LKAB develops a new mining method
When mining depths in underground mines increase, so do the challenges. Therefore, an entirely new method has been developed – raise caving. This is a major groundbreaking step towards a safer, more efficient mine."Raise caving has been developed for efficient mining at great depth," says Matthias Wimmer, mining engineering manager at LKAB in Kiruna.Rock stresses increase as mining moves to ever greater depth. A more complex geometry, in combination with rock-mechanical challenges, places demands on new, sustainable and innovative solutions for the mine of the future. And, underground,
