Abstract: The urgency of the discussed issue. Loading and transport operations in open-pit mines are performed mainly by heavy shovel-truck systems (STS). One of the main problems of the STS is a rather low level of its operation quality, an objective assessment of which is an important step in identifying the causes of poor quality and effective ways to improve it. The purpose of assessing the STS operation quality is defined as a functional criterion. The next important step of the assessment is to choose the nomenclature of indicators which characterize the STS operation quality to the greatest effect.
The main aim of the study. Justification of the nomenclature of STS performance indicators for further quality assessment and for development of a methodology for optimizing STS indicators.
The methods used in the study. Modern methods of data collection and processing, analysis and synthesis were used.
The results. The STS operation quality can be assessed by seven indicators, which are divided into four groups: indicators of the composition, structure and matching of loading and transport equipment fleets; indicators of the fleet performance (potential or actual); indicators of the value and structure of downtimes; indicators of the fleet productive use during a shift. The STS operation quality assessment by these indicators makes it possible to identify the main directions of increasing its operational performance.
