Reliability analysis of mining equipment has become essential for mining organizations for enhancing the availability of the machine and for achieving the established production targets. A large variety of equipments are involved in open cast mining viz., bulldozer, shovels, dumpers (tippers), draglines etc. Any breakdown in these equipments may result in unavailability of machine and loss of production. In order to avoid such instances, analyzing and enhancing the reliability of these equipment is necessary. Also, before conducting any reliability analysis, it is important to know and detect the trend in failure data of a system, which gives an idea for further analysis of the data. In this paper, statistical tests are used to detect the trends in the failure events of dumpers and also the underlying hypothesis have been tested using the same. For this, Laplace test and Crow/AMSAA was adopted to detect the possible trend in the failure data of dumpers used in open cast mining and conclusions were made based on the hypothesis obtained.
