- Types of mine shafts include12:
- Long-wall mining: where a long wall of coal is mined in a single slice.
- Sub-level caving: where levels of the ore are blasted by explosives.
- Block caving: where large areas of the ore body are blasted and then extracted with the assistance of gravity.
- Vertical shafts (rock shaft, service shaft, and ventilation shaft) are common in underground mines3.

Shaft sinking - Wikipedia
Mine shafts are vertical or near-vertical tunnels, which are "sunk" as a means of accessing an underground ore body, during the development of an underground mine.
The shape (in plan view), dimensions and depth of mine shafts vary greatly in response to the specific needs of the mine they are part of and the geology they are sunk through. For example, in North and South America, smaller shafts are designed to be rectangular in plan view with timber supports. …Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 11 mins
