| description | Achieving the high production and productivity targ et is one of the biggest challenges for any mineral industry, in order to remain competitive in the global market. The maximum production of mining
equipment is possible by ensuring maximum reliability and maintainability, which results in increasing the availability of equipment. The present paper is an endeavor to compute inherent availability
of dragline machine and critically analyze reliability and maintainability of dragline’s subsystems in one of the major open cast coal mines in India. The inherent availability of the studied
dragline was 0.8402 (low). The Reliability, Availablity, and Maintainability (RAM)study has further highlighted the fact that the structural part with the maximum Mean Time To Repair (MTTR=8
8 h) and bucket subsystem with the minimum Mean Time To Failure (MTTF=54 h) are the major contributors to low inherent availability. |
