How is coal mined? Read Full Story: http://www.spoonfeeding.in/2013/02/how-is-coal-mined-what-is-surface.html Mining is the process of removing coal from the ground. There are two types of mining: underground mining and surface mining. When the coal seam is fewer than 125 feet under the surface, it is mined by surface mining. Coal that is deeper than 125 feet is removed from the ground by underground mining. Underground mining is used when the coal seam lies deep in the earth. In an underground mine only some of the coal is removed. The coal that remains helps support the mine roof. Underground mines look like a system of tunnels. The tunnels are used for traveling throughout the mine, moving coal from place to place and allowing air to circulate in the mine. The coal that is mined is put on conveyor belts. The conveyor belts take the coal to the surface. There are three types of underground mines: slope, drift, and shaft. When the coal seam is close to the surface but too deep to use surface mining, a slope mine can be built. In a slope mine a tunnel slants down from the surface to the coal seam. A drift mine is built when the coal seam lies in the side of a hill or mountain. Drift mines may also be built in a surface mine that has become too deep. There are many drift mines in the eastern United States. The most common type of mine in Illinois is the shaft mine. These mines may be 125 to 1,000 feet deep. A large hole, or shaft, is drilled down into the ground until it reaches the coal seam.

Centralia, Pennsylvania was nearly entirely evacuated following a coal mine fire, burning beneath the town since 1962. Centralia’s fire started in 1962, when residents turned an old strip mine into a dump, and setting the rubbish alight. The fire spread through an unsealed opening to the underground coal mines, igniting a seam of coal, and the fire has been burning to this day. In 1992, Pennsylvania condemned the town and claimed it under eminent domain in an attempt for force the remaining residents out. Some sued, and were allowed to stay. A section of State Route 61 was abandoned after it began to buckle and crumble from the underground fire. The fire stretches 12km, and burns underneath an area of 15 square kilometres, 300 feet below ground, authorities say the fire could burn for another 250 years. The town now mostly attracts tourists who visit an abandoned highway, where many profanities and obscene pictures are spray painted onto it, over time the highway has earned the nickname Graffiti Highway. Centralia is rumored to have inspired Silent Hill.

South Africa's TauTona mine, real life alchemy, and Halicephalobus Mephisto. Footage from the 2012 documentary, "Down to the Earth's Core". We have travelled into space and looked deep into the universe's depths, but the world beneath our feet remains unexplored and unseen. Now, that's about to change. For the first time in one epic unbroken shot, we embark on an impossible mission - using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself. It's a journey fraught with danger. One thousand feet down we find ourselves inside one of the planet's most volatile places - the San Andreas Fault. Caught between two huge rock slabs, we watch as stress builds and then releases. It unleashes an earthquake and blasts us on towards rivers of molten rock, explosive volcanoes, tears in the Earth's crust and giant tornadoes of liquid metal. But for every danger, there are wonders beyond imagination. Four hundred feet below the surface, a three hundred million year old fossilized forest, with every leaf and every piece of bark perfectly preserved. At one thousand feet down we enter a cave of giant crystals, glistening in deadly 122 degree heat. More than two miles underground we find buried treasure - gold and gems. Deeper still there are valuable resources - salt, oil, coal and iron. And over one hundred miles down we see the sparkling beauty of diamonds. As we descend we piece together our planet's extraordinary story. We rewind time to discover how prehistoric forests became modern-day fuel. 1700 feet down a layer of rock reveals the extraordinary story of the dinosaurs' cataclysmic death. We watch stalactites form and gold grow before our eyes. The deeper we travel into the underworld the more we understand our world above the surface. A bigger picture takes shape - a cycle of destruction and creation, driven by the core that sustains our dynamic planet and makes the Earth the only planet with life in a seemingly lifeless universe. Until, finally, three thousand miles down, we reach the core. Inside it lie the secrets of life as we know it - the magnetic force field that protects life on Earth from the sun's deadly rays, the ancient heat source that keeps our planet alive. Down to the Earth's Core brings the latest science together with breathtaking computer generated imagery. The result is an unmissable journey into an extraordinary world - full of dangers, wonders and secrets. And it's all down there, beneath our feet, right now waiting to be discovered.

