This research was born as a result of the problem identified in one of the development tasks in the Unidad Minera Poderosa, located in the province of Pataz - Trujillo, dilution. Assessing the optimal percentage of dilution is a problem that has been taking place, since the work area is not being properly characterized. Standardizing drilling meshes is usually a mistake that almost all mining companies make, which is why this study is carried out with the aim of proposing a new drilling mesh according to the characteristics of the rock in which we find ourselves, in order to carry out an efficient design we will use two mathematical models that are widely used, but not merged. The first model is referred to Holmberg's proposal for the design of fronts, he proposes that we divide the front into five parts, in this way we can optimize and properly distribute the fellings. The second model is proposed by Pearse, which allowed us to find the burden and then the spacing that each hole should have in the mesh. Both theories will help us to carry out the pertinent and optimal calculations for a perforation mesh design, after which the JK SimBlast program will be used to design the proposed perforation mesh and analyze the damage zones, the acquired tonnage, and the existing dilution.
