2. Truck trolley system . The use of truck trolley systems dates to 1882, when Werner von Siemens developed the first electrical driven wagon that followed overhead power lines. This system has been evolving since and has been used in the mining industry since 1967, when it was implemented in the Chino Mine in New Mexico.
To extract minerals from open-pit mines, various tasks are performed such as drilling, blasting, loading and hauling. Of these, the haulage operation is the most expensive, comprising half up to two-thirds of the total operational costs (Chaowasakoo et al., 2017b).Shovel–truck systems are a widely adopted hauling approach, particularly in large …
