Shaft Sinking for Small-Scale Mining in Africa
Figure 1 depicts a small shaft used to mine tin in Rwanda utilising cage hoisting – whereby a mine car is filled with ore and is hoisted to surface. The stone looks at the practical aspect of artisanal shaft sinking utilising picks and shovels and contrasts this method to a shaft design suitable for small scale miners.
Shaft Mining, Mining Techniques, Underground …
Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earths surface. It is found mostly all over the world.
