The study is directed to assess in advance the safety of the excavation by means of a safety factor FS. The analysis is based on the method of the dowels, passive thrust forces and the definition of the safety factor according to the Mohr-Coulomb's resistance law.esExcavationGeotechnical engineeringRoofGeologySafety factorMining engineeringThrustEngineeringHumanitiesarticle
