In 2018, coal mining decreased to 755 million short tons, and American coal consumption reached its lowest point in nearly 40 years. [17] In 2017, U.S. coal mining had increased to 775 million short tons. [3] In 2016, US coal mining declined to 728.2 million short tons, down 37 percent from the peak production of 1,172
In a particularly spectacular case in the German Saar region (another historical coal-mining area), a suspected mine collapse in 2008 created an earthquake measuring 4.0 on the Richter magnitude scale, causing some damage to houses. Previously, smaller earthquakes had become increasingly common and coal mining was temporarily suspended in the area.
Machinery trying to mine the coal may not be able to reach the displaced seam, if the displacement is too large. Coal mines use a combination of boreholes and high-resolution seismic reflection data to identify the larger faults and avoid the most faulted areas at the mine planning stage. [1]
This summary is based largely on the summary provided by the Congressional Research Service, a public domain source. [1]The Preventing Government Waste and Protecting Coal Mining Jobs in America would amend the Surface Mining Control and Reclamation Act of 1977 to require state programs for regulation of surface coal mining to incorporate the necessary rule concerning excess spoil, coal mine ...
However, it also made the job even more dangerous. Coal mining disasters, such as the Harlan County mining disaster of 1976, were not uncommon and resulted in numerous fatalities. Throughout the 20th century, coal mining remained a major industry in eastern Kentucky, providing jobs and economic growth to the region.
The explosion occurred at 3:27 pm local time (19:27 UTC) on Monday, April 5, 2010, at the Upper Big Branch South Mine near the community of Montcoal, about 30 miles (48 km) south of Charleston. The mine was operated by the Performance Coal Company, a subsidiary of Massey Energy. [2]
Environmental activism has tended to be a divisive issue because of the dependence of the regional economy on extractive industries, including coal mining. [4] Environmental disasters related to coal mining include coal seam fires ( Carbondale mine fire , Centralia mine fire , and Laurel Run mine fire ) and coal slurry spills.
West Virginia is the largest coal-producing state in Appalachia, and the second-largest coal-producing state in the United States, accounting for about 11% of the nation's total coal production in 2014 (the largest coal-producing state is Wyoming, which lies in the Western coal region and accounts for 40% of U.S. coal production).
