Appliion of dynamic braking to mine hoisting systems

Appliion of dynamic braking to mine hoisting systems

Abstract: Accidents occurred on counterweighted mine hoisting systems when the mechanical brake failed while the cage was empty. This allowed the counterweight to fall to the bottom of the shaft, causing the cage to overspeed and crash into the headframe. Directcurrent hoist motors have the potential for preventing this type of accident by incorporating a passive electrical braking system

A mining hoist (also known simply as a hoist or winder) is used in underground mining to raise and lower conveyances within the mine shaft.It is similar to an elevator, used for raising humans, equipment, and assorted loads. Human, animal and water power were used to power the mine hoists documented in Agricola''s De Re Metallica, published in 1556.
