Abstract: A material management system and method manages and tracks the progress of excavated material transferred through an excavation site by a conveyer system operating in cooperation with an in-pit crusher and conveyer (IPCC). The material management system distinguishes the material dispensed into the IPCC into identified material batches. To track the identified material batches, the material management system records data regarding the conveyer speed and the conveyer distance associated with the IPCC, as well as possible other data regarding the identified material batches. The material management system processes this to track the indentified material batches along the conveyer route.
