Also called open pit mining, surface mining is removing minerals in formations that are at or near the surface.

Surface mining Surface comprises 90 of the world's mineral tonnage output.

Generally, mining is either done from the surface or underground.

Surface mining often alters the land characteristics, shape, topography, and geological make up.

Mining can also occur with both surface and underground operations taking place on the same reserve.

Surface mining involves quarrying which is excavating minerals by means of machinery such as cutting, cleaving, and breaking.
