The aggregate quarries represent over 64% of the total amount authorized in Italy. In this scenario, the demand for an extension of a limestone quarry arises. This thesis analyses the slope stability of the exploitation expansion of the Faraona quarry; the quarry is located in the municipality of Travedona Monate, Varese Province, and it is managed by Holcim Italia SpA. The quarry plan estimates the potential extraction of 6,780,000 m3 of limestone for the next two decades. The mining area is located between Comabbio and Monate lakes. The exploitation involves an outcrop of the Ternate geological formation. Starting from the legislative background that prescribes some technical constrains, this work describes, in particular, the design process of the Faraona quarry.
