underground mines
Tunnels for ore
Underground mines are excavations beneath the earth's surface for extracting minerals, coal, or ore.
Unlike open-pit mining, underground mining follows seams or deposits deep into the ground through shafts and tunnels.
The underground mines in West Virginia have operated for over a century.
The term also describes the physical spaces themselves: dark, enclosed networks where miners work.
