    A reliable dewatering plan is essential to ensuring a steady supply of process water throughout a mine site. Conversely, the removal of excess water from working areas to allow excavation also

  • Mine dewatering Wikipedia

    Mine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine workings. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to the viability of the mine and may require the use

  • Blog | Mine Dewatering

    Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a pre-requisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.

  • Optimizing Dewatering Processes in Mining Operations

    and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively man- aged dewatering processes typically employ continu-ous water level monitoring. Mine dewatering is usually undertaken for several reasons: • Ensure stability of mine walls during and after . excavation —In open-pit mines, a

  • Mine Dewatering | Waterloo Hydrogeologic

    Mine Dewatering. Open pits are developed in the mining industry for the extraction of minerals, raw materials, and aggregate. In many circumstances, these pits are excavated below the water table. Depending on the geologic environment and proximity of streams, rivers, ponds and lakes, significant groundwater inflows may occur. The magnitude of these inflows must be estimated so that pumping
