Open-Pit Mine Production Planning and Scheduling: A …
Abstract. Mining is a complex, expensive, yet lucrative business. Today's open-pit mines are huge projects in Australia. To keep the projects profitable, planners and schedulers are under constant pressure to make mine plans that are as accurate as possible and optimize production at all stages, from mine to market.

Open Pit Mining
Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.

Surface mining planning and design of open pit mining
4. Although the basic concept of an open pit is quite simple, the planning required to develop a large deposit for surface mining is a very complex and costly undertaking. At one mine, it may be desirable to plan for blending variations in the ore so as to maintain, as nearly as possible, a uniform feed to the mill. At another operation it …
