Existing pump technologies are being applied in innovative new ways in an attempt to dramatically reduce the long and short term costs of dewatering mines.
The pump industry has been experiencing an increase in the demand for dewatering pump technologies, as low commodity prices have convinced mining houses to exploit the reserves of marginal mines.
A large number of existing mines are being refurbished, and the dewatering of these mines is playing an integral part in the reconstruction process of those marginal mining activities. Submersible turbine pumps have emerged as a viable, cost-effective alternative to a dewatering application.
Traditionally, pumping stations were built underground near flooded areas of the mine. These required flameproof motors that were flooded every time there was a heavy rainfall. The identification of heavy-duty submersible pumps to dewater mines as an alternative to the former pumping stations, has become a reality and is a viable option for mining houses.
These submersible dewatering pumping systems are easy to install and are considerably more cost-effective as the need to build pumping stations underground is totally eliminated. As the pumps are submerged, there is no requirement for a flameproof system resulting in further cost savings. This system also provides access to areas that were previously inaccessible and which can now be mined as soon as all the water has been pumped out.
