Gestão econômica de equipamentos móveis de mineração

Abstract

In the mining sector, the knowledge of the behavior of equipment maintenance costs during their life cycles becomes very important due to the costs involved in the operability and availability of the equipment. Thus, despite of the high resources required for the acquisition of a given physical asset, the purchase should not be decided only based on the initial cost, but rather by the life cycle cost of the equipment in which all expenses incurred throughout his life. This study addresses the application of a methodology for the economic management of assets in the maintenance of mobile mining equipment, which uses mathematical models based on economical engineering and data previously searched with the objective of finding the ideal economic life of a given equipment in conditions and to perform the economic comparison between models that supports the asset selection and acquisition decision. With the economic life modeling elaborated in the present study it is possible to determine the period in which the equipment can be used more efficiently and with lower incorporated life cycle costs, once an economic maintenance management is applied. In this way, it is possible to carry out simulations which allows the improvement of technical and financial indicators considering one or more equipment of companies in the mineral sector.
