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 earth's surface. It is found mostly all over the world.

Skips are shaft conveyors for hoisting ore/coal or waste from the underground. The most significant feature is the method by which ore/coal is discharg ed from the skip. Skips now in use are almost always the bottom-dump design.
