This paper attempts to apply the resilience concept to the mining sector, especially to mining machinery and productionsystems. The quantitative analysis method using the linear recovery function has been applied. As the core part of theproposed method, it is assumed that in the mining machinery fleet, the performance function falls to a “zero” value immediatelyafter the occurrence of a failure. Therefore, the resilience calculation process runs through the concept of timeto repair and machine maintainability. As a case study for the proposed concept, the operation and failure data of thedrum shearer machine in Parvadeh longwall mine in Iran is applied. The data pertains to a coal cutting operation in awhole longwall panel over the period of two years. In total, the calculations encompass over 2600 hours of actual operationand 171.8 hours of repair time, which reveals that the studied shearer has a resilience of 96.7 percent. Along with thecase study results, it is confirmed by this paper that resilience as a developing concept could be adequately applied to coalmining systems as a support measure for production assurance and reliability.
