Lesson 7.3: Mechanical Surface Mining Methods - Open

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.
