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