From the worlds largest gold mine found on the top of a mountain to the largest diamond mine in the world here are the most massive mines in the world! Subscribe to American EYE! 5.. Asbestos Mine, Canada Also known as the Jeffrey Mine, it’s located in Asbestos, Quebec and it was in operation until 2012. It’s a whopping 2 kilometers wide and 370 meters deep! Check out this thing on google maps and you can tell how completely massive this thing is! It’s the by far the largest asbestos mine in the world. For a long period of time, people would use this mineral to put into their walls and keep their homes from catching on fire! But recently there’s been a link with asbestos and a disease called mesothelioma, which is a lung condition. This is a toxic substance that people should avoid, so obviously this large mine went out of business. The lake at the bottom might look like an inviting blue, but you can bet your bottom dollar, it’s highly toxic! The small town that grew with the thriving asbestos industry feels like they’ve kind of lost their identity once the mine was forced to close, but people do still live there. 4. Mcarthur River Uranium Mine In case you were wondering which mine produces the most uranium in the world, that would be of course the Mcarthur River uranium mine in Saskatchewan Canada. This huge deposit was found in 1988 and finally a mining operation took place in 1997, when it began producing what’s known as Yellowcake. It’s not the kind of yellow cake you’d eat with your grandparents. This stuff has a horrific odor and basically what it is, is concentrated uranium powder which can then be used for powering nuclear reactors. We imagine this powdery substance is quite difficult to get ahold of. There aren’t a ton of photos of this place but, it does produce about 13 percent of the global uranium production across the globe. 3. Diavik Diamond Mine In case you thought it was Africa who had all the massive diamond mines, think again! The Diavik Diamond mine, found in the the northwest territories of Canada is one of the largest producers of diamonds in the Northern hemisphere and this place is pretty crazy! They annually produce 7 million carats of diamonds each year and you better believe it’s not easy to get here. The Diavik mine is found north of the arctic circle and it’s definitely cold! This photo here shows the subarctic landscapes that surround the diamond mine. You thought getting to work in the morning was tough for you? Imagine trying to get to work here! Just recently in 2015, this diamond produced what was known as the Diavik Foxfire 187.7 which is one of the largest rough gem quality diamonds ever produced. 2. Siberian Diamond Mine Also known as the Mirny Mine, The USSR began searching for ways to make to make themselves a more economical stable and independent union. In 1955 the Soviets discovered large diamond deposits at this site in the far away lands of Siberia and many people got to work very quickly in order to help bring wealth to the union. After about 20 years of operations, they finally decided that At one point this mine produced 10 million carats of diamonds a year and reaches a max depth of 524 meters or around 1700 feet making it the 2nd largest excavated hole in the world. The mine is so deep, airspace is closed over the hole due to helicopter crashes caused from the downward flow of air. The construction of this in the frigid conditions of Siberia must have been grueling and downright cruel. Sources state that the machinery used at this mine had to be covered at night or it would freeze Are the diamonds worth freezing to death?! It’s unoperational today but Some claim that there’s still a bunch of diamonds in this mine and the whole thing could be worth about 12 Billion dollars. It’s possible that controlling this diamond is mine is crucial to controlling the price of diamonds across the world. Bingham Copper Mine The bingham copper mine located near Salt Lake City Utah is home to the biggest pit in the world and it’s been in operation since 1903. It’s about 2.5 miles wide and if it were a stadium, it would be able to fit an estimated 9.5 million people. It keeps getting bigger and bigger too! Diligent workers can move about 250,000 tons of rock each day and it’s even become a tourist attraction in recent years before a massive landslide took place. Some claim that this was the biggest non volcanic landslide to take place in North American modern history. This photo we see here shows you the aftermath of this massive landslide and Bingham Copper mine and it makes you wonder how safe some of the conditions at these mines truly are. The landslides were so massive, that they actually triggered a few small earthquakes! Experts estimated that 165 tons of earth slide down from the top of the mine all the way to the bottom.

