Mining and milling. Markus H.A. Piro, Ksenia Lipkina, in Advances in Nuclear Fuel Chemistry, 2020 8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground …
In an open pit mine, heavy trucks move ore, broken rock with enough metal concentration to be profitable, and waste rocks between mining faces within the pit, commonly …

Mining trucks, also referred to as haul trucks or road trucks, are used to haul (transport) the ore or waste material from the loader to the dumpsite. In most cases, these vary …
We propose, implement, and test two approaches for dispatching trucks in an open-pit mining operation. The first approach relies on a nonlinear optimization model that incorporates queueing effects to set target average flow rates between mine locations. The second approach is based on a time-discretized mixed integer programming (MIP) …
