Open cast mining. Open cast mining is also known as strip mining and is used for bedded deposits, and most commonly for coal. Although it is similar to open pit mining, the distinguishing characteristic is that the overburden is not hauled away to waste dumps; but rather, it is immediately cast directly into the adjacent mined-out cut.

5.1 Open Cast Mining Surface or open cast mining is used for large, near surface deposits. Rock is drilled, blasted, loaded into dumpers and hauled to a place where it is crushed and ground to a uniform size for further processing. Open cast mining needs the removal and disposal of top soil and underlying rock known as overburden.
