Last month, E&MJ published an announcement from Dyno Nobel on a record underground blast. The text should have read: “The Renard Mine called this stope shot a ‘Mass Blast,’ which was fitting for this large-scale blast. With a total of 265,000 projected tons, 208,000 kg of explosives were used to load this stope shot, including 1,461 DigiShot Plus detonators used for initiation.” The term “projected tons” refers to the total size of the muck pile for this enormous round. Thank you to the E&MJ readers who brought this to our attention.
