The Influence of Horizon Xiv’s Exploitation on the Stability of Surface at Slănic Prahova Mine

Abstract The exploitation of the XIV horizon, in two slices, across entire mining perimeter Slănic Prahova Salt Mine until end 2059 will result amplification surface subsidence, already affected by operations Victoria, Cantacuzino, and Old Mines. Systematic annual monitoring ground deformation has been conducted since 2004 through geometric leveling along selected representative alignments, which were utilized to forecast temporal evolution subsidence impact horizon. Furthermore, 3D numerical modeling was employed estimate displacements.
