Abstract
The productivity of a mining company depends on many factors, thereby the availability of the industrial equipment of the sectors that constitute it is a predominant factor. It is in this context that the present work was developed, addressing the aspects of operation and maintenance of the sector of a mining unit of a mining company, being this sector one of the main chain of activities of a mining company. A technical analysis of the main problems of maintenance and operation of the sector was made, based on the impacts on the equipment availability and the productivity of the sector. Critical analyzes of failures were carried out, culminating in the emergency corrective maintenance of two fundamental equipment of the process. In the first equipment, the fatigue process of the drum shaft of a belt conveyor was identified and the cause of intervention in the second one was due to a crack in the support frame of an electric motor of operation of a crusher. As a result, the methodological application of flaw analysis was highlighted in the aforementioned two events. The investigative approach of each of the events has allowed to identify the root causes of the failure, thereby providing the starting point for solving the problem for its causes and preventing failure from occurring again, provided that preventative measures are adopted. It was conclusive that the adoption of the suggested measures during critical failure analyses can reduce the frequency of interventions by operation and maintenance crew, providing predictability of the desired availability for the equipment and consequent Company's satisfactory productivity.
