mining shafts
Deep vertical excavations
Mining shafts are vertical or steeply inclined passages dug into the earth to access underground mineral deposits.
They serve as the main entry points for miners and equipment, and as routes for extracting ore.
A single mine may have multiple shafts for ventilation, emergency escape, or accessing different levels: The old mining shafts had been sealed for decades.
