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.

How Coal Is Mined and Refined - Top Coal Mining Spots in the World - Documentaries. Welcome to DOCUMENTARIES - home of the best documentary movies and documentary films. Coal mining is the process of extracting 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 Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the above-ground structures the pit head. In Australia, "colliery" generally refers to an underground coal mine. In the United States, "colliery" has been used to describe a coal mine operation but nowadays the word is not commonly used. Coal mining has had many developments over the recent years, from the early days of men tunnelling, 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, hydraulic jacks and shearers.

Underground coal mine by Indian minerology
 
09:29
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.[5] 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.

How Coal Mines Work: "Mining and Preparation of Anthracite Coal" circa 1934 Delaware & Lackawanna

'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...

The Principle of Longwall Top Coal Caving (LTCC)
 
03:58
Caterpillar has extensive experience in the design of roof supports for specific mining conditions. Cat Longwall Top Coal Caving (LTCC) roof supports allow mining of seams seams thicker than 6 meters (20 feet). Following a conventional cut with a shearer to about 3 m (9.8 ft) the roof supports move forward and allow the caving of the top coal behind the roof supports a second conveyor mounted gob-side. This special LTCC method enables increased coal reserve recovery for only an incremental additional cost. This animation shows how it works.

Coal Mining the Modern Way: Newcastle, 1957
 
02:27
A silent newsreel item from 1957 about mechanised coal mining procedures at the Awaba State Coal Mine, near Newcastle in New South Wales. The item opens with shots of miners going down into, and later leaving, the mine. We see older footage of miners underground using picks and shovels to break up the coal and load it onto carts. A pit pony takes the coal away. The newsreel contrasts this with the modern methods of cutting coal from the coalface using a machine. Two miners bore a hole in the coalface and set explosives. Coal is loaded into a truck using a mechanical loader and taken to storage bins by a locomotive. A conveyor belt takes the coal from the mine to the Crusher Shed where it is transported away by truck. Coal Mining the Modern Way, Newcastle, NSW, 1957. NFSA title: 128513

Hunting History: UNDERGROUND RIVER FOUND AT UKS BIGGEST COAL MINE!
 
18:15
We went out recently over Daw Mill Colliery one of the UKs largest coal producers before its closure to see whats now become of this once thriving site. we had a good explore above ground and then started below were we came across a pretty fast flowing underground river! Daw mill colliery history: Daw Mill was the largest mine and biggest producer of coal in its region, located just outside of a town called Nuneaton. It first opened in 1956 with the first shaft being sunk between 1956-1959 and the second sunk between 1969-1971. The mine was a natural extension of former collieries Kingsbury and dexter all of which mined in the five metre Warwickshire coal field known as the Warwickshire thick. After the denationalisation of the coal industry Daw Mill was brought by UKCoal and by 2008 nearly 700 people worked at the mine, it was also this year that Daw Mill produced over 3.25million tons of coal beating a 13 year old record for annual output. However as early as 2009 talks about Daw Mill future had begun with coal prices dropping each year and railway threats to business. In 2009 Daw Mill was rated the most technologically advanced and most productive mine in Europe. The colliery was situated on the Birmingham to nuneaton line just east of the former Shustoke railway station. In 1983 an inclined tunnel linking underground workings with the surface was completed. This drift mining enabled Daw Mill to increase its production capacity as it removed the often time-consuming process of winding coal up the shafts. On record 3 men have been killed at Daw Mill in mining accidents in 2006 and 2007. In 2011 UKCoal was fined 1.2million pounds for safety breaches. On 22nd February 2013 a major fire broke out in the mine 500 metres underground and was described as the worst underground blaze in Britain for 30 years, no one was injured however with the fire unable to be put out for months the damage left behind compared with profits each year was not justified and the mine never re-opened after the fire. Daw Mill was the last remaining colliery in the West Midlands, once operating 20 collieries. Most the the Daw Mill site has now been demolished and the remaining buildings in recent years have really taken a beating from vandals (even last year the remaining buildings were in pretty good shape) unfortunately id never taken my camera before so thought I would this time to film what remains. most of the shoots with the convyer belts are now filled completely with water and only one still has room to get down into, the house remains, power room, a couple of odd sheds and warehouses, and of course all the underground fun. This video will be in 2 parts so keep an eye out for the second part coming soon! if you could drop the page a subscribe and like the video that’ll be much appreciated cheers all!
