Assessment of the shovel-truck system operation quality at open-pit mines in Kuzbass

Abstract

Assessment of the shovel-truck system (STS) operation quality is based on the well-known method of non-expert assessment of the quality of mining machines. The methodology is based on the fundamental principles of qualimetry and allows making the assessment of functionally homogeneous machines of different sizes, types and designs based on the functional criterion of the machine, which determines its main purpose. In this work, the quality assessment is made not for a single machine, but for a set of machines, taking into account their interaction. Assessment of the STS operation quality allows us to create a basis for the selection of priority areas for its improvement. The work uses methods of mathematical modeling, data collection and processing, statistics, analysis and synthesis. A comprehensive quality assessment makes it possible to predict the level and select priority areas for improving existing STSs or STSs being projected.
