Controle de material particulado nos acessos de mina a céu aberto

Abstract

The search for better environmental and working conditions, driving firms to improve standards for particulate control. In this work were discussed studies done about the major pollution sources, as well as current forms of control of air pollution in the accesses of Mines Complex Sossego aimed at analyzing the current methods for removal of particulate material in the accessions of this mine, with emphasis on application of calcium chloride, a product that is being increasingly used due to its high stabilizing potential, acting in the flocculation of dust particles and keeping them online, where it was applied wet for a long period of time. Tests were carried out and bibliographic analysis in that mine field about issues related to air pollution caused by mining: the forms of dust control in mining, occupational diseases caused by exposure of workers to dust emission, the atmospheric monitoring and evaluation of results.
