Surface Facilities
On the surface above the shaft stands a building known as the headframe (or winding tower, poppet head or pit head). Depending on the type of hoist used the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground). The headframe will also contain bins for storing ore being transferred to the processing facility. If the shaft is used for mine ventilaton, a plenum or casing is incorporated into the headframe to ensure the proper flow of air into and out of the mine.