NOTE: Although this video shows an up-close look at the blasting process, NEVER go near an active surface mine or blast site without Federal training and permission. FYI, the white bags are Emulsified Ammonium Nitrate. The read cap is TNT and the silver rod that is connected to it by the yellow wire is the blasting cap, it's what ignites the shot. The white pebbles that are emptied into the blast holes by the powder trucks are the main explosive- "ANFO" or Ammonium Nitrate, which is a mixture of fertilizer and diesel fuel. Once the holes are filled with explosives, rock fines or "stemming" is pushed back in the holes and packed down to keep the explosives under pressure. After all the holes are loaded and rigged up, it's time for the fireworks! And remember kids, don't try this at home! Want to see more Blasting?

While coming back down from some mines way up north, Paul and I stopped at the abandoned Admiral Aaron Ward Mine and walked down its 4100-foot inclined entry tunnel into the subterranean workings. Once we reached the bottom, we found wide tunnels branching off in all directions in this former silver, copper, and zinc mine. During our five-hour exploration, we found one stope that was unbelievably huge and utterly mind-blowing! We also found deep, flooded areas and bottomless shafts. Various colorful mineral growths and crystal growths appear throughout the mine's tunnels, too. The miners' workshop was still full of spare parts, tools, and other artifacts. Another interesting find was the miners' refuge chamber. A freshwater spring deep in the mine provided us with some of the cleanest and best-tasting water I've ever drank! After five hours of exploring, we decided to call it quits and began the long, arduous hike back up the 4100-foot, inclined entry tunnel to the surface.

Highwall Miners are the most effective and cheapest method of producting coal -- essentially these remote-controlled continuous miners. These can advance much further into the highwall than augers (up to 600 feet), and machines are available that can mine in as far as 1,600 ft, achieving production levels (in Appalachia) of 300,000 tons a month -- crew of 3 or 4 folk, and averages 30 -- 40 tons per man-hour. --- The federal Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM) does not regulated Highwall Miner operations. Until 2002, virtually all higwall mining operations were regulated as surface mining operations (auger mining) rather than as underground operations. . . . The auger mining rule indicates that OSM will consider rulemaking if it becomes necessary. . . . (The OSM Assistant Director for Program Support (AD-PS) presented an option paper to Director Wahlquist in April of 2007. In May of 2007, AD-PS was informed that OSM would not take action on the topic and treatment of Highwall Mining Operations would remain status quo [ -- up to the individual states to determine]. === Terex System video: http://www.youtube.com/watch?v=tUiK0TokQsM Addcarsystem video: http://www.addcarsystems.com/multimedia/high%20wall%20mining101.wmv Fairchild Miner video: http://www.youtube.com/watch?v=Q_tMLO_weuA http://oilprice.com/Energy/Coal/Coal-Mining-and-the-Highwall-Method.html This video was posted here: http://www.youtube.com/watch?v=QYm5haG21ks

Underground coal mine :- Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping point (limited by geology, ventilation, or economics), a supplementary version of room and pillar mining, termed second mining or retreat mining, is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section. Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to a large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area.

