Mining is one of the most vital components of modern society due to the use of mined minerals in almost every consumer product. Additionally, 50% of the nation's energy comes from coal or nuclear power that uses uranium. To support this need for modern equipment, mines are found in all 50 states, including our home state of Nevada.

Strip Mining. In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock, i.e., the 'overburden' is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out ...
