surface mining, method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.
What are the three types of mining?
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.

What are the different types of strip mining?
Two types of strip mining exist, depending on the amount of ore under the surface, and the surrounding terrain. They are: Area Stripping extracts ore over a large, flat terrain in long strips. The overburden of rocks and soil is dropped in the previous strip so that long gaps aren’t left in the earth after mining is complete.
