In modern mining activities, mine productivity highly relies on the availability of high capacity machines. Reliability assessment of these machines has significant impact on understanding the failure behaviors, thus determining maintenance policies accordingly. Reliability analysis of complex systems, such as mining machinery, requires knowledge about failure behavior of their components for more accurate results. In order to combine the failure information of system components to analyze system reliability, there are various methods that can be utilized. Reliability block diagrams (RBD) and fault tree analysis (FTA) are two of the commonly used graphical methods in system reliability analysis. In this paper, general information on RBD and FTA is presented and reliability analysis of a sample system is conducted, utilizing both methods.
