For the open pit slope, we created a 3D slope case using the composite topographic surface, and the composite failure surface as discussed in section 4. The model created was discretised into columns, with the columns taking part in the slope failure shown in a darker shade (Figure 14).
We consider the short-term production scheduling problem for a network of multiple open-pit mines and ports. Ore produced at each mine is transported by rail to a set of ports and blended into signature products for shipping. Consistency in the grade and quality of production over time is critical for customer satisfaction, whereas the maximal ...

In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.
