Centralia is a borough and near-ghost town in Columbia County, Pennsylvania, United States. It is part of Northeastern Pennsylvania. Its population has declined from 1,000 in 1980 to five residents in 2020 because a coal mine fire has been burning beneath the borough since 1962. Centralia, part of the Bloomsburg–Berwick metropolitan area, is the least-populated municipality in Pennsylvania. It is completely surrounded by Conyngham Township.
Anthracite, also known as hard coal and black coal, is a hard, compact variety of coal that has a submetallic lustre. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals.
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 the above-ground structures are 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.
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground coal mining, although accidents also occur in hard rock mining. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries where safety measures are not practiced as fully. A mining disaster is an incident where there are five or more fatalities.
The Knox Mine disaster was a mining accident on January 22, 1959, at the River Slope Mine in Jenkins Township, Pennsylvania.
The Coal Region is a region of Northeastern Pennsylvania. It is known for being home to the largest known deposits of anthracite coal in the world with an estimated reserve of seven billion short tons.
The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today, but has begun to decline due to the strong contribution coal plays in global warming and environmental issues, which result in decreasing demand and in some geographies, peak coal.
The Coal strike of 1902 was a strike by the United Mine Workers of America in the anthracite coalfields of eastern Pennsylvania. Miners struck for higher wages, shorter workdays, and the recognition of their union. The strike threatened to shut down the winter fuel supply to major American cities. At that time, residences were typically heated with anthracite or "hard" coal, which produces higher heat value and less smoke than "soft" or bituminous coal.
The South Wales Coalfield extends across Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, Rhondda Cynon Taf, Merthyr Tydfil, Caerphilly, Blaenau Gwent and Torfaen. It is rich in coal deposits, especially in the South Wales Valleys.
A coal breaker is a coal processing plant which breaks coal into various useful sizes. Coal breakers also remove impurities from the coal and deposit them into a culm dump. The coal breaker is a forerunner of the modern coal preparation plant.
A breaker boy was a coal-mining worker in the United States and United Kingdom whose job was to separate impurities from coal by hand in a coal breaker.
The history of coal mining in the United States starts with the first commercial use in 1701, within the Manakin-Sabot area of Richmond, Virginia. Coal was the dominant power source in the late 1800s and early 1900s, and although in rapid decline it remains a significant source of energy in 2023.
The Avondale Mine disaster was a massive fire at the Avondale Colliery near Plymouth Township, Pennsylvania, on September 6, 1869. It caused the death of 110 workers. It started when the wooden lining of the mine shaft caught fire and ignited the coal breaker built directly overhead. The shaft was the only entrance and exit to the mine, and the fire trapped and suffocated 108 of the workers. It was the greatest mine disaster to that point in American history.
Haig Colliery was a coal mine in Whitehaven, Cumbria, in north-west England. The mine was in operation for almost 70 years and produced anthracitic coal which is most useful for coking coal. Situated on the coast, the underground workings of the mine spread westwards out under the Irish Sea and mining was undertaken at over 4 miles (6.4 km) out underneath the sea bed.
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.
The Historic Silver Mine, is a UNESCO World Heritage Site in Tarnowskie Góry, Silesia, Poland. The mine and the neighbouring Black Trout Adit are remnants of a silver mining industry. The museum is an Anchor point on the European Route of Industrial Heritage. It also joined The International Committee for the Conservation of the Industrial Heritage and the Silesian Tourist Organization.
Mine safety is a broad term referring to the practice of controlling and managing a wide range of hazards associated with the life cycle of mining-related activities. Mine safety practice involves the implementation of recognised hazard controls and/or reduction of risks associated with mining activities to legally, socially and morally acceptable levels. While the fundamental principle of mine safety is to remove health and safety risks to mine workers, mining safety practice may also focus on the reduction of risks to plant (machinery) together with the structure and orebody of the mine.
On 2 July 2020, a major landslide at the Wai Khar jade mining site in the Hpakant area of Kachin State, Myanmar, killed between 175 and 200 miners in the country's deadliest-ever mining accident. At 06:30 local time (MMT) heavy rains triggered the collapse of a heap of mining waste, which came tumbling down into a lake. This generated a 6.1-meter (20 ft) wave of mud and water that buried those working at the Wai Khar mine. The miners killed or injured by the landslide were independent "jade pickers", who scavenge tailings from larger operators and who live in ramshackle quarters at the base of large mounds of rubble.
