process steps to shaft mining of gold from lithosphere

Mining and mineral processing The lithosphere Siyavula

Shaft mining is needed to reach the gold ore. After the initial drilling, blasting and equipping of a mine shaft, tunnels are built leading outwards from the main shaft so that the gold reef can be reached. Shaft mining is a dangerous operation, and roof supports are needed so that the rock does not collapse.

lithosphere Definition Facts Britannica

Lithosphere, rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle.It extends to a depth of about 60 miles (100 km). It is broken into about a dozen separate, rigid blocks, or plates (see plate tectonics).Slow convection currents deep within the mantle, generated by radioactive heating of the interior, are believed to cause the lateral ...

Underground mining (hard rock) - Wikipedia

The mining method selected is determined by the size, shape, orientation and type of orebody to be mined. The orebody can be narrow vein such as a gold mine in the Witwatersrand, the orebody can be massive similar to the Olympic Dam mine, South Australia, or Cadia-Ridgeway Mine, New South Wales.The width or size of the orebody is determined by the grade as well as the distribution of the ore.
