Mining Trucks, Loaders & Haulage Equipment
Mining trucks, loaders and haulage equipment for the mining industry. Loading and haulage are fundamental to both surface and underground mining operations. Miners use mining trucks, loaders and haulage carriers to not only transport the run-of-mine (ROM) ore to the processing area but also remove overburden and waste rocks from the mine site.
Surface Mining Transportation Systems
Surface mining process somewhat varies depending on how the target mineral deposit is situated, e.g. horizontal, inclined, or interbedded, but commonly includes the following four steps: 1) top soil removal, 2) overburden removal, 3) extraction of ore, and 4) reclamation of mined-out site. Each step is further detailed in Table 1.
