Mining
Dewatering:
Construction dewatering, unwatering, or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed, construction site, caisson, or mine shaft, by pumping or evaporation. On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. This frequently involves the use of submersible “dewatering” pumps, centrifugal (“trash”) pumps, eductors, or application of vacuum to well points. To transfer the water with HM Flex Mine layflat hose would be the cost effective and leak free part of the process.
HM Flex Mine HP hose is an extra tough abrasion resistant hose ideal for pumping the ground water with the aggregates.
HM Flex Mine High Pressure (HP) hose would be an ideal solution for dewatering applications. Higher pressure rated hose needed especially vertical drops at the mining site. HM Flex Mine HP hose comes with 600psi working pressure and 1200psi burst pressure. We can even build higher psi rated hose upon request.

Tunnel Mining and Dewatering:
Tunnels are an increasingly important element in today’s infrastructure. Not only are they used to provide an easy crossing through mountainous regions for road and rail-bound traffic. Increasingly they are also used in urbanized areas to augment over-loaded roads, to provide quicker routes through crowded cities, and to reduce noise and pollution impacts on residents.
Given increasing environmental concerns and greater emphasis on water conservation and recycling the use of mechanical separation technology with centrifuges has become increasingly accepted in mining and quarrying where large quantities of water are used for a variety of processes. These processes generate a high content of fine particles that must be separated. Also, natural water penetrations have to be pumped out from the tunnel with the most flexible heavy duty hose system.
Aggregates such as sand and gravel are mined and the unwanted components are typically removed in a separation process where the gravel is sieved and separated in different size ranges. In order to clean and classify the different gravel fractions, a significant amount of water is needed and the remaining fine sediment is usually pumped into lagoons, ponds or clarifiers that must later be dredged, pumped or drained to separate and dewater the accumulated material.
