Metodologia para Análise da Eficiência de Frotas de Carregamento e Transporte em Mineração utilizando o Software Microsoft Excel

Abstract

The correct measure and operational efficiency of the loading and haulage fleets are Essentials for the success of the mining industry. This paper’s purpose is to make a bibliography review which demonstrates, in a clear and objective way, the main concepts to measure these fleets and the development of a simple method to analyze the operational efficiency of these fleets at the mine daily work. For the bibliography review about the equipment measurement several books from highly-respected authors have been used, such as Howard Hartman, Bruce Kennedy and Guilherme Catalani. Regarding the analysis of the equipment efficiency, the data used to illustrate the methodology is from the Sossego Mine in January 2009. The analysis uses as a tool the Microsoft Office Excel and it’s data analysis software. The options used will be the histogram and the statistic analysis of the data provided. . Based on the interpretation on the results obtained, it is possible to verify with a good certainty if the loading is being done homogeneously and if the haulage time at each route is suitable with the truck used.
