Nov 29, 2013· AbstractOver the past century, open pit mines have steadily increased their production rate Larger equipment and new technologies make it possible to mine larger batches of materials in a shorter time Low commodity prices have forced companies to decrease their unit cost, by using new technologies and improving productivity In the late 20th century, with companies facing low ,...
AbstractEquipment selection is one of the most important factors in open pit design and production planning Equipment selection also affects economic considerations in open-pit design as a function of plan location and depth Furthermore, equipment selection is a complex multiperson, multi-criteria decision problem The group decision-making process can be improved by a systematic and logical ....
Methods for estimating productivity and costs, and dependent equipment selection process, have needed to be increasingly reliable Estimated productivity and costs must be as accurate as possible in reflecting actual productivity and costs experienced by mining operations to accommodate the long-term trend for diminishing commodity prices, For loading and hauling equipment operating in open ....
