• Equipment selection for surface mining: a review

    Abstract. One of the challenging problems for surface mining operation optimization is choosing the optimal truck and loader fleet. We refer to this problem as the equipment selection problem (ESP). In this paper, we describe the ESP in the context of surface mining .

  • Equipment Selection for Surface Mining: A Review

    A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.

    In surface mining, equipment operating costs are generally more than half of total operating costs. To control costs, therefore, optimal selection of equipment is vital. Main considerations in primary equipment selection are the geology of the deposit, production requirement, project life, capital availability, operating cost, geotechnical parameters and resources recovery.
