Abstract: Stripping and mining operations in open-pit mines are performed mainly by powerful shovel-truck systems (STSs). One of the main problems of the STSs is the rather low level of their operating quality, mainly due to the imbalance of the influence of various factors on the efficiency of joint work of shovels and haul trucks as parts of the STS. A functional criterion for assessing the quality of the STS operation at open-pit mines is formulated, derived and analyzed in this article. The rationale, the general principles of the functional criterion formation, its general form for mixed (heterogeneous) truck and shovel fleets, typical of modern mining STSs, are presented. For this purpose, modern methods of data collection and processing, mathematical modeling, analysis and synthesis are used. The ability to assess the quality of the STS operation is of great importance for identifying the main directions of improving their operational performance and operating quality, optimizing the main performance indicators by the quality criterion, and, as a result, for possible saving of material and technical resources for open-pit mining. Improving the quality of the STS operation will also improve the mining safety and reduce harmful emissions into the atmosphere – by means of possible reduction in the number of operating trucks.
