* Adits are horizontal tunnels that are driven into the side of a hill or mountain, following the vein of ore. They are often used to access underground mines.
* Drifts are similar to adits, but they may be driven at a slight angle. They are often used to connect different parts of an underground mine.
Here are some other terms that may be used:
* Stope: A large underground excavation where ore is extracted.
* Shaft: A vertical or inclined tunnel that connects the surface to an underground mine.
* Level: A horizontal passageway in an underground mine.
The specific terminology used can vary depending on the type of mining operation and the location.
