Groundwater is a common problem during mining, and developing a mine below groundwater level presents many challenges.

Also check out our deep-well dewatering solution.

Poorly controlled groundwater will have negative impacts on the safety, efficiency and economics of mining operations.

The source of surface water in open pit mines are:

  • Stormwater
  • Snow melt
  • Mining operations
  • Sepage from pit walls

Generally, there are 2 main approaches to this issue.

1) Groundwater control by exclusion

Groundwater is prevented by installing cut-off walls around the site.

Methods used to form cut-off walls

  • Displacement barriers
  • Excavated barriers
    They’ll build concrete diaphragm walls, bored pile walls, slurry walls and trenches.
  • Injected barriers
    Examples are rock grouting, jet grouting, etc.

2) Groundwater control by pumping

This method involves using dewatering pumps and tends to be more favourable.

The benefits

  • More efficient working conditions due to better trafficking and diggability
  • Reduced blasting costs
  • Since dry ore and water rock weigh less than wet material, dewatering provides lower haulage costs.
  • Improved slope stability and safety

Our solution

We provided a Pioneer diesel dewatering pump PPSK66S14L2 to an open pit mine here in Australia.

The diesel driven, hardened stainless steel pump was mounted onto a skid base to ensure maximum mobility around the mine.

It is auto prime and powered by a powerful 1500 litres Cat diesel engine.
