Underground Mining vs. Surface Mining, What Are Their ...

The surface mining process is very complicated. Surface mining(ground mining) is suitable for large, low-grade ore deposits. These ore deposits occur below a thin layer of rock or alluvial deposits found in sand and riverbeds. In particular, using this mining method, miners retrieve sand, gravel, stones, coal, iron, and other metals.
