“Chile already has important underground operations, such as El Teniente and Chuquicamata, and BHP is also considering making Escondida an underground mine. During the construction process of an underground mine, it is possible to encounter some geological problems, such as hot springs, fracturing, high density, or rock bursts. Still, these challenges can be addressed in engineering development.”
