1. The impact of payload truck factor use in mine performance reports for an open pit copper mine in Brazil
Abstract This article aims to evaluate the use of a truck factor for off-highway trucks in open pit mine operations, thus reducing error on material movement and mine production data entry. This method is current for a copper mine located in South East Pará, Brazil. With a dispatch system, the truck factor is calculated using three data inputs called measur

2. THE BRAZILIAN EXPERIENCE WITH ETHANOL FUEL: ASPECTS OF PRODUCTION, USE, QUALITY AND DISTRIBUTION LOGISTICS
Abstract The reduction in the availability of fossil fuel increased the search for alternative fuel sources (for example, ethanol). In the Brazilian market, light duty vehicles can be fueled with gasohol (18 up to 27.5 %v/v of anhydrous ethanol in gasoline) and/or hydrous ethanol. To minimize the risk of water-induced phase separation of gasoline-ethanol ble

4. Estimativa da emissão de poluentes pelo setor de transporte e análise das ocorrências de doenças respiratórias na área de proteção ambiental do Sistema Cantareira / Estimation of pollutant emissions by sector and transport analysis of respiratory diseases in the area of environmental protection System Cantareira
The global energy matrix is mainly composed by fossil fuels which when burned release air pollutants that affect the environment and human health. In this sense, monitoring health problems related to air pollution is important because it reinforces the need for change in national and international energy policies. This thesis presents a discussion on air pol

6. Viabilização técnica e econômica da lavra contínua de minério de ferro com o uso de sistema de britagem móvel in pit auto propelido
The conventional mining methods employed in most iron ore mines around the world are based in truck haulage. Starting in 1977, Samarco S/A has successfully introduced an innovative mining method in its iron ore mine located in Mariana, MG, Brazil. Samarcos mining method, known as belt conveyor-based mining, has replaced haul trucks for belt conveyors on the
