This video provides a basic description of the long-wall mining method for extracting coal underground. It includes an explanation of the different products/key components of a long-wall mining system (long-wall shearer, automated plow system, AFC face conveyor, line pans, CST drive system, roof supports, long-wall automation). CAT can support roof heights from 0.8 meters to 7.5 meters.

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 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.

Higher Productivity for the Long Run Coal panels and face lengths are increasing -- the average seam height is not. Maximizing productivity levels as the seam height diminishes requires the optimization of cutting power, haulage power, reliability, ease of maintenance and operator ergonomics. Enhanced safety features that address the challenges of mining lower seams also need to be provided. As the boundary conditions for longwall operations evolve Caterpillar continuously develops solutions that will safely maintain or boost your productivity. For low seam shearer applications the most compact Cat solution yet will be there to deliver the results you expect: the new Cat EL1000. This latest addition to the successful range of Cat longwall shearers will cover seam heights from 63 to 126 inches (1.6 to 3.2 meters).

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)

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.

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.

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

Today, Caterpillar is the market leader in the field of fully integrated and automated plow systems. Sophisticated Cat plow systems today operate fully automatically with drive powers of up to 2 x 800 kW and speeds of up to 3.6 m per second. Seam thicknesses between 0.6 and 2.3 meters (23.6 and 90.5 in) can be efficiently mined with this method. Plowing is the preferred longwall mining technique for seams below 1.8 m (71 in). The depth of cut is set via the electro-hydraulic support control system in connection with stroke sensors in the shifting rams of the roof support.

The longwall is a machine that has the ability to remove large volumes of coal single pass. The length of the pass can be 200 - 300m long. It consist of a few key elements, Chocks - support the roof of the longwall area, Shearer - cuts the coal through its rotating drums Armoured face conveyor (AFC) - directs the coal to the end of the pan line, where it is transported on conveyors to the surface.
