Plano de drenagem para as frentes de decapeamento com trator de esteiras a Mina de Bauxita de Juruti

Abstract

The Bauxite mine in Juruti, Brazil, is a mining venture that was the beginning of his production recently. Because of this, adjustments in their operating procedures are still occurring, seeking safety, operational efficiency and cost reduction, however, respecting the sustainable vision, which is the culture of this project and urge the local community. Within this context, through field observations it was noted the excess moisture and contamination of the strips of clay minerals, a fact that was reflected throughout the process, causing stoppages in the operation of crushing, generating loss of production. Although empirical, the study used in its development of quality tools that offered a framework for understanding the problem and the solution presented later. Seeking recognition, the origin and resolution of the problem at hand, some tests were performed, including: analysis of the intensity and frequency of the problem, assessing the influence of mining method and rainfall. After completion of these and found the impact of excess moisture and contamination with clay layer of ore, it was decided to include a drainage plan to the procedure of stripping the fronts of mine when used bulldozers, where it was defined after testing in the area, seeking greater efficiency.
