Mining is the extraction of valuable geological materials and minerals from the Earth and other astronomical objects. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.
Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a "pit", and above-ground mining structures referred to as a "pit head". In Australia, "colliery" generally refers to an underground coal mine.
The United Mine Workers of America is a North American labor union best known for representing coal miners. Today, the Union also represents health care workers, truck drivers, manufacturing workers and public employees in the United States and Canada. Although its main focus has always been on workers and their rights, the UMW of today also advocates for better roads, schools, and universal health care. By 2014, coal mining had largely shifted to open pit mines in Wyoming, and there were only 60,000 active coal miners. The UMW was left with 35,000 members, of whom 20,000 were coal miners, chiefly in underground mines in Kentucky and West Virginia. However it was responsible for pensions and medical benefits for 40,000 retired miners, and for 50,000 spouses and dependents.
Maesteg is a town and community in Bridgend County Borough, Wales. Maesteg lies at the northernmost end of the Llynfi Valley, close to the border with Neath Port Talbot. In 2011, Maesteg had a population of 20,612. The English translation of Maesteg is 'fair field'.
South Wales is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia.
The National Coal Board (NCB) was the statutory corporation created to run the nationalised coal mining industry in the United Kingdom. Set up under the Coal Industry Nationalisation Act 1946, it took over the United Kingdom's collieries on "vesting day", 1 January 1947. In 1987, the NCB was renamed the British Coal Corporation, and its assets were subsequently privatised.
The American Coalition for Clean Coal Electricity is a U.S. non-profit advocacy group representing major American coal producers, utility companies and railroads. The organization seeks to influence public opinion and legislation in favor of coal-generated electricity in the United States, placing emphasis on the development and deployment of clean coal technologies.
The National Mining Association (NMA) is a United States trade organization that lists itself as the voice of the mining industry in Washington, D.C. The NMA was formed in 1995, and has more than 250 corporate members.
Consol Energy Inc. is an American energy company with interests in coal headquartered in the suburb of Cecil Township, in the Southpointe complex, just outside Pittsburgh, Pennsylvania. In 2017, Consol formed two separate entities: CNX Resources Corporation and CONSOL Energy Inc. While CNX Resources Corp. focuses on natural gas, spin-off Consol Mining Corporation, now Consol Energy Inc. focuses on coal. In 2010, Consol was the leading producer of high-BTU bituminous coal in the United States and the U.S.'s largest underground coal mining company. The company employs more than 1,600 people.
The Surface Mining Control and Reclamation Act of 1978 (SMCRA) is the primary federal law that regulates the environmental effects of coal mining in the United States.
The Western Fuels Association is a $400 million consortium of coal suppliers and coal-fired utilities based in Westminster, Colorado. Western Fuels Association supplies coal and transportation services to consumer-owned electric utilities in the Great Plains, Rocky Mountain and Southwest regions.
The Coal Authority is a non-departmental public body of the United Kingdom government sponsored by the Department for Energy Security and Net Zero (DESNZ). On behalf of the country, it owns the vast majority of unworked coal in Great Britain, as well as former coal mines, and undertakes a range of functions including:
The mining of minerals in Nigeria accounts for only 0.3% of its gross domestic product, due to the influence of its vast oil resources. The domestic mining industry is underdeveloped, leading to Nigeria having to import minerals that it could produce domestically, such as salt or iron ore. The rights to ownership of mineral resources is held by the Federal Government of Nigeria, which grants titles to organizations to explore, mine, and sell mineral resources. Organized mining began in 1903, when the Mineral Survey of the Northern Protectorates was created by the British colonial government. A year later, the Mineral Survey of the Southern Protectorates was founded. By the 1940s, Nigeria was a major producer of tin, columbite, and coal. The discovery of oil in 1956 hurt the mineral extraction industries, as government and industry both began to focus on this new resource. The Nigerian Civil War in the late 1960s led many expatriate mining experts to leave the country. Mining regulation is handled by the Ministry of Solid Minerals Development, who are tasked with the responsibility of overseeing the management of all mineral resources in Nigeria. Mining law is codified in the Federal Minerals and Mining Act of 1999. Historically, Nigeria's mining industry was monopolized by state-owned public corporations. This led to a decline in productivity in almost all mineral industries. The Obasanjo administration began a process of selling off government-owned corporations to private investors in 1999. The Nigerian Mining Industry has picked up since the "Economic Diversification Agenda", from Oil & Gas, to Agriculture, Mining, etc., began in the country.
Mining in the United Kingdom produces a wide variety of fossil fuels, metals, and industrial minerals due to its complex geology. In 2013, there were over 2,000 active mines, quarries, and offshore drilling sites on the continental land mass of the United Kingdom producing £34bn of minerals and employing 36,000 people.
Coal mining in the United Kingdom dates back to Roman times and occurred in many different parts of the country. Britain's coalfields are associated with Northumberland and Durham, North and South Wales, Yorkshire, the Scottish Central Belt, Lancashire, Cumbria, the East and West Midlands and Kent. After 1972, coal mining quickly collapsed and had practically disappeared by the 21st century. The consumption of coal—mostly for electricity—fell from 157 million tonnes in 1970 to 18 million tonnes in 2016, of which 77% was imported from Colombia, Russia, and the United States. Employment in coal mines fell from a peak of 1,191,000 in 1920 to 695,000 in 1956, 247,000 in 1976, 44,000 in 1993, and to 2,000 in 2015.
The Central Mine Planning and Design Institute is a subsidiary of Coal India Limited which is under the ownership of the Ministry of Coal, Government of India, engaged in the field of environmental engineering and provides consultancy and engineering services across the globe. It is a public sector undertaking under the Government of India and is rated as a Schedule-B and Mini Ratna-II company.
People have worked as coal miners for centuries, but they became increasingly important during the Industrial revolution when coal was burnt on a large scale to fuel stationary and locomotive engines and heat buildings. Owing to coal's strategic role as a primary fuel, coal miners have figured strongly in labor and political movements since that time.
Bentley Colliery was a coal mine in Bentley, near Doncaster in South Yorkshire, England, that operated between 1906 and 1993. In common with many other mines, it suffered disasters and accidents. The worst Bentley disaster was in 1931 when 45 miners were killed after a gas explosion. The site of the mine has been converted into a woodland.
