Water pollution is controlled by carefully separating the water runoff from undisturbed areas from water which contains sediments or salt from mine workings. Clean runoff can be discharged into surrounding water courses, while other water is treated and can be reused, such as for dust suppression and in coal preparation plants.

Old Coal Mines Adapted to Create Geothermal Energy ... Warm water from the mine is brought to the surface where a heat pump extracts the heat in order to supply hot water to s in the area ...
A stream nearby a mining operation allowed to run water mills that were employed to run water pumps to drain the mine workings or to run stamp mills that broke the ore. However the capacity for both ultimately depended on the surface water flow – the more there was, the more work could be done, the deeper the mine could get.
Jul 01, 2016· Mining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires, subsidence, and overused and contaminated water supplies. Mines are quick to dig up and destroy forests and soils. But once the coal is gone, the problems they leave behind, like acid mine drainage, can persist for decades.
FIGURE F-1 Schematic of a room-and-pillar coal mine section. SOURCE: Arch Coal, Inc., 2012. FIGURE F-2 Details of the longwall face. SOURCE: EIA, 1995. There are several variations of each method. However, ever since the introduction of continuous miners in the late 1940s, room-and-pillar continuous mining has been gaining ground over conventional room-and-pillar mining.
Mining. Positive-displacement pumps by NETZSCH have been used for decades reliably in the demanding mining industry. The diverse substances handled in mining include wastewater, mineral slurries, thickened sludges, kaolin suspensions, filtrates, zinc sludges and drilling muds which NEMO ® Pumps are perfectly suited to transport. These abrasive and viscous substances are handled with ease.
"We are hopeful that we can drain out more water after high-capacity submersible pumps – that can pump out 500 gallon of water per minute – of Coal India Limited has reached the site. High-capacity pumps of Kirloskar Brothers Limited are also expected to reach the site by Wednesday," Susngi said.
Oct 05, 2010· Storing coal-mining waste together with the water used to separate it from the coal can present a significant hazard if the impoundments ("slurry ponds") fail or the slurry breaks through into nearby abandoned mines. After extraction, coal must be transported to the power plant.
of water. Mainly three-throw ram pumps and mono pumps belong to this category which is used to pump mine water containing suspended solids. This type of water damages internal component of pumps like valves, seats and scores stators. In addition, there are many example of interruption of coal production by stators burnt out problem due to air
Nov 20, 2018· Coal-Mining Pump Issues That Increase Your Costs There are three coal-mining issues that plague slurry pumps and shorten their lifespans. Abrasive Solids Coal itself is a highly abrasive material. A coal slurry is a muddy, acidic mixture of water, coal chunks, coal fines, dust, dirt and rocks.

Acid mine drainage (AMD) refers to the outflow of acidic water from coal or metal mines, often abandoned ones where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, which can wash into nearby rivers and ...
Dec 08, 2017· Why do we need coal mine water treatment? When a coal mine closes, the pumps that were used to keep the water out of the mine while the mineral was extracted are switched off and removed. Over ...
Mar 17, 2015· Pumps, in their many different designs, perform a large number of vital tasks within the mining industry and as such they can be responsible for certain aspects of mine .
It was the first practical application of the steam engine and it was used to dewater coal and tin mines. The first reliable metal pump was created by József Károly Hell and used in the Schemitz mine in 1749. Almost 40 years later, in 1788, the first water-independent system appears that uses a metal pump.
Historically, mine dewatering design in Southern Africa has been achieved when water has become a problem during mining. The low rainfall and absence of very high yielding aquifers, has meant that the control of mine water inflows were often accommodated in the run-of-mine design. Designs for coal, gold and diamond open pits are very similar.
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.
