Coal Authority

The Coal Authority’s stated purpose is to:[2]

• keep people safe and provide peace of mind
• protect and enhance the environment
• use its information and expertise to help people make informed decisions
• create value and minimise cost to the taxpayer

The Coal Authority provides services to other government departments and agencies, local governments and commercial partners, while contributing to the delivery of the government’s Industrial Strategy and the 25 year Environment Plan.

As a public body that holds significant geospatial data it is also working with the Geospatial Commission to look at how, by working together, it can unlock significant value across the economy.

As part of the Coal Authority’s duty to protect the public and the environment, it operates a 24-hour telephone line for reporting coal mine hazards and operates 75 mine water treatment schemes across the UK, cleaning more than 122 billion litres of mine water every year. [3]

The Coal Authority has an independent board responsible for setting its strategic direction, policies and priorities, while ensuring its statutory duties are carried out effectively. Non-executive directors are recruited and appointed to the board by the Secretary of State for BEIS. Executive directors are recruited to their posts by the board and appointed to the board by the Secretary of State for BEIS.

It was established under the Coal Industry Act 1994 to manage some functions, in which the British Coal Corporation (formerly the National Coal Board) had previously undertaken, including ownership of unworked coal. Its offices are in Mansfield, Nottinghamshire. It was funded by the Department for Business, Enterprise and Regulatory Reform, and now the Department for Business, Energy and Industrial Strategy (headed by Andrea Leadsom) funds it.

The Coal Authority’s public task comprises all the functions, duties and responsibilities is set out in the following documents

• The Coal Industry Act 1994 (“the 1994 Act”)
• The Coal Mining Subsidence Act 1991, as amended by the 1994 Act
• A Revised Coal Authority Explanatory Note, produced by the Department of Trade and Industry (DTI) for Parliament in June 1994 to explain the intended provisions of the Coal Industry Bill
• The Water Act 2003
• The Water Environment and Water Services act. (Scotland) Act 2003
• Statement by Lord Strathclyde in 1994 on the government’s expectations of the Coal Authority relating to mine water remediation
• Re-statement by John Battle MP in 1998 that the Coal Authority is the designated body with responsibility for dealing with mine water discharges from former coal mines;
• Energy Act 2011

Its headquarters are in Mansfield, Nottinghamshire, where its Mining Heritage Centre is also based. This archive houses a large quantity of data, including historical information, relating to coal mining in the United Kingdom.

The unique collection of around 120,000 coal abandonment plans, covering both opencast and deep mining operations, dates as far back as the 17th century and depict areas of extraction and the point of entry into the same .

Historical mine plans can be accessed for research purposes, for desktop studies prior to development or simply by members of the public with an interest in the history of mining.

The Coal Authority also has a large collection of more than 47,000 British Coal photographs, which feature a wide range of collieries and cover every aspect of coal mining.

All plans and photographs have been digitally scanned and are available to any interested parties. They can be viewed at the Mining Heritage Centre in Mansfield.

To tackle the water pollution caused by historical metal mining in England, the Coal Authority works with the Environment Agency in the Water and Abandoned Metal Mines partnership, funded by the Department for Environment, Food and Rural Affairs. [4]

The Coal Authority’s Commercial Reports and Advisory Services provides comprehensive mining report services, include desktop reports, pre planning advice, project management and civil, structural and environmental engineering. Reports available from the Coal Authority include: [5]

• CON29M Coal mining report – an official coal mining report for the conveyancing industry
• Ground Stability report – a CON29M report, combined with non-coal related British Geological Survey subsidence information
• Enviro All-in-One report – a CON29M report, combined with Groundsure’s homebuyers environmental report
• No Search Certificate – a certificate to show that a property is not within a known area of past, present or proposed future mining activity

Abandoned coal mines are a source of geothermal energy, and could also be used for cooling and storing inter-seasonally waste or renewable energy.

As mines become flooded they have the potential to meet all of the heating needs of the coalfield communities which account for 25% of UK population.[6] In the case of a district heating network, this energy can be transferred to a pipe network using a heat exchanger, and then distributed to nearby homes.

Abandoned coal mines present an opportunity to the UK as a source of geothermal energy, and this is being explored by the Coal Authority, which is working in partnerships with local authorities and other companies to fulfil this potential.[7]

A working example of a district heating scheme using geothermal energy from former mines is being built at Seaham Garden Village, County Durham. It is being developed in partnership with Durham County Council and Tolent Construction. [8]

Seaham Garden Village, a development of more than 1,400 homes, will be built next to the Coal Authority’s Dawdon mine water treatment scheme, with work scheduled to start in the summer of 2020. This scheme protects vital drinking water abstraction from Durham Magnesian Limestone, and pumps 100 to 150 litres of mine water per second to the surface for treatment. This mine water is warmed by geothermal processes to provide a continuous supply of water at 18 to 20°C.

With mine water temperatures unaffected by seasonal variations, there is a potential 6MW of low cost, low carbon sustainable energy available for local space heating use from the Dawdon treatment scheme throughout the year.[9]

The Coal Authority provides consultancy services on: [10]

• Geothermal energy from abandoned coal mines

Geothermal energy from abandoned coal mines is a low carbon, sustainable heat source which under the right conditions can compete with public supply gas prices.

• Coal mining risk assessments

When submitting a planning application within a high risk area, it is likely a Coal Mining Risk Assessment will need to be submitted.

• Mine water treatment schemes

It provides expert advice and assistance to help developers understand and investigate the risks of past mining.

• Tip inspection and management

It has expertise in the long term management of the risks associated with tips and delivering inspection programmes to mitigate these risks.

• Water level monitoring

The Coal Authority has significant experience gained in monitoring an extensive mine water treatment scheme portfolio

• Engineering design

It has a team experienced in engineering design, with many years of providing the critical information required to complete complex civil engineering projects.

• Borehole drilling advice

The complex nature of mine workings can cause operational issues when drilling boreholes, which requires specialist knowledge to be carried out accurately.

• Mining hydrogeology

It has a team of hydrogeologists with a wide range of experience in all types of hydrogeology, specialising in complex mining hydrogeology.
