cut, the reclaimer moves along the whole length of the stockpile with a fixed boom position. Then the boom is adjusted for the next cut, the reclaimer turns around and moves along the stockpile in the opposite direction as indicated in Figure \[fig:reclaim\]. The reclaiming process is fully automated and a typical stockpile is reclaimed in three benches with approximately 55 cuts. In our simplified model we assume that a stockpile is reclaimed while a reclaimer moves along it exactly once.
