SKM undertook conceptual engineering comprising the identification, studies and analysis of the principal alternatives for copper ore extraction and handling, in a new underground mine below the present open pit of the Chuquicamata Mine in northern Chile.
Two main options were studied for ore extraction; these being panel caving and macro blocks: for each option, three extraction panels were identified at different depths. For panel caving at the 1841, 1697 and 1409 m.a.s.l reference levels and for macro blocks at the 1841, 1625 and 1409 m.a.s.l reference levels.
The required underground mine production capacity is 120.000 t/d to meet the demands of the downstream ore processing facilities.
The project battery limits extend from the exploiting ore point to ore dumping for processing through the concentrator plant.
SKM’s main installations/activities included:
- Complete underground mine infrastructure
- Exploitation facilities
- Secondary, intermediate and main ore conveyors
- Underground crushing
