Coal Mining In The United States
Coal mining is an industry in transition in the United States. Production in 2019 was down 40% from the peak production of in 2008. Employment of 43,000 coal miners is down from a peak of 883,000 in 1923. Generation of electricity is the largest user of coal, being used to produce 50% of electric power in 2005 and 27% in 2018. The U.S. is a net exporter of coal. U.S. coal exports, for which Europe is the largest customer, peaked in 2012. In 2015, the U.S. exported 7.0 percent of mined coal. According to the U.S. Energy Information Administration (EIA), in 2015, Wyoming, West Virginia, Kentucky, Illinois, and Pennsylvania produced about , representing 71% of total coal production in the United States. In 2015, four publicly traded US coal companies filed for Chapter 11 bankruptcy protection, including Patriot Coal Corporation, Walter Energy, and the fourth-largest Alpha Natural Resources. By January 2016, more than 25% of coal production was in bankruptcy in the United ...

American Consolidated Natural Resources
American Consolidated Natural Resources, previously known as Murray Energy, is a US-based coal mining company. It is the fourth largest coal producer in the country, and the largest privately-owned coal company. Founded in 1988 by Robert E. Murray, the company filed for bankruptcy in 2019. The company gained notoriety following the collapse of the Crandall Canyon Mine in 2007, following a number of citations and fines for safety practices at the site. According to ''The Guardian'', Murray Coal was responsible for 0.15% of global industrial greenhouse gas emissions from 1988 to 2015. History Murray Energy was founded by Robert E. Murray in 1988 through the acquisition of the Powhatan No. 6 mine in Alledonia, Ohio. The company was established in nearby St. Clairsville, Ohio. The Powhatan mine is the only mine operated by a Murray Energy Corporation independent operating subsidiary that is unionized. Murray Energy Corporation produces approximately 30 million tons of bituminous co ...

Coal Mining In Kentucky
Coal was discovered in Kentucky in 1750. Since the first commercial coal mine opened in 1820 coal has gained both economic importance and controversy regarding its environmental consequences. As of 2010 there were 442 operating coal mines in the state, and as of 2017 there were fewer than 4,000 underground coalminers. History Just two years after the first coal was discovered in the United States in 1750 explorer Thomas Walker discovered coal in what would become Kentucky and used it to heat his camp fire. Although his discovery came in the Eastern Coalfield it would be another 150 years before commercial coal production occurred there. In 1820 the first commercial coal mine in Kentucky opened in the Western Coalfield in Muhlenberg County. In its first year the mine produced 328 tons of coal. By 1843 the state produced 100,000 tons of coal, and by 1879 the state produced one million tons of coal, all coming from the Western Coalfield. In 1900 the first commercial coal mine was o ...

Coal Mining In Wyoming
Coal mining in Wyoming has long been a significant part of the state's economy. Wyoming has been the largest producer of coal in the United States since 1986, and in 2018, coal mines employed approximately 1% of the state’s population. In 2013, there were 17 active coal mines in Wyoming, which produced 388 million short tons, 39 percent of all the coal mined in the US, and more than three times the production of second-place West Virginia. Market forces, including the low price of natural gas from the Shale gas in the United States, fracking boom—coal's main competition—contributed to the steep drop in coal production in the 2000s as electricity generation switched from coal to gas. History In 1868, the Union Pacific Railroad opened the first coal mine in Carbon County, Wyoming, Carbon County, and the county was named for its extensive coal deposits. In 2011 Wyoming's coal mines employed 7,000 people; a high was reached in 1981 when 38,500 Wyomingites were recorded as being ...

