To further improve efficiency at Codelco’s Radomiro Tomic (RT) copper mine in Chile, the mine team conducted the largest blast in its history, which moved 3.2 million tons of ore. RT superintendent of drilling, blasting and crushing, Angelina Pipon, said, “We have to be efficient and we started to bet on blasting more than a million tons with each blast; later, a million and a half; then two million and now we have achieved the goal of 3.2 million tons.”

Pipon said previously they were blasting up to two or three times in the same day, but now they are aiming for a maximum of three massive blasts per week. “We are moving more material with less interruptions for the day-to-day mining activities,” Pipon said.
