Open pit block scheduling with exposed ore reserve

iCalendar

Jorge Amaya Universidad de Chile, Chili

Operational mine plans are usually produced on a yearly basis and further scheduling is attempted to provide monthly, weekly and daily schedules. A portion of the ore reserve is said to be exposed if it is readily available for extraction at the start of the period. We propose an integer programming (IP) model to generate pit designs under exposed ore reserve requirements, as an extension of the classical optimization models for mine planning. For this purpose, we introduce a set of new binary variables, representing which blocks can be declared as exposed ore reserve, in addition to the extraction and processing decisions.