Illinois Basin
The Illinois Basin is a Paleozoic depositional and structural basin in the United States, centered in and underlying most of the state of Illinois, and extending into southwestern Indiana and western Kentucky. The basin is elongate, extending approximately northwest-southeast, and southwest-northeast. Boundaries and sedimentary rocks The basin is bordered on the northeast by the Kankakee Arch, on the southeast by the Cincinnati Arch, on the south by the Pascola Arch, on the southwest by the Ozark Dome, on the northwest by the Mississippi River Arch, and on the north by the Wisconsin Arch. The New Madrid Seismic Zone and the Wabash Valley Seismic Zone intersect the southern portion of the basin. The major structural features within the basin include the La Salle anticlinal belt, the DuQuoin monocline, the Cottage Grove fault system, and the Fairfield Basin. At its center beneath southern Illinois, the basin contains a thickness of about 15,000 feet of Cambrian throug ...

Appalachian Basin
The geology of the Appalachians dates back to more than 480 million years ago. A look at rocks exposed in today's Appalachian Mountains reveals elongate belts of folded and thrust faulted marine sedimentary rocks, volcanic rocks and slivers of ancient ocean floor – strong evidence that these rocks were deformed during plate collision. The birth of the Appalachian ranges marks the first of several mountain building plate collisions that culminated in the construction of the supercontinent Pangaea with the Appalachians and neighboring Anti-Atlas mountains (now in Morocco) near the center. These mountain ranges likely once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded. Geological history Paleozoic Era During the earliest part of the Paleozoic Era, the continent that would later become North America straddled the equator. The Appalachian region was a passive plate margin, not unlike today's Atlantic Coastal Plain Provin ...

Powder River Basin
The Powder River Basin is a geologic structural basin in southeast Montana and northeast Wyoming, about east to west and north to south, known for its extensive coal reserves. The former hunting grounds of the Oglala Lakota, the area is very sparsely populated and is known for its rolling grasslands and semiarid climate. The basin is both a topographic drainage and geologic structural basin, drained by the Powder River, Cheyenne River, Tongue River, Bighorn River, Little Missouri River, Platte River, and their tributaries. The major cities in the area include Gillette and Sheridan, Wyoming and Miles City, Montana. In 2007, the region produced 436 million short tons (396 million tonnes) of coal, more than twice the production of second-place West Virginia, and more than the entire Appalachian region. The Powder River Basin is the largest coal-producing region in the United States. The region includes the Black Thunder Coal Mine, the most productive in the United States, ...

Top 5 Coal States
A spinning top, or simply a top, is a toy with a squat body and a sharp point at the bottom, designed to be rotation, spun on its vertical Axis of rotation, axis, balancing on the tip due to the gyroscopic effect. Once set in motion, a top will usually precession, wobble for a few seconds, spin upright for a while, then start to wobble again with increasing amplitude as it loses energy, and finally tip over and roll on its side. Tops exist in many variations and materials, chiefly wood, metal, and plastic, often with a metal tip. They may be set in motion by twirling a handle with the fingers, by pulling a rope coiled around the body, or by means of a built-in auger (spiral plunger). Such toys have been used since Classical antiquity, antiquity in solitary or competitive games, where each player tries to keep one's top spinning for as long as possible, or achieve some other goal. Some tops have faceted bodies with symbols or inscriptions, and are used like dice to inject random ...

Metric Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a International System of Units#Non-SI units accepted for use with SI, non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the ton, non-metric units of the short ton (United States customary units), and the long ton (Imperial units, British imperial units). It is equivalent to approximately 2204.6 international avoirdupois pound, pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The International_Bureau_of_Weights_and_Measures, BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6

Short Ton
The short ton (symbol tn) is a measurement unit equal to . It is commonly used in the United States, where it is known simply as a ton, although the term is ambiguous, the single word being variously used for short, long, and metric ton. The various tons are defined as units of mass.Butcher, Crown and Gentry, NIST Special Publication 1038, The International System of Units (SI) – Conversion Factors for General Use, 2006 They are sometimes used as units of weight, the force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts a weight at one standard gravity of 2,000 pound-force (lbf). United States In the United States, a short ton is usually known simply as a "ton", without distinguishing it from the tonne (), known there as the "metric ton", or the long ton also known as the "imperial ton" (). There are, however, some U.S. applications where unspecified ''tons'' normally mean long tons (for example, naval ships) or metric tons (world grain ...
