Patent Images
1. A mine power management system comprising:
- a first power line provided at an ascent and configured to exchange electric power with an ascending vehicle traveling on the ascent;
a second power line provided at a descent and configured to exchange electric power with a descending vehicle traveling on the descent;
a power supply and storage apparatus configured to exchange electric power at least between the first power line and the second power line; and
an electric power control unit configured to control electric power allocation at least among a machine, the ascending vehicle, and the descending vehicle so that a total electric power consumed by the machine, the ascending vehicle, and the descending vehicle that exchange electric power with the power supply and storage apparatus is equal to or less than a total electric power generated by the machine, the ascending vehicle, and the descending vehicle.

19. A mine power management system comprising:
-
a first power line provided at an ascent and configured to exchange electric power with an ascending vehicle traveling on the ascent; a second power line provided at a descent and configured to exchange electric power with a descending vehicle traveling on the descent; and a power supply and storage apparatus configured to exchange electric power at least between the first power line and the second power line, wherein a sum total of heights of a plurality of the ascents where the first power line is provided and a sum total of heights of a plurality of the descents where the second power line is provided are within ±
10% with respect to an average value of the sum totals.
