The fire that has been burning for 56 years

Environment Disaster management Energy Pennsylvania Mining

The Centralia mine fire is a coal-seam fire that has been burning underneath the borough of Centralia, Pennsylvania, United States, since at least May 27, 1962. Its original cause is still a matter of debate. It is burning in underground coal mines at depths of up to 300 feet (90 m) over an 8-mile (13 km) stretch of 3,700 acres (15 km2). At its current rate, it could continue to burn for over 250 years. It has caused most of the town to be abandoned: the population dwindled from around 1,500 at the time the fire started to 7 in 2013, and most of the buildings have been levelled.

Oil drilling: Wrong coordinate system creates lake 1,300 feet deep (1980)

Disaster management Geology Mining Lakes

Lake Peigneur (locally pronounced [pæ̃j̃æ̹ɾ]) is a brackish lake in the U.S. state of Louisiana, 1.2 miles (1.9 kilometers) north of Delcambre and 9.1 mi (14.6 km) west of New Iberia, near the northernmost tip of Vermilion Bay. With a maximum depth of 200 feet (60 meters), it is the deepest lake in Louisiana.

It was a 10-foot-deep (3 m) freshwater body, popular with sportsmen, until an unusual man-made disaster on November 20, 1980 changed its structure and the surrounding land.

Sand Theft

Crime Mining

Sand theft or unauthorised or illegal sand mining leads to a widely unknown global example of natural and non-renewable resource depletion problem comparable in extent to global water scarcity. Beach theft is illegal removal of large quantities of sand from a beach leading to full or partial disappearance of the beach.

100 years ago today, the battle of Blair Mountain

United States Military history Military history/North American military history Military history/United States military history Appalachia Mining Organized Labour United States/West Virginia

The Battle of Blair Mountain was the largest labor uprising in United States history and the largest armed uprising since the American Civil War. The conflict occurred in Logan County, West Virginia, as part of the Coal Wars, a series of early-20th-century labor disputes in Appalachia. Up to 100 people were killed, and many more arrested. The United Mine Workers saw major declines in membership, but the long-term publicity led to some improvements in working conditions.

For five days from late August to early September 1921, some 10,000 armed coal miners confronted 3,000 lawmen and strikebreakers (called the Logan Defenders) who were backed by coal mine operators during the miners' attempt to unionize the southwestern West Virginia coalfields when tensions rose between workers and mine management. The battle ended after approximately one million rounds were fired and the United States Army, represented by the West Virginia Army National Guard led by McDowell County native William Eubanks, intervened by presidential order.

Uranium can be extracted from seawater in useful amounts

Energy Mining

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants.

Uranium is mined by in-situ leaching (57% of world production) or by conventional underground or open-pit mining of ores (43% of production). During in-situ mining, a leaching solution is pumped down drill holes into the uranium ore deposit where it dissolves the ore minerals. The uranium-rich fluid is then pumped back to the surface and processed to extract the uranium compounds from solution. In conventional mining, ores are processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching. The milling process commonly yields dry powder-form material consisting of natural uranium, "yellowcake," which is sold on the uranium market as U3O8.
