## Narrative

The surface supply track hoist rope cable became kinked when the system was placed in automatic to lower supplies into the mine and the track switch on the surface was left thrown for the surface supply yard and not the slope track. This allowed the hoist rope to overlap and kink in the slack that was created. The overlap switch was found to be bad.
