The article examines some problems, connected with open pit excavating machine operating time. The methods
of calculating annual capacity are analyzed. Some contradictions that arise when calculating operating time of a mining
machine are revealed; they are described by various sources. The question is put about the repair cycle time tracking
purposefulness when determining annual capacity of an excavating machine. The article reveals the analysis results for
various periodicity types in between capital ones depending on the elaboration of in-service hours by an excavating
machine. Methodological recommendations to calculate operating days of an excavating machine in a year are revealed
with the account of repair cycle and specified operation ratio during the shift.
Key words: rock mass recovery; power shovel; shoveling machine; mining machine maintenance; mining equipment
