Fig. 1, above shows an illustration of a Open Pit Surface Mine. The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life."

In open pit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. .. Improved blasting methods for more precise rock movement and better control of the fragment sizes would reduce the cost of overbreak removal, as well as the cost of downstream processing.
