Melhorias ergonômicas após modificações da estrutura das peneiras de beneficiamento de minério de uma mineradora: um estudo dos possíveis reflexos sobre a organização do trabalho dos mecânicos soldadores

Abstract

The repetitive strain injuries and osteoarticular disorders related to work have been the subject of several studies due to increasing incidence among workers of almost all economic activities worldwide. This study presents a methodology to improve the working comfort in the sieve ore beneficiation, one of the workplaces of a mechanical welders iron mining company in the metropolitan region of Belo Horizonte. This study uses ergonomic concepts, considering them the most likely cause of these disorders, rising absenteeism in the industry. Changes were proposed in the sieves in order to reduce absenteeism occurred and suggest changes in work organization of mechanical welders. The proposals were based on systematic observation of the functioning of the screens in the analysis of physical space, the use and characterization of the same and the work routines. With the implementation of the new layout is expected to increase safety at work of mechanics, welders, reducing absenteeism and improving the performance of tasks, thereby increasing productivity. It also recommended a reassessment of the systematic processes to achieve an even more close to ideal for human organisms that there spend much of their day.
