Understanding mine water treatment Mine water, acid mine drainage and ochre As coal mining in the UK has reduced, some arrangements to pump water out of the mines have stopped. This has allowed iron, found in the rocks within mine workings, to mix with underground water.
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.
High pressure and water spray pump stations for longwall mining A reputable supplier in coal mining for more than 100 years . Since its founding more than 100 years ago, Hauhinco has been closely linked with underground coal mining.
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 ...
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.

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.
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.
Nov 04, 2011· An Illinois coal-mining company was using a sewage-style submersible dewatering pump at the bottom of a 3,000-gallon runoff pond that collects thick slurry draining from several raw and clean coal piles. The water in the pond is so abrasive and acidic that the company was getting no more than six months of use out of each pump. The Solution ...
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 ...
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.
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.
