Estudos de otimização na utilização dos tratores de esteira caterpillar D11 na Mina do Sossego

Abstract

This work deals a study developed in the area of infrastructure in the Sossego Mine located in the municipality of Canaã dos Carajás. It is a work based on the optimization of the fleet of track-type tractors of Caterpillar D11, who were suspected of high maintenance costs, mainly due to accelerated wear of undercarriage, and high fuel consumption. There were also problems in the amount of unproductive hours causing operational delays due to their own locomotion, which is the locomotion of D11 tractor from one point to another within the mine in order to move the equipment for distribution in areas of work different. The completion of this work tries to find the reasons causing these problems, and concomitantly proposing appropriate solutions to minimize them. The results of this research have opened a range of information sufficient to offset some suspicions and focus on possible solutions to enable the possibility of investment in the purchase of new equipment to assist the operations of the infrastructure of Sossego Mine.
