Fully mechanized Longwall Coal Production

PART 2 https://www.youtube.com/watch?v=JfY1IQyCEVk 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 is that 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; -the workers are wearing no breathing protection, no ear protection, they are surrounded by dangers of electrocution, rock falls, methane explosions, being crushed to death, being ground up like meat (should they accidentally touch the conveyor belt, as was one of the many deaths in this particular mine), 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 it is completely unacceptable in the 21st century to have an average of 180 fatalities in our mines per year! the only reason for this is corporate greed. There is a special place in hell for the likes of Don Blankenship (who was head of Pittson at the time this was filmed, and responsible for the brutality, and murder during the strike in 1991- he later became famous as the head of Massey presiding over the three most recent and deadliest mine explosions; in each case found guilty of hundreds of safety violations, unpaid fines, and was infamous for his union-busting and intimidation/blacklisting of workers which sought safety and better conditions-prior to his tenure the southern coalfield had been organized for 70 years-today there are less than half a dozen union mines in the tri-state region, all the union hospitals are closed, and black-lung is at an all time high!) God, have mercy on the few remaining miners in southwestern Virginia, eastern Kentucky, and southwestern West Virginia who work the Pocahontas #3 seam; the 'highest coal seam' (6-21 ft)in the country that runs from Pennsylvania to Alabama.....I can see why so many miners perfer "low coal' (3-5 ft)...as my cousin said, "..if a rock from the roof (as pictured in part 2) falls from 3 feet, it won't hurt you, but at six feet it will kill you." I included it in a documentary film in 2007, which was submitted to several regional groups, along with a scholarly paper on the history of mining in central appalachia that received several invites to a conferences at a Universities in the region...I suppose it got shelved and forgotten. Well here it is on YouTube for all the world to see.

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.

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.

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]

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.
