1. Introduction The optimization process aims to minimize the unit cost (€/m3) of the operations that integrate the primary blast, secondary and crushing rock, taking into account pre-established criteria to obtain a lower global cost per m3. In this way, a pseudo-optimal geometry of the blast was generated through the resolution of the model by the Solver Excel tool.
