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 ...

Coal Fines Sludge Dewatering | Geofabrics

The waste slurry from the CHPP, is directed into settling ponds or tailings dams, however in order to reduce waste, many mines recover the coal fines for further processing. The slurry can either be processed in a series of centrifuges and cyclones to remove water and separate the coal fractions however this is an expensive mechanical process.
