upcast

Mine ventilation shaft

Upcast describes something thrown or directed upward: an upcast glance, an upcast stone.

In mining, an upcast shaft brings air up from below ground, ventilating the tunnels.

The word also serves as a noun for the shaft itself or for anything cast upward.

Upcast is the opposite of downcast in its literal, directional sense.
