coal mining with water pump

Coal and Water Pollution | Union of Concerned Scientists

Coal is more often associated with billowing smokestacks than it is with water. But virtually every stage of coal's lifecycle—from mining to processing to burning—can impact local water supplies, sometimes with devastating effect.

Pump | engineering |

Pump: Pump, a device that expends energy in order to raise, transport, or compress fluids. The earliest pumps were devices for raising water, such as the Persian and Roman waterwheels and the more sophisticated Archimedes screw (q.v.).

Glossary of Mining Terms -

Abutment — In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back ...

Mine Services - Water | Introduction | underground COAL

Water. Large quantities of water are used in mining operations for cooling machinery, dust suppression, cleaning, fire-fighting and drinking. Water supplies are normally carried in steel pipes from surface to points close to the work places, with flexible hoses used for the final connections.

Coal mining |

Coal mining: Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy.

How is water managed and treated in mining -

In order to comply with regulations and ensure that the quality of water leaving mine sites is not adversely affecting water users downstream, mining companies develop sophisticated water management plans to minimize the potential for water contamination, and to prevent the release of polluted water into the environment.
