It uses the Rhino 100HM raise borer for slot hole drilling in production and also for drilling shafts for the mine infrastructure. At the underground mine, the largest primary gold producer in Europe, raise boring of slot holes replaced drop raises built by drilling and blasting using regular longhole tophammer drill rigs, which had become a
between two and three days to prepare a traditional raise borer for duty, a single operator can tram the Rhino into the mine and be drilling within a matter of minutes. As well as slot raises, the Rhino 100 can be used to drill ventilation shafts, drainage shafts, escapeway shafts, ore passes and back fills.
