Fully mechanized Longwall Coal Production

The goal of coal mining is to obtain coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a colliery. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyors, jacks and shearers. - H&T

Coal produces nearly half the electricity in the U.S., but the mercury, sulfur dioxide and carbon dioxide it emits also make it one of the most controversial energy sources. New EPA regulations and a national Sierra Club campaign have added to rising anti-coal sentiment. For many environmental activists, coal represents an old, dirty source of power, but for coal-mining communities around the country, the story is different.

In November 2009, Eco-Justice Collaborative (www.ecojusticecollaborative.org) traveled with representatives of Topless America and the Sierra Club to central Illinois to take a first-hand look at longwall mining. This highly-mechanized form of mining includes planned subsidence, causing land to drop from 4 to 6 feet. It is occurring under some of the best farmland in the world, trading prime farmland for cheap coal. As land subsides, foundations crack and septic systems and wells are affected. Residents often leave their homes and farms, depopulating and destroying what used to be cohesive communities, rather than negotiate repairs with mining companies. Longwall mining is Illinois form of mountaintop removal mining. As with mountaintop removal mining, toxic chemicals are used to process coal. Evidence suggests that these chemicals are leaching into ground water and water supplies at selected locations. This video highlights impacts in central Illinois Macoupin County, and takes an initial look at the proposed Deer Run Mine in Montgomery County which, if constructed as planned, will be the largest coal mine in the U.S. To learn more, contact Pam or Lan Richart at [email protected] or Citizens Against Longwall Mining: [email protected]

Cat® Shearers are not only cutting coal, but other soft minerals too. Here's the Cat EL3000 Shearer operating in a trona mine near Green River, Wyoming. Learn more about Cat Shearers: https://mining.cat.com/shearers Trona is a sodium carbonate compound that is processed into soda ash or bicarbonate of soda. Wyoming has the world's largest deposit of trona, supplying about 90% of the United States' soda ash. Glassmaking consumes about half of the soda ash, followed by the chemical industry, which uses about a quarter of the output. Other uses include soap, paper manufacturing, and water treatment. All baking soda also comes from soda ash. (Source: Wyoming Mining Association)

McClure #1 Mine about 30 years ago. One of the deepest, largest, and most dangerous mines in the country.Known as a 'Hot" mine- This mine released over 3 million cubic yards of explosive methane gas per day. It had at least 1 fatality per year for every year it was open. In 1983 it made national news when it exploded and 7 were killed including the first woman killed in a mining disaster. What you are seeing in this footage is a massive "Long-wall" machine which sheers off a shelf of coal sometimes up to 2,000 feet long at a time. The Hydraulic Jacks or 'Shields" which are constantly adjusted support the roof of this part of the mine as the machine advances. Unlike a traditional "pillar' mine, in which tunnels are cut in a honeycomb fashion, by a 'continuous miner, a longwall has cutting wheels on both ends and goes back and forth and removes football fields in a single shift. Another difference id the roof in the area already mined (Gob) is allowed to collapse, which causes subsidence of everything above ground-streams disappear and divert underground, foundations of buildings collapse, cracks and sinkholes swallow farm animals and wildlife. My cousin gave me this rare, never-before seen footage ten years ago, hoping I could use it to show people the brutality of coal mining-underground, particularly Long-Wall mines is not much better than blasting off mountaintops. It still produces acid mine runoff, in addition to surface subsidence, it is extremely dangerous-the workers are wearing no breathing protection, nor ear protection, they are surrounded by dangers of electrocution, rock falls, explosions, being crushed to death, being ground up like meat, and a dozen other ways to die in a mine...The Upper Big Branch Mine explosion (2010) was a Long-Wall mine and the deadliest since this mine blew in 1983. All forms of American Coal Mining are deadly, destructive, and unacceptable in the 21st century to have an average of 180 fatalities in our mines per year! In Germany they have ZERO fatalities, and almost zero impact on property and the environment-Makes you wonder what the difference is between here and there??? I included it in a documentary film in 2007, which was submitted to several regional groups, along with a paper that received an invite to a conference at a University in the Carolinas...I suppose it got shelved and forgotten. Well here it is on YouTube for all the world to see.

