3.3.4 Hoisting
In every underground mine, the ore, waste rock and miners has to be brought up to the surface. Rudimentary wooden equipment designed for this purpose prior to the 19th century already comprised the basic features of modern-day haulage systems: a hoist, a headframe and an elevator.

Hauling large quantities of rocks and ore from increasing depths required the use of high-capacity hoists and careful control of their operation to ensure that miners could move around safely and that ore was continually brought to the surface. Both were crucial to extraction and to processing activities at the surface.
