Mar 25, 2021Surface Mining. Surface mining includes numerous techniques and is the most common method for non-fuel minerals, producing 97% of the amount mined. Miners choose surface extraction for minerals located close to the surface. There are three main ways to mine on the surface. These methods include quarrying, open-pit mining, and strip mining.
