Estudo do dimensionamento de equipamentos de carregamento e transporte utilizados na mineração a céu aberto (município de Canaã dos Carajás - PA)

Abstract

The activies of mining are indispensable to supply essentials materials to the industry to make many products, apart from possibility to make new technologies applied in several science’s field. The ore’s extractions of a sediment depend’s on geologic and economic factors that when they show viable, use a set of operations, to a designated surface. To development of a method in order to select the mine’s equipment. The selection of equipments of excavations loading and transporte are defined from the surface method adopted, this could be from surface mine if the the phisycal and geological conditions allow the extraction ore from the surface. The objective is the completely use from the minerals resources the way economic e safe with minimal attack on the environment. In this project, will be analyzed (the local parameters like load factor, blister, density, damp and parameter of equipment like loading factor and efficiency that will be used in study of a methodology to the selection from equipment of excavation/loading and and transport which are the main ways used on the extraction from the mineral goods.
