Attribute

UMA Underground Mine Access

Definition

The targeted mineral seam is located below local drainage and does not outcrop at the surface, and is far enough below the surface as to require access to be by means of a vertical shaft.

Description

On the surface above the mine shaft stands a superstructure (termed a 'pit-head' or 'pit-head frame'), which historically contained a winding engine and in modern times contains an electric hoist controller. This raises and lowers a cage within the shaft that serves as a lift for the transportation of minerals, equipment and/or workers.
