Interesting Features:

  • Suspended conveyor modules hung from the drift tunnel roof/back.
  • ¬†Conveyor CV010 incorporated a horizontal curve at the head end to compensate for poor geological conditions found during construction.
  • Conveyor lift of 470 meters.
  • Flywheels on each conveyor to extend and match drift stop times.
  • Conveyor CV-010 has 900 meter Convex Curve and a 2,100 meter Horizontal Curve.
