Open-pit mining operations are long-term investments, and therefore, are subject to possible unexpected changes during the mine exploitation stage.

  • Open Pit Mining an overview ScienceDirect Topics

    An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then 17* Open Pit Optimization Strategies for Improving,2009-9-17 · ABSTRACT: The open pit design and scheduling problem is a large-scale optimization problem that has attracted considerable attention during the last 40 years The development of the "know-how" to improve economics of open pit mining projects through the use of mathematical optimization techniques goes back to early 1960's. Unfortunately, up until recently, many of these "optimizing algorithms" could not be implemented due to the limited capacity of the computer hardware used in many mining operations. During the last 10 years, advancements in the computer hardware technology along with developments in software technology allowed open pit mines
