| Sumario: | The operation quality of shovel-truck systems (STSs) at open-pit coal mines in the summer and transitional autumn-spring periods differs markedly. This is due to a decrease in the speed of haul trucks during the transitional season compared to the summer season. This leads to an increase in the travel time of trucks. Shovels and trucks must work longer to ensure the planned volumes of loading and transportation and the required number of hauls. Consequently, the duration of the working shift (or day) increases. This leads to deterioration in the STS performance in the autumn-spring period. A quantitative assessment of changes in the STS operation quality will reveal the directions of its improvement. |
