Huge trucks, shovels and cranes are employed in surface mining to move large quantities of overburden and ore. Processing plants can utilize large crushers, mills, reactors, roasters and other equipment to consolidate the mineralrich material and extract the desired compounds and metals from the ore.
Job duties in the mining industry usually depend on the particular segment: oil and gas, metal ores, nonmetallic mineral mining (quarrying) and mining support. For example, coal miners can work in deep coal mines or on surface mining areas, where they are responsible for extracting coal, bringing it to the surface and transporting it to the buyers.
Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
