The Cantacuzino Mine was mined with small rooms and square pillars, on seven levels, over a period of 27 years, extracting over 2.3 million m 3  of rock salt. Due to the specific geo-mining conditions, the support structures suffered different degrees of deformation, especially the cracking of the ceilings between the first 5 levels. This article presents a 3D finite element analysis, in elasto-plasticity, of the state of stress and strain that generated the deformation of the pillars and ceilings between levels.
