The shovels at the loading face are very often electric and have been in a number of mines since the 70s at least - they move from face to face once or twice a day on caterpiller tracks and drag fat cables behind that get protected with "drive over" plates for light vehicles. It's possible that trucks being loaded and trucks queuing to be loaded could upload their excess into the mine grid and then roll down the hill fully loaded with a 100 tonne of ore and a near empty battery. |
