The present thesis studies the application of the pre-cut blasting technique in the development galleries of the MARSA subway mine to reduce the overburden in the rock mass, for this purpose the contributions provided by the disciplines of geomechanics, geology, drilling and blasting will be considered. The research was carried out in the eastern cordillera of the Andes, north of Peru in the province of Pataz, where the Batolito de Pataz is located, an orogenic type deposit associated with metamorphism processes and characterized by gold veins, specifically in the area of influence of the activities of the San Andres Mining Unit. With the pre-cutting blasting, a better stability in the development works will be obtained, giving as a consequence the reduction of the overburden in the rocky mass. Geomechanical studies were carried out to designate the type of rock in the area in order to be able to carry out an adequate drilling mesh, as well as the selection of the appropriate explosives to ensure that the rock mass is not affected. Likewise, the costs involved in the design of conventional blasting in contrast to pre-cutting blasting were compared. In a theoretical and quantitative way, it is demonstrated that through the application of pre-cutting blasting it is possible to reduce the overburden in the rock mass and to improve the physical stability of the development works.
