Surge piles of mined material at coal mines have inherent hazards for personnel and equipment working on or around them.

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.
