There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8). Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface.
Open pit and open cut mining are the least expensive techniques for the ore extraction. Overburden and stripping ratios are important in determining whether a deposit is to be mined. The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1
