With a high participation, the fifth version of the Summer School of Mine Planning and Operations Delphos 2022 was successfully carried out virtually, organized by the Delphos Mine Planning Laboratory, a joint unit of the Department of Mining Engineering and the Advanced Mining Technology Center (AMTC), in partnership with the Geological Engineering Laboratory (EGL), aimed at engineering students in the mining area.

The purpose of this activity is to bring students closer to the approaches of the different stages involved in mine planning, both open pit and underground mining, making known advanced developments in mine planning and its associated disciplines, both in modeling techniques and in applications in real cases and thereby generate the best productive business.

This fifth version had the participation of more than 100 students belonging to 17 chilean universities and 20 houses of study from Colombia, Ecuador, Mexico and Peru.

On the first week the students saw topics related to geological resource estimation, open pit and underground mine planning, open pit and underground mine operations, planning under uncertainty and simulation for the characterization of rock massif properties. At the same time, they received training in the software produced by the Delphos Mine Planning Laboratory: DOPLER and DSIM. During the second week, students participated in technical talks given by professionals from academia and industry, covering current mining issues and challenges towards the future.
