Amankwah, H. (2011). Mathematical Optimization Models and Methods for Open-Pit Mining. Doctoral dissertation. ISBN 978-91-7393-073-4. ISSN 0345-7524. Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them, and in this process a deeper and deeper pit is formed until the mining operation ends. Mining is… (More)

We consider the problem of finding an optimal mining sequence for an open pit during a number of time periods subject to only spatial and temporal precedence constraints. This problem is of interest because such constraints are generic to any open-pit scheduling problem and, in particular, because it arises as a Lagrangean relaxation of an open-pit… (More)
