Abstract
Over the past few decades, open cast mining operations have steadily increased their production rate by using large mining equipment like a surface miner, bucket wheel excavator, etc. Among them, the surface miner is one of the most popular equipment in coal mining industries, which is used for cutting, crushing and carrying the coal, limestone and other minerals in a single operation without any need for drilling and blasting. Availability of machine depends upon factors like maintainability of a machine, reliability of components, how effectively maintenance procedure is implemented, types of machine, nature of work performed by a machine, environment condition in which machine performing, operator's capabilities or experience, etc. The analysis is concentrated towards the study of the operational systems of surface miner L&T KSM 303. To know about the performance of machine as well as to improve the performance of machine,breakdown and operational data collection and its analysis is one of most important task which help in assessment of availability,critical components,Mean Time Between Failure(MTBF), Mean Time To Repair (MTTR), etc. of the machine. Generally, To reduce the unplanned breakdown of machine, there is need to increase the reliability of each component by implementing the different research methodology like Failure Mode, Effects and Criticality Analysis (FMECA) and Fault Tree Analysis (FTA)
