Mining complexes contain multiple sequential activities that are strongly interrelated. Extracting the material from different sources may be seen as the fir...

et

Scheduling production in open-pit mines is characterized by uncertainty about the metal content of the orebody (the reserve) and leads to a complex large-sca...

Subsurface flow and solute transport simulations are performed using different scenarios of permeability fields generated from the sequential Gaussian simula...

et

The classical maximum closure problem is of particular importance to the mining industry because it is the underlying formulation related to mine design and ...
