Análise de produtividade na operação de decapeamento de estéril da Mina de Bauxita de Juruti - PA

Abstract

Bauxite is the principal ore used to produce aluminum due to its high content of alumina (AlO2). Due to the characteristics of deposits of bauxite, tabular geometry, near-surface and low thickness of the ore, its extraction is performed using the already established method known as strip mining or mining in strips. In bauxite mining, as in all large mining, the use of equipment is paramount to the success of the project, so having knowledge of the indicators of performance of the equipment involved in the production process leads to good fleet management equipment , culminating in an increase in global mine production. Among the indicators of performance, production or productivity of the equipment can be deployed considering the endless search for "optimization" of this indicator. So in Juruti Bauxite Mine, owned by the company of American Aluminium Company - Alcoa, a study of productivity of crawler tractors involved in the operation of stripping the layer of sterile, targeting a critical analysis of this important indicator.
