Surface mining; Surface mining is a method of mining that involves removing the soil and the overlying rock on top of the mineral deposit. This method of mining gained popularity since the start of the 20th century, especially in North America where the majority of surface mining occurs. Most forms of surface mining use heavy equipment such as ...
