Abstract: The industry-specific methods for assessing the performance indicators of mechanized combine systems of potash mines are analyzed. Correct assessment of the operational productivity of mechanized combine systems, taking into account the influencing factors of mining and geological conditions, determines an increase in the stability of technological processes in the extraction chamber and an increase in the efficiency of using the mining and transport equipment of potash mines. The currently used methods for determining the operational performance of combine systems of potash mines are characterized by considerable complexity. A method of assessing the performance of the combine system based on the definition of work expressed in conventional units is proposed. The use of the proposed method allows a significant reduction in the amount and time required to perform assessment, while the weighted average performance of the combine system can be determined at any part of the extraction chamber. The proposed method can be adapted and used in mines with different mining and geological conditions of work.
