If minerals are found deeper, as is the case with most of the gold in South Africa, underground mining is used. Underground mining (shaft mining) South Africa''s thin but extensive gold reefs slope at an angle underneath the ground, and this means that some deposits are very deep and often difficult to reach.
Subsurface mining doesn''t remove the unneeded soils or rock out of the way instead it uses big machines to dig deep underground into deposits that hold the same minerals and energy under the Earth''s surface. Strip mining is where a trench is dug to obtain the materials.
