Simulation Testings of Emergency Braking of the Mining Shaft Hoist

摘要

For each mining shaft hoist braking devices shall be provided, which in the event of conveyance overwind the boundary positions, act upon conveyances with braking forces, independently on the brake mounted in a drive. The state, in which the conveyances overwind the boundary positions, is called the shaft hoist emergency braking state. It is the most dangerous emergency event occurring during the shaft hoist operation. Digital simulation of the hoist emergency braking state, carried out on the appropriate model, enables to assess kinematic and dynamic parameters of that process.
