The winner in Michilla

2006 Jun 30

Cable bolting and grouting operations have been greatly speeded up at the Michilla Copper Mine in Chile with the introduction of a Cabletec rock bolter.

The first Cabletec rock bolter in South America is successfully operating in Antofagasta Minerals? Michilla copper mine in Chile, some 750 km north of Santiago. The main mining method here is cut-and-fill using a drift and pillar layout and mining progresses upwards.

Michilla is operating at depths of below 600 m and produced 46,000 tonnes of fine copper in 2005. Resources are expected to last until 2012 after which production will shift from underground to surface operations.


Epiroc operated under the trademark “Atlas Copco” prior to January 1, 2018.
