Dewatering pumps for mining are very important on every mining site. Although dewatering can be done by other techniques such as electro-osmosis and gravity flow, the use of dewatering pumps is the most efficient, convenient and fastest in achieving satisfactory results.
Normally, dewatering is done by evaporation or pumping. The type of dewatering pumps to be used depends on the material’s corrosion potential. It involves the use of vertical turbine pumps or submersible pumps. A minor amount of water can be pumped out by creating a sump. Here are some benefits of using dewatering pumps.
Ground excavation
Some ground excavations are jeopardized due to the water table level. The water table can become elevated when it receives more water than it can drain off. This can be from high amounts of rain or a lot of water from higher elevations. Dewatering is done to permit construction and excavation within dry environments as the water table is lowered. This prevents ground subsidence.
Making the soil firm
Draining groundwater is very important as it plays an important role in drying up the soul and making it firm. Dry soil keeps the landscape stable reducing the risk of sediments getting carried off by water.
Providing dry basement
If groundwater is not suitably controlled and managed, it can cause problems for basement construction and excavation. These problems can range from major inflows that lead to instability, to inefficiency in construction operations, to the collapse of the excavation. Getting the right dewatering pumps from the right dewatering pump manufacturers is the best way to ensure you get a dry basement. The excavation can flood due to groundwater inflows from layers of rock or soil that contain water.
Control pore pressure and seepage beneath the pavement
Soil that is composed of fine clays or silts can experience high pore pressure. Since these types of soils have low permeability, dewatering schemes such as vacuum-sealed deep wells or ejector wells may serve to draw water into the well for abstraction.
Job safety
The muddy or wet ground produces unsafe working conditions for employees. The wet soil can cause accidents by tripping workers. Water can obstruct certain tasks. The presence of water can damage the construction equipment or even impede operations.
Technology trends
Currently, the market has a price-sensitive nature. This is becoming a very strenuous factor in the revenue growth of the global market. China is a major producer of cheap pumps and this has disrupted the market. Internal pump manufacturers differentiate their products by integrating this to advanced technologies and providing additional services. Some of these additional services include product customization.
Variable drive controls are currently being used to control dewatering pumps, together with remote management systems and motor protection.
Noise control systems
Buyers all over the world prefer submersible dewatering pumps mining and less noisy products in comparison to those that produce a lot of noise. Although quieter pumps are more expensive due to the soundproofing mechanisms, people still buy them as the pumps are more economical and beneficial over a while.
