A drift mine is a type of underground mining where a horizontal tunnel (drift) is excavated along the mineral deposit. It is typically used to access coal, building materials, and other mineral resources. Drift mines are less expensive and safer to operate compared to shaft mines, making them a common method for extracting materials.
In a mine, a drift refers to a horizontal passageway or tunnel that is excavated for access, ventilation, or transportation of materials. Drifts are typically used for moving workers, equipment, or ore within the mine workings.
A horizontal mine entrance is called an adit. It is a nearly horizontal passage from the surface into a mine for access or drainage.

There are various types of mines in the world, including open-pit mines, underground mines, placer mines, and drift mines. Each type of mine is designed for different geological conditions and extraction methods.

Drift mines are characterized by the use of a level tunnel leading into the mine, while slope mines have an inclined tunnel, and shaft mines utilize a vertical tunnel
This is known as drift mining. The horizontal opening is known as an adit.
Drift mining is the type of mining defined by the horizontal opening, or adit, in a mountain. This is the stereotypical mining found in most media, and is in contrast to quarry mining, mining in open surfaces, or strip mining, where all the materials are taken and then filtered.
An adit. In North America, the horizontal or sloped entrance to a mine is called a "Portal". Portal more specifically refers to the portion of the shaft visible from the outside of the mine. In some areas, the Portal portion of a horizontal shaft is called the "Drift Mouth" or "Drift Portal" as this shaft leads into a "Drift Mine". With a vertical shaft, that portion would be called a "Collar".
A horizontal mine entrance is called an adit. It is a nearly horizontal passage from the surface into a mine for access or drainage.

Although unfamiliar with the term drifting cars, research has provided a number of movies that feature drifting cars. There are a number of movies titled Drift 1, Drift 2, Drift 3, Drift 4, Drift 5, Drift 6 and Drift 7. There are also Drift Special - Beauty Battle, and Drift GTR.
