Abstract: To examine the influence of endurance mileage of electric mucking vehicle on work efficiency and cost in long-distance tunnel construction, the endurance mileage, loading capacity, and construction demand of the electric mucking vehicle are analyzed to constructed a configuration model of the electric mucking vehicle in the long-distance tunnel, providing guidance for vehicle configuration and scheduling. Considering the basic assumptions such as muck loading time, muck unloading time, and average speed, the constraints such as mucking quantity constraint, vehicle number constraint, continuity constraint, and driving mileage constraint are constructed. Based on a case analysis, the configuration requirements of electric mucking vehicle under different endurance mileage of main tunnel and parallel guide tunnel are calculated, and the configuration differences caused by the change of endurance mileage in different seasons are analyzed. The results show that the endurance mileage of the electric mucking vehicle exhibit a significant impact on the vehicle configuration and operation efficiency. Increasing the loading capacity of a vehicle is not the best solution to reduce the vehicle demand, and many factors such as driving distance and endurance mileage should be considered comprehensively.

Key words: long-distance tunnel, endurance mileage, electric mucking vehicle; configuration model
