| dc.description.abstracten | Open-pit deposits are often characterized by a stack of layers of different geological nature. Some layers are worthless while the ore of the others is of a varying economic value depending on grade. To reach a layer, it is necessary to have first removed the upper layers above the extraction zone. This action results in uncovering the layer in this particular place and in facilitating access to the layers below. This process involves a series of 2 to 7 operations; each one is performed by a machine, some of which are able to perform up to 3 different operations. Ensuring the consistency of mining extraction scheduling over a few months, in order to meet known or forecast demand, is a challenging task. A mining extraction model based on mathematical programming has been proposed but it is hardly usable due to its size. A Discrete Events Simulator modelling is currently being tested to measure the impact of dynamic rules used to allocate the machines and select the target mining areas | en |
