Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods …
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.
An Introduction To Surface Mining. Open-pit mining, or open-cast mining, is the most common type of surface mining. Open-pit mines are holes in the ground on a giant scale, which increase in size by blasting and drilling rock apart.
These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.
Surface mining techniques are generally cheaper than subsurface mining techniques. The closer a deposit is to the surface the cheaper it will be to extract. The ideal situation is a deposit close enough to the surface to that it can be removed by the open-pit method.
