Description

The material being removed by underground feeders can be particularly dangerous! Two Major hazards exist –
  1. The weak material around the draw hole; and
  2. The possibility of hidden cavities (bridged material)
As the underground feeder(s) remove material, a draw hole is formed. The top edge of the draw hole is very unstable and is always near collapse. When a dozer is operated close to the edge, it can induce a slope failure and slide down into the draw hole.
