Catch ditches are one of the most cost effective rock fall protection measures used in open pit. The ditch, placed along ramps and at the top of the high walls, should be covered by a layer of gravel in order to absorb the energy of falling rocks and it should have an adequate dimension determined by field tests and American modelling.

Rock or Solid Mine Waste. Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock or overburden must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, there is additional waste rock that must be separated from the ore.
