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

In recent years, using of the resilience concept has been increased in order to evaluate the response of systems against the failures. Resilience depicts the system ability to return to its normal operational status after failure accruing. 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 resilience concept in the field of mining industry. In this paper, at first, resilience concept has been introduced and then the resilience of the mining fleet of Sungun copper mine has been estimated. Systems performance indicators include reliability; maintainability and supportability have been used in order to resilience estimation. The results showed that the resilience of the entire system for one hour of its function is equal to ۸۳.۱% and this value decreases to ۳۷.۱% after ۱۰ hours. This means if there is a failure in the system; it will have ۸۳.۱% and ۳۷.۱% probabilities to be resilience against the failure event after ۱ hour and ۱۰ hours of system function.