Joy Mining Machinery releases a new version of its most popular video "Pioneering Underground Mining". You can request a free copy of this video by contacting [email protected] and provide your name and mailing address and if you want the copy in DVD or Blu-ray format. It was first produced in 2001 to support a request by our US Midwest sales region to help a customer explain the difference between room and pillar and longwall mining to finance people. It quickly became the most widely distributed video in our library being used by universities, schools, shown to community groups, etc. The program was updated to show new products and includes all new HD video and animations.

Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery. In Australia, "colliery" generally refers to an underground coal mine. In the United States "colliery" has historically been used to describe a coal mine operation, but the word today is not commonly used. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts, to large open cut and long wall mines. Mining at this scale requires the use of draglines, trucks, conveyors, jacks and shearers The American share of world coal production remained steady at about 20 percent from 1980 to 2005, at about 1 billion short tons per year. The United States was ranked as the 2nd coal producing country in the world in 2010, and possesses the largest coal reserves in the world. In 2008 then-President George W. Bush stated that coal was the most reliable source of electricity.[61] However, in 2011 President Barack Obama said that the US should rely more on "clean" sources of energy that emit lower or no carbon dioxide pollution.[62] As of 2013, while domestic coal consumption for electric power was being displaced by natural gas, exports were increasing. US coal production increasingly comes from strip mines in the western United States, such as from the Powder River Basin in Wyoming and Montana.[63] Coal has come under continued price pressure from natural gas and renewable energy sources, which has resulted in a rapid decline of coal in the U.S. and several notable bankruptcies including Peabody Energy. On April 13, 2016 it reported, its revenue tumbled 17 percent as coal price fell and lost 2 billion dollars on the previous year.[64] It then filed Chapter 11 bankruptcy on April 13, 2016.[64] The Harvard Business Review discussed retraining coal workers for solar photovoltaic employment because of the rapid rise in U.S. solar jobs.[65] A recent study indicated that this was technically possible and would account for only 5% of the industrial revenue from a single year to provide coal workers with job security in the energy industry as whole. https://en.wikipedia.org/wiki/Coal_mining

It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92.1% and 98%... Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, and high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. China accounts for the lion's share of production; other producers are Russia, Ukraine, North Korea, Vietnam, the UK, Australia and the US. Total production in 2010 was 670 million tons... Terminology Other terms which refer to anthracite are black coal, hard coal, stone coal (not to be confused with the German Steinkohle or Dutch steenkool which are broader terms meaning all varieties of coal of a stonelike hardness and appearance, like bituminous coal and often anthracite as well, as opposed to lignite, which is softer), blind coal (in Scotland), Kilkenny coal (in Ireland), crow coal (or craw coal from its shiny black appearance), and black diamond. "Blue Coal" is the term for a once-popular and trademarked brand... Anthracite is similar in appearance to the mineraloid jet and is sometimes used as a jet imitation. Anthracite differs from ordinary bituminous coal by its greater hardness, its higher relative density of 1.3--1.4, and lustre, which is often semi-metallic with a mildly brown reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter... The moisture content of fresh-mined anthracite generally is less than 15 percent. The heat content of anthracite ranges from 22 to 28 million Btu per short ton (26 to 33 MJ/kg) on a moist, mineral-matter-free basis... Anthracite may be considered to be a transition stage between ordinary bituminous and graphite, produced by the more or less complete elimination of the volatile constituents of the former... History of mining and use In southwest Wales, anthracite has been burned as a domestic fuel since at least medieval times. It was mined near Saundersfoot. In the United States, anthracite coal history began in 1790 in Pottsville, Pennsylvania, with the discovery of coal made by the hunter Necho Allen in what is now known as the Coal Region... By 1795, an anthracite-fired iron furnace had been built on the Schuylkill River... In spring 1808, John and Abijah Smith shipped the first commercially mined load of anthracite down the Susquehanna River from Plymouth, Pennsylvania, marking the birth of commercial anthracite mining in the United States. From that first mine, production rose to an all-time high of over 100 million tons in 1917. From the late 19th century until the 1950s, anthracite was the most popular fuel for heating homes and other buildings in the northern United States... Many large public buildings, such as schools, were heated with anthracite-burning furnaces through the 1980s... http://en.wikipedia.org/wiki/Coal_mining The goal of coal mining is to obtain coal from the ground.
