Understanding mine water treatment - GOV.UK

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. As this mine water reaches the surface it comes into contact with the air and a chemical reaction takes place.

Coal Mining Effluent Guidelines Effluent

Mine operators extract coal from underground and surface mines using machinery and explosives. Coal remining occurs on mine lands and coal refuse piles that have been previously mined. Coal preparation plants remove waste material from coal by washing and concentrating. The plants may also sort and screen coal by size, and may crush the coal to facilitate handling and processing.

Conversion of coal mine drainage ochre to water

01-09-2015  Ochre is a term for the sludge, predominantly comprising hydrous ferric oxides, that precipitates from coal mine water and is accumulated by treatment systems during the treatment of mine drainage. The existing coal mine water treatment plants in the UK are all managed by the Coal Authority and treat predominantly circumneutral ferruginous mine water and lead to arisings of about

Managing Britain's Coal Mining Legacy - ArcGIS

27-01-2021  The Coal Authority has more than 20 years' experience in resolving the impacts of coal mining in Britain. We were set up to deal with coal licensing, permits, and subsidence damage claims. However, it quickly became evident that the legacy left behind by coal mining was much more complex.

Assessing and managing spontaneous combustion of coal

Most underground mine explosions are due to a build-up of methane which is then ignited by a spark, usually from a piece of equipment or a friction event. However, spontaneous combustion or heating of coal in situ can also act as an ignition source which, together with elevated methane concentrations, will result in a mine explosion.

Lynemouth Mine Water Treatment Scheme

02-09-2020  The first phase of the scheme was constructed by JN Bentley/Coal Authority in 2014. This comprised pumping infrastructure and two 5,000m 2 settlement lagoons capable of treating up to 100l/s of mine water. This slowed the rise of mine water and provided information to determine the longer-term pumping and treatment strategy within the mining block.

Recent developments in coal mine methane

01-04-2016  Chinese safety regulations of coal mine stipulate that the pre-mining coal seam must be pre-drained to decrease the gas pressure and content below the safety margin of 0.74 MPa and 8 m 3 /t, respectively (State Administration of Coal Mine Safety of China, 2011).Otherwise it may easily cause coal-gas outburst, gas exceeding the limit in the working face or even gas explosion accidents.
