Formatted abstract
Maintenance related costs account for approximately 30-50% of the direct mining costs; therefore it is the largest controllable expense in the mining industry (Campbell 1995). In response to the impact of maintenance, the strategies applied to mine maintenance have progressed through the years towards a more reliability centred focus.

The thesis topic was the Failure Modes, Effects and Criticality Analysis of Mobile Mining Equipment within a Reliability Centred Maintenance Program. More specifically the analysis focused on the rear dump truck fleet at Tarong Coal. Reliability Centred Maintenance or RCM is “a process used to determine the maintenance requirements of any physical asset in its operating context” (Moubray 1997). A Failure Modes, Effects and Criticality Analysis or FMECA is a qualitative tool used in the process to achieve an RCM program; it identifies all possible modes of failure for a piece of equipment. It then qualitatively analyses the impact and criticality of each failure mode.

Tarong Coal’s major reason for initiating the thesis was to improve the efficiency of planned maintenance, therefore increasing the availability and reducing breakdowns of critical equipment. To accomplish these long-term goals, the RCM process needed to be optimised for mobile equipment at Tarong Coal. By completing the analysis required, progress was made towards a more reliability centred strategy.

A FMECA was required on at least the critical systems of the truck; including the engine, air conditioner, brakes, steering and hoist systems. To increase the value of the thesis for Tarong Coal, the FMECA methodology was critically reviewed and optimised. As a result of the FMECA, a spreadsheet needed to be created to effectively communicate the data. Finally the major objective for Tarong Coal was to increase the efficiency of the planned maintenance on the truck fleet.

While completing the FMECA, the basis of the approach centred on Moubray’s (1997) seven questions for RCM. Testing different methods and reviewing their success formulated an ideal action plan. Various review sessions assisted in finalising the format and content of the spreadsheet. Using the knowledge gained during the FMECA allowed for an improvement to the planned maintenance sheets.
