Abstract

The acquisition and analysis of the physical and mechanical properties and geostructural character of the rocks, that constitute the excavation front of a argillite's quarry for ceramics near to Sadali, has allowed the geomechanical characterization of the dolomitic rocky mass and the argillitic formation below. The front is, at the moment, potentially unstable, with the collapse of dolomitic rock's blocks on the squares of the quarry. Instability has been certainly caused by a lack of basal support that interests main part of the front extension. The analysis of the dolomitic rocky mass has been faced applying the Classification of Bieniawski, in way to establish its geomechanical quality. The optimal solution to put in safety the front is the restoration of the basal support, through the realization of a terrace and a superficial drain system.
