1. Large Mining Trucks. To move materials around a mine site, workers need heavyduty trucks. Also known as offhighway trucks, large mining trucks include both powerful mechanical models and environmentally friendly electric drive models.. Unlike conventional trucks, these mining vehicles have extralarge tires to support the heavy loads over uneven terrain commonly found around surface mines.

The open pit mining load and haul system has been a mainstay of the mining industry for many years. While machines have increased in size and scale and automation has become an important development, there have been few innovations to the actual load and haul process itself in recent times. This research highlights some of the potential productivity and safety benefits that the incorporation ...

Approximately, 40% of the total energy used in surface mines is related to diesel consumption. Truck haulage is responsible for a majority of this. This chapter introduces the principal equipment used to load and haul materials in mines, namely trucks, electric rope shovels, hydraulic excavators and crushing and conveying systems.