Here are 11 of the most unusual findings deep in the earth like ancient and time primate fossils or trapped toads alive in rocks!! Subscribe to Talltanic http://goo.gl/wgfvrr # 7 Toads found in Rock One strange phenomena that still doesn’t have an explanation are toads that find themselves entombed deep into stone and continue to live. For years quarriers and miners have discovered to their surprise, live toads inside of the rocks they crack open. In some cases the toads are found 5, 10, and even 20 feet deep inside of rock. In all cases, they have no visible way in or out and yet in all cases they are all still alive. This bizarre phenomena is often called “toad in the hole”. No one knows how these toads find themselves in the rock, or how they survive without any water, food, or air. # 6 Ghost Miners in Mponeng The world’s deepest gold mine called the Mponeng Mine located in South Africa runs so far into the ground with so many winding tunnels that it’s almost like a dark underground city. The expansive, dark, and hot mine is almost impossible to completely keep watch over so every once in awhile an illegal squatter will be discovered. Mponeng squatters are called “ghost miners” and will find empty caverns to make their home in, illegally mine gold to sell above ground, and will even meet with prostitutes in the mines. # 5 The Bold Travelers of Mponeng - Desulforudis audaxviator In the world’s deepest gold mine, a new species of bacterium was discovered called Desulforudis audaxviator. Audaxviator translates to “bold traveller” which refers to the fact that the bacteria was found 2 miles below the surface of the Earth and is the only organism in its ecosystem. The strange bacteria has evolved to live without sunshine or oxygen. Instead, it lives off of hydrogen and sulfide as food, which come from the breakdown of radioactive elements. Basically, it’s a nuclear waste eating bacteria. It’s the only one of its kind and have amazed scientists with its complete solitude underground. # 4 Giant Roach Fossil Found in Ohio Coal Mine Geologists were combing through an old coal mine in an area known for its plant fossils when they discovered an extremely rare fossil. It was a giant roach fossil - about 4 inches long and twice as big as most modern American roaches. The fossil is rare because it’s completely in tact, while most insect fossils are only partial imprints. Fossils in the cave also preserved some of the smallest cockroach fossils ever found and their color patterns. Inside the coal mine, even more rare insect fossils were found including a rare ancient arachnid and a 60 inch long and 12 inch wide centipede. The chemistry of this coal mine in Ohio somehow preserved these insects with extreme detail that is not seen anywhere else. # 3 Dead Body found in Ghost Town Mine Hobby adventurers had the scare of their life when they were exploring an abandoned ghost town called Whroo in Victoria, Australia. The two were in the ghost town’s abandoned mine when they found a dead body covered in plastic and shoved into a deeper hole inside. The victim was a 50 year old man in a Neil Young shirt and the perpetrators were later found to be a 26 year old man and 30 year old woman. The details on this case are scarce, but it has all the makings of a really good CSI episode. # 2 Four Square Miles of Carboniferous Forest Discovered The fossils of almost an entire forest from the Carboniferous period was uncovered in the ceiling of two adjacent coal mines in Illinois. This discovery is the largest single-period fossil discovery in recorded history. Archaeologists delved into the 250 feet deep mine to explore and record the fossils. There were upwards of 200 specimens of detailed shrubs, trees, flowers, and even insects. # 1 Tiny, Strange Primate Fossil In the Krabi coal mine of Thailand, archaeologists uncovered a new species of a teacup sized primate. They found mandibles that belong to the pea-sized primates called Krabia minuta. Krabia minuta were native to Asia and are the ancestors to all monkeys, apes, and humans. They were impressively able to make it to Africa despite being separated from a body of water at the time that was bigger than the Mediterrenean sea. This bizarre find is very important for archaeologists, because it indicates a period of extreme evolution of primates in the area and will continue to yield more discoveries in years to come.

