A importância das operações de infraestrutura de mina - um estudo sobre as atividades realizadas na lavra de bauxita pela Mineração Paragominas S/A

Abstract

The extraction of a mineral resource involves a number of parameters that must be perfectly synchronized to meet the needs of a mine. For the effective development of the mining, a series of actions related to infrastructure, such as clearing, construction and maintenance of ramps and accesses, mine signaling and drainage plans, must be performed in order to provide the necessary support to the mining operations. Without a proper design or with a lack of such infrastructure parameters, several problems may happen in the mining inherent activities, impairing them in terms of pace of production. Despite the great importance associated to the mine infrastructure, there are few theoretical information available that portray the theme and show how these activities are peculiar to the process of developing the improvements of the mine strategic plan. Thus, the present work aims to present the mine infrastructure operations and demonstrate their importance to the success of the mining unit operations and other activities involved in the mineral industry. Due to the scarce theoretical subsidy that portrays the theme, it will be presented here the operating parameters used in the mine infrastructure in the bauxite mine in Paragominas, Pará, by Mineração Paragominas S.A., in order to ensure the subject didactics. From the information gathered can reach a critical and informational analysis of the various parameters that may be associated with an activity of mining, with regard to the infrastructure of the mine and also demonstrate what the major issues associated with the same parameters and which still need more attention.
