Determination of the identicalness of the trucks working in open pit coal mine and using in availability analysis

Abstract

The equipment of open pit coal mines are generally categorized as loading equipment and hauling equipment. Trucks are usually used as hauling equipment in open pit coal mines. Thus, determining the identicalness of the same model trucks working in open pit coal mine has a key role for the surface mining systems. In this study, whether a group of three trucks picked randomly from the same model trucks working in open pit coal mine was identical or not was examined through a non-parametric statistical test for two independent samples. Then, in order to determine whether the trucks proven to be identical at the end of this test displayed the same performances or not, an availability analysis for the identical trucks was carried out. As a result of the availability analysis, it was observed that the randomly picked trucks displayed the same performances. It was also determined that non-parametric statistical test for two independent samples could be employed together with availability analysis.
