Resilience estimation of the mining fleet (Case study: Sungun copper mine)

In recent years, the application of the resilience concept has increased in various domains. Resilience depicts the ability of a system to return to its normal operational status after failure events or disruptions. According to the literature survey, there are various studies, which have been done in the field of engineering and non-engineering systems, and there is no study about applying the resilience concept in the field of the mining industry. In this paper, first, the resilience concept is introduced, and the resilience of the mining fleet of Sungun copper mine is estimated later on. For this aim, performance indicators of the system (i.e., reliability, maintainability, and supportability) are used. The results showed that the resilience of the entire system for one hour of its function is equal to 83.1%, and this value decreases to 37.1% after 10 hours. It means if there is a failure in the system, it will have 83.1% and 37.1% probabilities to be resilient against the failure event after 1 hour and 10 hours of system function.
