Pietra Serena mining in Fiesole: part III – geostructural-geomechanical characterisation and geomining

The large and deeply exploitated quarry district of the Pietra Serena at Fiesole (Florence, Italy) was worked out through, centuries with no design or any preliminary investigation. In this paper, we characterize the Macigno stratigraphic succession outcropping in the Fiesole hills in terms of geostructural setting and geomechanical properties. We performed stability analysis to verify the safety of slopes of open pits and underground openings, as well as retrospective review of the methods to provide safe environment for Pietra Serena mining.
