Since 1980, the Parabola copper mine has taken a series of changes to try to offset the impact of falling product prices and rising production costs. These changes and improvements include the rationalization of major equipment, the promotion of wireline-assisted vehicle transportation, and the application of sophisticated automotive computer control systems. Open-pit mine design enhancements, improvement of perforating work, use of emulsion explosives, and use of crusher and conveyor systems in stope. This article describes the various changes in the Palabola mine and the impact of these changes on production and its role in reducing costs and increasing labor productivity.
