Super Pit moves a million tonnes of dirt in biggest blast for years back in January 2021

Back in January, Kalgoorlie-Boulder’s iconic Super Pit unleashed its biggest blast for years, moving close to a million tonnes of dirt with the assistance of more than 200 tonnes of explosives.

The blast, which required the drilling of 1780 holes over nine days and involved four days of explosives loading, was part of the east wall cut back which will extend the mine’s life.

The Super Pit is famed for being visible from space but spectators at the blast were much closer at hand with plenty of locals heading to the Super Pit lookout to get a glimpse of the detonation

Described by Super Pit operator KCGM as “unusually large”, the blast took place in a new area of the Fimiston Open Pit called Oroya Brown Hill.   KCGM said all explosives had been laid in accordance with strict safety procedures and that wind conditions had been monitored to minimise potential impacts to the community.
