The most visible feature of a mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. 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.

Friction (or Koepe)  hoists are the most common type of hoist used in Europe, Asia and Australia .The friction hoist was invented in 1877 by Frederick Kope.  Friction hoists are mounted on the ground above the mine shaft, or at the top of the headframe.
The cable hoist machinery had grown more elaborate over the years. Now, as the last and most dramatic improvement began, the Quincy Mine people didn't realize this was the twilight of Upper Peninsula copper mining. Copper mining had been moving out west. So work went ahead, and they finished the world's largest hoist in 1920.

Electric Hoist at Czar Shaft. The Czar engine was an old steam hoist for single-deck cages, built by the Union Iron Works, in San Francisco, about 30 years ago. The gear shaft was lifted out of its bearings, and replaced by another, geared to a 112-h.p. alternating-current motor.
old mine shaft house, which can be seen high on the hill above the town of Hancock. The shaft house, or as it is known locally, the "Quincy No. 2 Rock House," was built above one of the inclined shafts through which the Quincy mine raised the ore to the surface through its No. 2 shaft. The mine has been inoperative since 1945.
The guide made it easy to imagine living during that period, and seeing the mine and equipment first-hand really helped create the picture. We highly recommend visiting Quincy Mine and the items in the gift shop are unique and not to be missed!"
generator plants supply the mine hoists, or for mines using very large Blair multi-rope hoists where the peak power can be in excess of 20 MW. ABB's PSR system works on the concept of inertial energy. The inertial energy of a decelerat-ing mine hoist is captured, stored and reused to limit the peak power of the accelerating mine hoist. 1 2

Mine hoists are the main link between the surface and the below ground levels of an underground mining operation. They are used to transport workers and to bring ore to the surface. A hoist can operate in either a vertical shaft or on an inclined ramp (which is more common for coal mines).
Classified under the category of main types of underground mines, slope mining is quite similar to shaft mine with the exception of that the coal is closer to the surface and passage to the coal is accessed by a burrow that is dug on slant.
Shaft mining Wikipedia. Shaft mining or shaft sinking is excavating a vertical or near vertical tunnel from the top down, . 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 .