Early Mining The southeastern part of Cape Breton Island is home to the Sydney Coal Field, an extensive underground coal seam extending at an angle from the shore beneath the seafloor of the Cabot Strait. This large deposit of high-sulphur coal was first extracted by French soldiers from Fortress Louisbourg in 1720 at nearby Port Morien. A major coal industry developed during the 19th century, becoming the largest energy project in British North America at its height of production. The largest integrated steel mill in the British Commonwealth was constructed on Sydney Harbor in 1901. The coal and steel industries went into decline following World War II and never fully recovered. They were nationalized by the federal and provincial governments during the late 1960s with the intention of closing them by the 1980s, however production increased in the 1970s as a result of rising world oil and steel prices. By the 1990s, environmental degradation (see Sydney Tar Ponds) and economic ruin was facing the industrial Cape Breton region. The steel mill and last coal mine were closed in 2001 and the area has been struggling to adapt. While the urban area of eastern Cape Breton County influenced by the coal and steel industries came to be referred to as "Industrial Cape Breton", many rural communities in the rest of Cape Breton Island have been relatively stable economically, largely due to the mix of fishing, forestry, small-scale agriculture, and a growing tourism industry as a result of the spectacular scenery found throughout the island. In 1914 the SCOTIA steel mill was closed and in 1920 both DOMCO/DISCO and SCOTIA were merged into a new company named British Empire Steel and Coal Company (BESCO). The copyright of this section might be in question and is likely from UMWA material. IN MARCH OF 1925, Cape Breton coal miners were receiving $3.65 in daily wages and had been working part-time for more than three years. They burned company coal to heat company houses illuminated by company electricity. Their families drank company water, were indebted to the company "Pluck Me" store and were financially destitute as evidenced by the company "Bob Tailed Sheet". Local clergy spoke of children clothed in flour sacks and dying of starvation from the infamous "four cent meal". The miners had fought continuously since 1909 for decent working conditions, an eight hour day and a living wage. The British Empire Steel Corporation (BESCO) was controlled by President Roy M. Wolvin and Vice-President J.E. McClurg who defended these conditions by frankly stating, DEVCO and SYSCO On July 7, 1967 the Cape Breton Development Corporation (DEVCO) was created and on March 30, 1968 all DOSCO mines were expropriated for $12 million by DEVCO. At the same time, the provincial government formed the Sydney Steel Corporation (SYSCO) and took over DOSCO's steel mill, with the aim being to gradually control the shut down of this industry. DEVCO brought in new tourism initiatives throughout Cape Breton Island and funded various community economic development programs, however politics and other factors such as the 1973 oil crisis brought about by the OPEC embargo following the Yom Kippur War saw demand for coal increase dramatically, particularly for electrical generation. The federal government reversed course and chose to expand, rather than retract, the production of coal and opened new mines and modernized its DOSCO-inherited properties to serve new electrical generating stations. During the 1980s the provincial government also modernized the steel mill, however both coal and steel encountered production and financial difficulties in the 1990s and DEVCO and SYSCO both decommissioned their operations by the turn of the century or shortly thereafter. The last underground coal mine on Cape Breton Island closed in November 2001. From Wikipedia, the free encyclopedia.

