MINE DEVELOPMENT – ACCESS TO DEPOSIT
Shaft system. Shaft operating costs (Table IX) are based on rates provided by a South African shaft-sinking company based a production rate of 80 000 t/month. The size, speed, and cycle time of the skip based on a 20 t skip travelling at 15 m/s was used as a basis for estimating the shaft operating costs.

Drive Shafts
A shaft is a rotating or stationary component which is normally circular in section. A shaft is normally designed to transfer torque from a driving device to a driven device. If the shaft is rotating, it is generally transferring power and if the shaft is operating without rotary motion it is simply transmitting torque and is probably resisting ...
