Mining

Underground mining. Ore is extracted from LKAB's underground mines by means of sub-level caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader.
