One of the main mechanisms that determine the deterioration of salt stability is the occurring of fractures as a result of the influence of mining pressure. Aspects of rock salt cracking can be observed both in situ and laboratory tests on rock samples collected from the mining works. Cracking parameters are determined for different conditions: age pillars, excavation technology, how has the bearing size, depth of mining and other random aspects. Geomechanical assessment of underground workings made in rock salt m...
