Drift: More common way of mining, entering from a horizontal plane and generally in a hill or mountain.
Shaft: Nearly vertical mine shaft going up and down (no entrance from below.)

Open Pit: As shown in picture, mining into a pit or burrow and extracting the minerals.
Mountain Top Removal: Mining of a summit, removing land and gaining minerals such as coal.
