Research on Determination of Performance Evaluation of Mobile Manufacturing Units (MMUs) for Surface Mines – An OEE Approach

For the measurement of overall equipment effectiveness, it is necessary to determine the magnitude

of the types of production losses in order to plan activities and allocate resources effectively. The

application of Overall Equipment Effectiveness (OEE) in Mobile Manufacturing Units for mining

operations have not been duly adopted. There is the need to do the assessment of maintenance

performance indices like availability and utilisation for improvement in productivity. This paper seeks

to determine the maintenance performance indices like availability and utilisation of Mobile

Manufacturing Units (MMUs) of African Explosives Limited (AEL) operations at Goldfields Ghana

Limited, Damang. It was determined that the availability and utilisation were 93.55% and 30.61%

respectively. The results obtained can contribute to the knowledge about the solution for improvement

in scheduling of mine operations and the efficient monitoring of controllable factors that enhance

maximum availability and utilisation of MMUs.
