This thesis discloses the technical tests carried out on advance fronts of section 4.0mx 4.0m in the American Unit of the Mine Company Casapalca SA, for which the model of the drilling and blasting mesh was redesigned, adopting a smaller drilling diameter of 45 mm. The results obtained show an increase in advance per shot of 7%, optimizing the advance factor in 21% and a saving in blasting costs of 14%. All the tests carried out were accompanied by the application of controls and operational discipline, in order to avoid cut shots and blown shots.
