What are the main methods of mining? American ...

2020-7-20  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. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Commonly used mining techniques to extract coal

As mining of coal depends on the depth and quality of the coal seams, different techniques are used to dig the deposits. Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction.
