Sažetak

Underground exploitation of dimension stone is spreading lately for three main reasons; economy, organisation and environment. Moreover, underground openings can be used for many purposes.
Underground exploitation is different from surface quarrying only in the first stage, the removal of top slice, descending slices are worked as in conventional quarries.
In underground stone quarries, stability problems require adequate studies in order to avoid expensive artificial support measures, The article presents numerical analyses of an underground stone quarry made using of the finite difference code FLAC.
