Lesson 7.3: Mechanical Surface Mining Methods

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.

Open-Cast Mining: Profit at the Expense of Our Environment

Open-cast mining, or open-pit, open-cut, or surface mining, is a method of extracting minerals, rocks, or other resources from the ground when the deposits are relatively close to the Earth's surface. It is the most commonly applied mining method worldwide. It works by creating a vast, open pit instead of tunneling underground.

Surface Mining Techniques used in the Oil Sands

Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
