n.a.

Period of Activity:

2010 - 2010

The Chuquicamata mine is the world largest open pit copper mine (4.3km-long, 3km wide and 800m deep). It is located 1,650km north of Santiago, Chile. The mine, popularly known as Chuqui, has been operating since 1910. Despite being operational for over 100 years. In 2011, Chuquicamata produced 443.000 metric tons of copper.

— Project Description:

The project involves transforming the world's largest open pit in to a modern and efficient, giant underground operation to exploit some of the resources that remain under the current site. The project involves the extraction through macro blocks with the extraction process "block caving" in an underground mine comprising four levels of production, the main access tunnel of 7.5 kilometers corresponding to the first shot July 6, 2012); five ramps clean air jet, and two exhaust air shafts, among many other works that involve construction, horizontal and vertical developments totaling 121 kilometers.

— Description of Services:
