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

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.

HOT can help you to maximize ore reserve value basis on our operating expertise We have years of underground mine engineering and operating experience and across multiple commodities using all common mining methods. Especially, we have many successful design and operation experiences for underground coal mines those are thin coal seam, large dip angle, as well as many faultags. And most of these coal mines (thin coal seam) are designed and operated by longwall mining method (fully mechanized mining). The thin coal seam longwall method helps to satisfy the highest safety standard and more margins. ● Large dip angle, thin coal seam longwall（dip angle range: 35°-55°） ● Thin coal seam, very thin coal seam longwall（Thinnest seam range: 0.8m ~ 1.3m）

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.

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.

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

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]

Caterpillar has developed the Cat® GH800B Longwall Plow System, designed for mining very low coal seams at high rates. Building on the attributes of the proven GH1600 Plow System, the Caterpillar longwall team in Lünen, Germany, worked with the German Ibbenbüren mine to design and construct a system for mining an anthracite seam averaging only 0.85 meters (33.5 inches) thick. The result is the GH800B Plow and associated longwall system.
