These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.

It is used as an alternative for the conventional transportation system (Truck-Shovel system) in surface mining operations (Radlowski, 1988). It generally resolves many deficits of the Truck-Shovel system e.g. reducing operating costs (Terezopoulos, 1998) mainly because of the reduction of the labor force and fuel consumption (Dean et al., 2015).