What is UNDERGROUND MINE VENTILATION? What does UNDERGROUND MINE VENTILATION mean? UNDERGROUND MINE VENTILATION meaning - UNDERGROUND MINE VENTILATION definition - UNDERGROUND MINE VENTILATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NOx, SO2, methane, CO2 and CO) and to regulate temperature. The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. The largest component of the operating cost for mine ventilation is electricity to power the ventilation fans, which may account for one third of a typical underground mine's entire electrical power cost. Flow-through ventilation is the main ventilation circuit for the mine. Air enters the mine from surface via a shaft, ventilation raise or adit. The air is distributed through the mine via internal ventilation raises and ramps, and flows are controlled by regulators and permanently mounted ventilation fans. An auxiliary ventilation system takes air from the flow-through system and distributes it to the mine workings via temporarily mounted ventilation fans, venturies and disposable fabric or steel ducting. Auxiliary fan and duct systems may be either forcing systems, where fresh air is pushed into mine headings, or exhausting systems that draw out contaminated air. Sufficient volume of air is required for proper ventilation. A bulk of electric power is required for driving fans. By installing variable speed control air quantity can be optimized hence the power. at every place in the mine where persons are required to work or pass, the air does not contain less than 19% of oxygen or more than 0.5% of carbon dioxide or any noxious gas in quantity likely to affect the health of any person; the percentage of inflammable gas does not exceed 0.75% in the general body of the return air of any ventilating district and 1.25% in any place in the mine. The volume (expressed in cubic feet per minute or cubic meters per second) of air required to ventilate an underground mine is determined by mining engineers based on a wide variety of parameters. In most countries minimum requirements are outlined by law, regulation or standards. However, in some developing countries the mandated ventilation requirement may be insufficient, and the mining company may have to increase the ventilation flow, in particular where ventilation may be required to cool the ambient temperature in a deep hot mine, however auto-compression must also be taken into account. as per CMR 130-2-(i) in every ventilating district, not less than six cubic metres per minute of air per personemployed in the district on the largest shift or not less than 2.5 cubic metres per minute of air per daily tonne output whichever is larger, passes along the last ventilation connection in the district which means the inbye-most gallery in the district along which the air passes. In temperate climates ventilation air may need to be heated during winter months. This will make the working environment more hospitable for miners, and prevent freezing of workings, in particular water pipes. In Arctic mines where the mining horizon is above the permafrost heating may not take place to prevent melting the permafrost. "Cold mines" such as Raglan Mine and Nanisivik Mine are designed to operate below 0°C. the wet bulb temperature in any working place does not exceed 33.5°C and where the wet bulb temperature exceeds 30.5°C arrangements are made to ventilate the same with a current of air moving at a speed of not less than one metre per second.

'Underground mining scenes... Sequence shows miners leaving work, washing up and going home to greet families.' Reupload of a previously uploaded film with improved video & sound. Public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Anthracite Anthracite... is a hard, compact variety of mineral coal that has a high luster. 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%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. 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 majority of global production; other producers are Russia, Ukraine, North Korea, Vietnam, the UK, Australia and the US. Total production in 2010 was 670 million tons... Other terms which refer to anthracite are black coal, hard coal, stone coal... blind coal... Kilkenny coal... crow coal... and black diamond. 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. Legend has it that Allen fell asleep at the base of Broad Mountain and woke to the sight of a large fire because his campfire had ignited an outcropping of anthracite coal. By 1795, an anthracite-fired iron furnace had been built on the Schuylkill River. Anthracite was first experimentally burned as a residential heating fuel in the US on 11 February 1808, by Judge Jesse Fell in Wilkes-Barre, Pennsylvania, on an open grate in a fireplace. Anthracite differs from wood in that it needs a draft from the bottom, and Judge Fell proved with his grate design that it was a viable heating fuel. 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, until it was supplanted first by oil burning systems and more recently by natural gas systems... China today mines by far the largest share of global anthracite production, accounting for more than three-quarters of global output. Most Chinese production is of standard-grade anthracite, which is used in power generation. Increased demand in China has made that country into a net importer of the fuel, mostly from Vietnam, another major producer of anthracite for power generation, although increasing domestic consumption in Vietnam means that exports may be scaled back. Current U.S. anthracite production averages around 5 million tons per year. Of that, about 1.8 million tons were mined in the state of Pennsylvania...

Filmed by Keystone in 1911 for the LNWR ( London & North Western Railway ) who had their own full time film unit. The film was produced to feature both a typical Lancashire colliery served by the LNWR and also the women surface workers or Pit Brow Lasses who had been in the news after moves to legislate against their empoyment on the surface at collieries. More women surface workers were employed at Lancashire collieries than in any other coalfield. The colliery featured was Alexandra Colliery of Wigan Coal & Iron Co Ltd. Shafts were sunk at the colliery from 1856 in an ancient mining district, records going back to the 14th century. The shaft eventually reached 772 yards and the Arley seam. The famous Haigh Cannel seam was also accessed. The colliery closed in June 1955.

Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century)is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction. Since 1983 the world top coal producer has been China. Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide releases. There were no Bucket Wheel Excavators back then!
