The realities of different open mines that are characterized by carrying out and extracting large amounts of ore, as well as generating large economic investments, allow for a geotechnical design that is sustainable and allows maximum profitability in the project; therefore, in the geotechnical design stage and the consideration in the analysis of the optimal bench and berm, as well as the optimization for the design of the global slope angles and inter-ramp slope. However, there may be excavated areas due to old mines that have already been mined and that have not identified voids that at the time of mining lead to instability at the time of deepening. For this, this publication presents the methodology of design in an open pit considering geotechnical domains and recommended design suitable for the different geological domains presented, as well as the mining strategy for the optimization of the appropriate critical width for the crown pillar at the time of the interaction.
