Geotechnical requirements of subsurface repositories in mines, rock and salt caverns for interim or final disposal of hazardous wastes
Abstract The storage of hazardous wastes in subsurface facilities, i.e. in mines, salt caverns and hard rock caverns, offers a high degree of security potential. This is because the contaminants are entombed in geological formations of the deep underground a long way from the biosphere. In order not to prejudice the security offered by the geological barriers certain geotechnical demands have to be met with respect to stability, tightness and sealing in the construction of these subsurface waste repositories. Furthermore, prior to their emplacement, wastes have to be conditioned to exclude the possibility of reactions between the wastes and between the wastes and the surrounding material, e.g. rock or lining. Depending upon the intended function of the subsurface facility, i.e. for interim or final storage, different demands are pertinent with respect to the emplacement technology and the facility seal. In the following paper the geotechnical security objectives for subsurface repositories for interim and final storage are discussed and technical concepts for the construction and operation of mined, salt and hard rock caverns presented. The possibilities for using current mine operations and abandoned underground spaces for the storage of hazardous wastes are discussed.
