The exploitation of mines or quarries can be performed underground in open pit or in a mixed way, depending on the location and morphology of the mineral deposit. The technical and economic viability of a mining unit depends on the correct definition of the operation method and the blasting geometry and techniques, as well as human resources and technology to install. These aspects vary according to the type of operation (underground open pit or mixed).

In the engineering project for mines and quarries, whether underground, open pit, or mixed are taken into consideration the mineral deposit’s characteristics, the rock formations and the site of the unit installation, being essential to use of digital tools that assist in defining optimized geometries for blasting and predicting the evolution of space exploitation. Thus, it is possible to maximize the recovery of the ore and, consequently, the technical and economic feasibility of the mining enterprise.
