Mine dewatering - WikipediaDeze pagina vertalen

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 ...

Abstract. Although all deep mining has now ceased in the Durham coalfield of northern England, dewatering still continues (in June 1995) in the central area of the Coal Measures outcrop.Beyond the radius of influence of the dewatering pumps, the water table has already recovered, and several uncontrolled minewater discharges are found.

In the vacuum filtering of coal slurries, dewatering of the filter cake is achieved by contacting the coal with a C 8 to C 20 aliphatic carboxylic acid or a derivative thereof, especially sodium oleate. Reductions in moisture levels are thereby achieved in a cost-effective manner.
