Design of Costs-Based Metrics for Enhancing the Economics of the Mining Truck Fleet

摘要

Modern mining activities are very intense in capital use, highly mechanized and as a consequence, present high operational costs. In this sense the appeal for managing operational variables adequately is very attractive since these have a huge impact in the overall costs. Reportedly, one of the most expensive mining activities is the transportation of in situ material to its destination. In this regard, the correct management of the important operational variables coupled with the experience gathered in mining operations, allowed the development of a computer system aimed at helping to achieve these management objectives. This paper describes the relation between measurable variables and economic parameters obtained in one important large scale Brazilian mine and how they interact and relate to each other in order to facilitate the decision making process.
