Open-cast mines are dug on benches, which describe vertical levels of the hole. These benches are usually on four to sixty meter intervals, depending on the size of the machinery that is being used. Many quarries do not use benches, as they are usually shallow. Figure 1. Note the angled and stepped sides of the Sunrise Dam Gold Mine, …

Open-pit mining is a non-tunnel mining process providing direct access to minerals and stones close to the Earth's surface. This method of mining involves the use of explosives to create large, canyon-like holes, which are then refined into workable pits using heavy machinery. The open-pit mining process is often done in a step-like fashion.

Open Cast Mining. 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.
