Blackwater (coal)
Blackwater is a form of pollution produced in coal preparation plant, coal preparation. In its purification, coal is crushed in a coal preparation plant and then separated and transported as a coal slurry, From the slurry, incombustible materials are removed and the coal can be sized. After the recovery of the coal particles from this slurry, the remaining water is black, contains very fine particles of coal. This blackwater cannot be industrial wastewater treatment, processed in a water treatment plant. Disasters Impoundments for storage of blackwater and other coal-related wastes have a troubled history with often severe environmental consequences. In February 1972, three dams holding a mixture of coal slurry in Logan County, West Virginia failed in succession: of toxic water were released in the Buffalo Creek Flood. As discussed in the book The Buffalo Creek Flood: An Act of Man, out of a population of 5,000 people, 125 people were killed, 1,121 were injured, and over 4, ...

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...

Act Of God
In legal usage in the English-speaking world, an act of God is a natural hazard outside human control, such as an earthquake or tsunami, for which no person can be held responsible. An act of God may amount to an exception to liability in contracts (as under the Hague–Visby Rules) or it may be an "insured peril" in an insurance policy. In Scots law the equivalent term is ''damnum fatale''. By contrast, other extraordinary man-made or political events are deemed '' force majeure''. Contract law In the law of contracts, an act of God may be interpreted as an implied defense under the rule of impossibility or impracticability. If so, the promise is discharged because of unforeseen occurrences, which were unavoidable and would result in insurmountable delay, expense, or other material breach. Under the English common law, contractual obligations were deemed sacrosanct, so failure to honour a contract could lead to an order for specific performance or internment in a debtor' ...

Environmental Impact Of The Coal Industry
The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products. In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain mercury, uranium, thorium, arsenic, and other heavy metals. Coal is the largest contributor to the human-made increase of carbon dioxide in Earth's atmosphere. There are severe health effects caused by burning coal. According to a report by the World Health Organization in 2008, coal particulates pollution are estimated to shorten approximately 10,000 lives annually worldwide. A 2004 study commissioned by environmental groups, but contested by the United States Environmental Protection Agency, concluded that coal burning costs 24,000 lives a year in the United States.

Little Blue Run Lake
Little Blue Run Lake or Little Blue Run is the largest coal ash impound in the United States. FirstEnergy owns the site, located in Western Pennsylvania and parts of the Northern Panhandle of West Virginia, and has disposed of billions of gallons of coal waste into the body of water. Several court cases have been brought against the company as a result of the damage caused by the company's practices at the site. Description The artificial lake was completed in 1975 and is located in both Beaver County, Pennsylvania and Hancock County, West Virginia and is owned by FirstEnergy, a publicly traded company with assets worth $48 billion in 2010. Before Little Blue Run Lake was created, the power company told local residents that the project would create a local recreational and boating area. The lake covers 1,900 acres and the waste in the lake is prevented from escaping thanks to a 400-foot tall, 2,200-foot wide rock-and-earth dam. The dam containing Little Blue Run Lake has been give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingston Fossil Plant Coal Fly Ash Slurry Spill
The Kingston Fossil Plant coal fly ash slurry spill was an environmental and industrial disaster that occurred on Monday December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, releasing of coal fly ash slurry. The coal-fired power plant, located across the Clinch River from the city of Kingston, used a series of ponds to store and dewater the fly ash, a byproduct of coal combustion. The spill released a slurry of fly ash and water, which traveled across the Emory River and its Swan Pond embayment, onto the opposite shore, covering up to of the surrounding land. The spill damaged multiple homes and flowed into nearby waterways including the Emory River and Clinch River, both tributaries of the Tennessee River. It was the largest industrial spill in United States history. The initial spill, which resulted in millions of dollars worth of property damages and rendered many properties unin ...

Martin County Sludge Spill
The Martin County coal slurry spill was a mining accident that occurred after midnight on October 11, 2000, when the bottom of a coal slurry impoundment owned by Massey Energy in Martin County, Kentucky, broke into an abandoned underground mine below. The slurry came out of the mine openings, sending an estimated of slurry down two tributaries of the Tug Fork River. By morning, Wolf Creek was oozing with the black waste; on Coldwater Fork, a stream became a expanse of thick slurry. The spill, which contained arsenic and mercury, killed everything in the water. It was over five feet deep in places and covered nearby residents' yards. The spill polluted hundreds of miles () of the Big Sandy River and its tributaries and the Ohio River. The water supply for over 27,000 residents was contaminated, and all aquatic life in Coldwater Fork and Wolf Creek was killed. The spill was 30 times larger than the Exxon Valdez oil spill, spilling . It was one of the worst environmental disas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberfan Disaster
The Aberfan disaster was the catastrophic collapse of a colliery spoil tip on 21 October 1966. The tip had been created on a mountain slope above the Welsh village of Aberfan, near Merthyr Tydfil, and overlaid a natural spring. Heavy rain led to a build-up of water within the tip which caused it to suddenly slide downhill as a slurry, killing 116 children and 28 adults as it engulfed Pantglas Junior School and a row of houses. The tip was the responsibility of the National Coal Board (NCB), and the Aberfan Disaster Tribunal, subsequent inquiry placed the blame for the disaster on the organisation and nine named employees. There were seven spoil tips on the hills above Aberfan; Tip 7—the one that slipped onto the village—was started in 1958 and, at the time of the disaster, was high. In contravention of the NCB's procedures, the tip was partly based on ground from which springs emerged. After three weeks of heavy rain the tip was saturated and approximately of spoil slipped ...

Coal Preparation Plant
300px, A coal "washer" in Eastern Kentucky A modern coal breaker in Mahanoy City, Pennsylvania combines washing, crushing, grading, sorting, stockpiling, and shipping in one facility built into a stockpile of anthracite coal below a mountain top strip mine A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships. The more of this waste material that can be removed from coal, the lower its total ash content, the greater its market value and the lower its transportation costs. Run-of-mine (ROM) coal The coal delivered from the mine that reports to the coal preparation plant is called run-of-mine, or ROM, coal. This is the raw material for the CPP, and consists of co ...
