mining tunnel
Ore extraction corridor
A mining tunnel is a horizontal or gently sloping passage dug underground to access mineral deposits or coal seams.
Unlike vertical shafts, tunnels allow workers and equipment to move laterally through rock: The mining tunnel extended half a mile into the mountain.
Abandoned mining tunnels pose collapse risks and sometimes become tourist attractions.
