ABSTRACT

Coal mining trucks is failure in accordance with many reasons. As, the size and complexity of trucks continue to increase, the equipment failures become ever more
important. In this study, maintenance and repair durations for coal mining trucks are
examined by using factor analysis and The Kolmogorov-Smirnov test for two independent samples techniques. These techniques are applied to dataset obtained by six
different trucks working in coal mining. As the result of these methods, it was determined that there are two different groups are composed according to maintenance
and repair durations. The study also shows that the factor analysis and The Kolmogorov-Smirnov test for two independent samples are very useful for examining maintenance and repair durations.
