Centex has been entrusted with developing an entire dewatering system for a gold mine. We evaluated the existing system and identified potential pitfalls. With the mines, engineering, and planning teams, we worked through various scenarios and came up with a progressive dewatering scheme that makes provisions for the dewatering through to 2028. We designed a custom solution from the floating suction intakes at the pit bottom to transfer pump stations.
Our Packaged Transfer Pump Station is equipped with high-head Cornell pumps capable of heads exceeding 200m that are strategically positioned in the pit. Each packaged transfer station is dimensionally the same footprint as a 12m (40ft) ISO 1AA shipping container to allow for ease of transport that can also be dragged or pushed into position using on-site earthmoving equipment.
The transfer pump station doubles up as a stilling chamber to avoid sediment carryover. Each stage is identical for spare parts interchangeability and ultimate flexibility as the mine plans change. We are looking forward to commissioning these on-site. Stay tuned for some on-site photos.
