STRAIGHT FORWARD DRILLING WATeR-pOWeReD DRILLING ScALeD up IRON ORe pRODucTION IN LKAB mINeS When LKAB scaled up their production in 1990, they needed a drilling technology that could provide 60 meter long blast holes with a deviation of max 1.5% and to a lower energy cost. Today, all production drilling at LKAB is operated with the water-powered DTH hammer from Wassara. A total of 18 million meters blast holes have been drilled with Wassa
