design or required pumping rate does not produce a gradient at the interface of the formation and the well filter or at the screen and filter that starts to cause the flow to become turbulent. Therefore, the design of a dewatering system should always be checked to see that the well or wellpoints have adequate wetted screen length h
Historically, mine dewatering design in Southern Africa has been achieved when water has become a problem during mining. The low rainfall and absence of very high yielding aquifers, has meant that the control of mine water inflows were often accommodated in the run of mine design. Designs for coal, gold and diamond open pits are very similar.
Popular Applications for Dewatering Screens Dewatering Screens can be used to dewater 4 mesh particles of sand, coal, iron ore, salt, etc. They can also be used to dewater fines in fines recovery circuits, typically +400 mesh , as well as to rinse and dewater jig discharge nominally 2 .

The dewatering aspects of transition from open pit to underground mine is also covered. You will be educated in the basic theory of mine dewatering and the application of the knowledge to real world situations. The steps required to design and implement a successful and cost effective dewatering strategy will be
the wellpoints, the eductor system uses high pressure water and riser units, each about 30 40 mm in diameter. A high pressure supply main feeds water through a venturi tube immediately above the perforated well screen, creating a reduction in pressure which draws water through the large diameter rise pipe.
Dewatering screens were first introduced to the mining industry nearly 40 years ago as a more efficient means of dewatering minus 6.35mm solids contained in slurries. In most operations they replaced older technology such as screws/spirals or rake classifiers because they delivered a drier product.
