Did you know?Noranda started using plasma blasters in their mines in lieu of dynamite in the very early 80's. I remember it very well. Noranda was considered one of the world's most technologically advanced mining companies in the world back then. Plasma blasters could blow a hole in a rockface underground the size of a Volkswagen camper without leaving the air full of noxious fumes like dynamite did. Work could continue uninterrupted. That's a fact.
