Water

Simulations of open pit mines dewatering, their flooding, and environmental impact assessment are performed using groundwater flow models. They must take into consideration both regional groundwater conditions and the specificity of mine dewatering operations. This method has been used to a great extent in Polish opencast mines since the 1970s.

Mine Dewatering System Design

Dewatering of a surface or underground mine can be a significant production cost. Total costs include both the capital costs for wells, pumps, and water-disposal facilities and the operating costs for pumping, treatment and disposal of the water. Such costs are minimized when the present value of the capital and operating costs is minimized. The dewatering can be accomplished with various

Dewatering Techniques for Construction Projects

Dewatering bags are made of durable geotextile fabric used to filter water by removing sediments. They are used for dredging operations, construction sites, or places with a high water table near the shoreline. These bags should be sized accordingly based on the pump flow rate and type of sediment. When using dewatering bags, avoid multiple pipe discharges as it may cause the filter bag to
