This thesis explores the application of the mathematical principles of Holmberg and his collaborators.These principles are described in the book Rock blasting and explosives engineering which aims to demonstrate in a practical way the importance of proper drilling and blasting mesh design. This was completed, first of all, with geomechanical mapping (RMR), analysis of the start to be used, as well as the length of holes and the optimal explosive for the bait and the loading column. This research was carried out at the Santa María Mining Unit of Compañía Minera Poderosa S.A., where it was shown that the diameter change in the starter relief drills from 38 mm to 64 mm and the additional use of 8-foot holes for the 2.5 m x 2.7 m section, contributes to being efficient in every shot. In this same instance, it was demonstrated that, optimally applying the mathematical principles used the amount of explosives use can be significantly reduced, reflected in economic savings per shot. The results obtained with the new design are: the power factor went from 1.23 to 1.15 kg/t reducing a 6.8 %, the advance per shot from 1.51 to 2.10 m increasing a 39.2 % and the linear load factor from 23.24 to 21.02 kg/m reducing a 9.6 %; which translates into a monthly savings on the work front of S/. 21,421.12.
