  • Open-Pit Dewatering: How It Works, and What Pump to Use

    Getting It Out, and Keeping It out.Submersible Slurry PumpsDry-Priming Trash PumpsWhere Does This Water Go?General rule of thumb: The deeper the pit, the more water you’ll encounter. You need to get it out, and keep it out.There are two steps. Both need solutions, and these solutions are mutually exclusive. The water in the open pit has to be removed, but it’ll return unless you also lower the groundwater level. A wellpoint dewatering system around the perimeter of your construction site will take care of lowering the groundwater level.With that solution underway, it’s time to focus on dewatering.

  • Open-Pit Mining Methods

    Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
