Blackjewel LLC
Blackjewel LLC is an American energy company which held a significant portion of the coal mines in the United States. The company became of national importance after its 2019 bankruptcy filling and liquidation. In 2021, a federal bankruptcy judge ruled that the company was allowed to abandon assets without cleaning up the environmental damage of mines in its holdings. These holdings included mountaintop removal, surface mines and coal refuse many of which had significant potential environmental and public health impacts. For example, of 187 mining permits in Kentucky, 150 had 587 outstanding environmental violations, many of which did not have a bond to pay for cleanup. In part the large environmental legacy of the company was caused by the practice of former CEO Jeff Hoops in buying coal assets from companies that were not finding them economically viable. Many of these were acquired from bankruptcies in 2014/2015. At the time of the 2019 filing, the company had 1700 employees i ...

Mountaintop Removal Mining
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams. This process is considered to be safer compared to underground mining because the coal seams are accessed from above instead of underground. In the United States, this method of coal mining is conducted in the Appalachian Mountains in the eastern United States. Explosives are used to remove up to 400 vertical feet (120 m) of mountain to expose underlying coal seams. Excess rock and soil is dumped into nearby valleys, in what are called "holler fills" ("hollow fills") or "valley fills".U.S. Environmental Protection Agency, "Mountaintop Mining/Valley Fills in Appalachia: Final Programmatic Environmental Impact Statement," issued 2005 June 25, available ahttp://www.epa.gov/region03/mtntop/index.htm(accessed 2006 August 20).

Surface Mining
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. In North America, where the majority of surface coal mining occurs, this method began to be used in the mid-16th century and is practiced throughout the world in the mining of many different minerals. In North America, surface mining gained popularity throughout the 20th century, and surface mines now produce most of the coal mined in the United States. In most forms of surface mining, heavy equipment, such as earthmovers, first remove the overburden. Next, large machines, such as dragline excavators or bucket-wheel excavators, extract the mineral. The pros of surface mining are that it has a lower financial cost and is a lot safer than undergrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Refuse
Coal refuse (also described as coal waste, rock, slag, coal tailings, waste material, rock bank, culm, boney, or gob) is the material left over from coal mining, usually as tailings piles or spoil tips. For every tonne of hard coal generated by mining, 400 kilograms of waste material remains, which includes some lost coal that is partially economically recoverable. Coal refuse is distinct from the byproducts of burning coal, such as fly ash. Piles of coal refuse can have significant negative environmental consequences, including the leaching of iron, manganese, and aluminum residues into waterways and acid mine drainage. The runoff can create both surface and groundwater contamination. The piles also create a fire hazard, with the potential to spontaneously ignite. Because most coal refuse harbors toxic components, it is not easily reclaimed by replanting with plants like beach grasses. Gob (short for "garbage of bituminous") has about four times as much toxic mercury and more s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cumberland, Kentucky
Cumberland is a home rule-class city in Harlan County, Kentucky, in the United States. The population according to the 2010 Census was 2,237, down from 2,611 at the 2000 census. History Cumberland was settled in 1837 and named "Poor Fork", for its location on a fork of the Cumberland River with relatively poor soil. It remained isolated until the coal mining boom of the 1900s when railroads connected it with surrounding towns. It was renamed "Cumberland" in 1926. On July 29, 2019, a group of coal miners blocked a coal train on a track in protest when the company they worked for, Blackjewel LLC, refused to pay them after declaring bankruptcy. Blackjewel was founded in 2017, and it was one of the largest coal mining companies in the country. Its bankruptcy filing also affected employees in Virginia and Wyoming; in total about 1700 miners have been affected. The miners called off the protest in late September 2019, mostly because they have found other jobs. They intend to contin ...

2019 Harlan County Coal Miners Protest
The 2019 Harlan County coal miners' protest was a labor protest held by dozens of coal miners in Cumberland, Kentucky. The causes of the protest stemmed from the 2019 bankruptcy of Blackjewel Coal, a coal mining company that operated a mine in the county. Following the company's bankruptcy, former coal miners did not receive payment for several weeks of work, leading to many miners protesting by blocking a coal train on tracks in the county. The protest lasted from July 29 to September 26, with litigation continuing in bankruptcy courts. Background In 2019, Blackjewel, LLC, a subsidiary of Revelation Energy, was one of the largest coal operators in the country. On July 1, 2019, Blackjewel Coal filed for bankruptcy, leading to the abrupt firing of about 1,700 miners in Kentucky, Virginia, West Virginia, and Wyoming. 200 miners in Harlan County were affected. Following this, many of the affected workers reported bounced paychecks and being unable to access their 401(k) accoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coal Companies Of The United States
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
