Water for Coal Union of Concerned Scientists

Oct 05, 2010  Water is used to extract, wash, and sometimes transport the coal; to cool the steam used to make electricity in the power plant; and to control pollution from the plant. The acts of mining and burning coal, as well as dealing with the waste, also can have major effects on water

Mining Water Use - USGS

The mining water-use category includes groundwater and surface water that is withdrawn and used for nonfuels and fuels mining. Nonfuels mining includes the extraction of ores, stone, sand, and gravel. Fuels mining includes the extraction of coal, petroleum, and natural gas. Water is used for mineral extraction, quarrying, milling, and other...

Wastewater is generated during the mining process from groundwater produced during coal extraction, from water used by operators for equipment cooling and dust control, and from precipitation entering mines.

ITP Mining: Water Use in Industries of the Future: Mining ...

Water use in mining operations can be divided into three categories: mining, processing, and mineral conveyance. In most types of mining, relatively little water is used in actual ore pro­ duction. A notable exception is underground coal mining, where water is used as one of sev­ eral measures to reduce the hazard of fires or explosions.
