BENEFITS OVER CONVENTIONAL OPEN PIT & UNDERGROUND MINING


benefits
  • Steeper pit slopes available due to flooding of the pit - ultra low stripping ratio
  • No people in danger in the pit
  • No blasting noise, ground vibration, dust or fume nuisance
  • No dewatering costs

CROSS SECTION OF AN INLAND MINE

Most on-land open pit mines that have reached their economical depth are left to flood. In some cases high-wall mining or underground block caving with vertical ore-bodies follows. The technology SMD offer poses a compelling question: If the stripping ratio has become a limitation, or the costs of setting up an underground mine are prohibitive but the rock is cuttable at productive rates – why not continue collecting the orebody using submerged mineral extraction machines?
