What Is a Mine Shaft? | An Underground Miner
Shaft mining is an excavation method used to access an underground ore body from the top down. The term "shaft" refers to the vertical tunnels sunk underground for mining and engineering projects.. When the opening starts on the surface, the resulting tunnel is called a shaft. If the vertical tunnel starts underground and pushes upward, it's called a sub-shaft.

Innovations: Introduction to Copper: Mining & Extraction
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...
