Equipment Selection for Surface Mining A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

What is subsurface mining? Study

Answer and Explanation Subsurface mining is when the materials being mined are below the surface of the Earth. This means that the mining must occur below the surface as well, because the resources cannot be accessed from surface level. Subsurface mining is done by building reinforced tunnels down from the surface to the place where the resource is located.
