The cost structure for the maintenance and repair contract is based on an equipment availability of ninety percent and is guaranteed by the service provider. It was proved that the actual utilization percentage achieved by the equipment is significantly lower than the provided availability percentage of the equipment. The main data collection method used was observing the maintance and repair activities pertaining to the mining earth moving equipment and the phenomena being researched. Participant observation took place in a workshop setting. The method of exploratory data analysis in analysing the quantitative data was applied . In this way the data are described and summarised and then presented in tables, charts, graphs and other diagrammatic forms.
