This method of mining is carried out where useful minerals or rocks are found near the surface. When the surface material covering the valuable material is relatively thin this kind of mining is more suitable. Open cast mines are dug on benches which are usually four to sixty meter intervals and the machinery used depends on the size of the area.

Open cast mining is usually associated with coal or other tabular deposits that are more or less flat-lying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut. Therefore, reclamation occurs
