation of rock salt, potash or copper shale deposits in the Bernburg Hauptsattel or the Sangerhaeuser Revier in order to assess the long-term safety of repositories

For a thorough assessment of conditions governing the occurrence of salt solutions or water in a repository in the Zechstein, i.e. in the salt formation and at its boundaries, data measured in other mines developed in this formation can yield valuable information. The studies reported were based on geological, hydrogeological, geochemical and geomechanical data collected for more than 50 inflow areas or salt solution bearing areas, covering approx. 15,000 chemical or physical analyses from which the data were derived describing the characteristics or development of inflow streams with time. In addition, the mapped inflow streams were evaluated with a view to the geological and hydrogeological and the geomechanical conditions of origin, as well as engineering impacts. (DG)
