Abstract: |
The mining complex Chuquicamata, of the National Copper Corporation of Chile (CODELCO), is located in the Atacama Desert, 1, 650 km north of Santiago, and 2, 870 m above sea level. Since the large copper ore reserve that lies below the "Chuquicamata" open pit (Fig. 1) will no longer be economically feasible to mine from the end of this decade, the mine is currently developing the required infrastructure to switch the operation to an underground mine type, where the block caving method with macro-blocks will be used to mine out copper ore. The future mine will count with four production levels, corresponding to one of the largest underground mining operations in the world, with a production rate of about 140, 000 t/d. This article presents design aspects of the permanent underground infra-structure works, which encompass several deep and steep tunnels and vertical shafts for the future mine access and operation. |
