Geotechnical investigations of closing systems in a final storage mine

In the Asse saltmine of the GFS Research Centre for the Environment and Health GmbH, which is now being used as a research mine, two large underground experiments on closing systems are at present being carried out. In the first large experiment ('Dam building in rock salt'), the mechanical and hydraulic functioning of a dam construction as final storage of waste materials is being explored. In the second of these large experiments 'Thermal simulation of underground roadway storage - TSS', the mechanical and hydraulic reaction of a roadway made of fine salt with roadway convergence accelerated by heating of the stored substance is the object of the exploration programme.
