10 Different Types of Mining Operations and Mines

There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons. This type of mining produces fewer complications regarding water and electricity
