ABSTRACT In-Pit Crushing and Conveying (IPCC) systems are receiving more attention today due to current characteristics of open-pit mining operations and what is expected to occur in the future. Today, it has become more necessary than ever to reduce the cost of truck haulage, which accounts for roughly half the operating costs of mining operation.
