occur, and depressions, ditches, sinkholes, crevices or thresholds are formed. On
the other hand, so-called continuous deformations are formed where the overlying
rocks are plastic, or the mining takes place at greater depths; these result in subsidence troughs being formed whose shape is roughly circular or elliptical and their
morphometric characteristics depend on factors related to the mining methods used
