Investigation of Dynamic Load in Superdeep Mine Hoisting Systems Induced by Drum Winding

Blair mine hoists powered by drum winding are a key equipment in the transportation of a superdeep mine shaft. The step changes of hoisting velocity and acceleration caused by coil and layer crossover of rope winding on the LeBus drum, which will excite impact responses of hoisting systems, cannot b...
