What is the entrance to a horizontal mine called?

Explanation:
An adit is the entrance. In mining terms, an adit is a shallow, near-horizontal passage cut from the surface into a mine to provide access, ventilation, and drainage. It’s built along the level of ore near the surface or on a hillside, so it doesn’t require a deep vertical shaft. A shaft is vertical, used to reach deeper levels; a drift and a gallery are horizontal passages inside the mine but not the surface entry. So for a horizontal entrance from the surface into a mine, adit is the correct term.
