History of Coal Mining in Illinois Extracted from A Compilation of the Reports of the Mining Industry of Illinois from the Earliest Records to 1954 5 ; The Discovery of Coal The first reference to coal being found in North America appeared in an article published in Paris in 1672 by Nicholas Denys, appointed governor of Eastern Arcadia in 1637.

To become a surface miner apprentice you don't need any experience because once you pass the course you'll be authorized to work onsite with certified surface miners where you'll learn on the job training in the work that is done at a surface coal mining operation.
Mine operators for some time now have been increasingly turning to an alternative to conventional rip-and-stack or drill-and-blast coal mining: the use of surface miners.
Surface mining is accomplished by removing overburden from the coal seam and then removing the coal. Miners employed at surface mines operate draglines, shovels, bulldozers, front-end loaders, bucket wheel excavators and trucks. While safety issues at surface mines are different than in underground mines, there are still many safety concerns the union contract addresses.
Most of the surface coal mining in Missouri took place before the Federal Surface Mining Control and Reclamation Act of 1977, or SMCRA. This is the United States law that governs the activities of surface coal mining and reclamation throughout the country today. Surface coal mining in Missouri has significantly changed from earlier times.
Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining.
Early surface mining consisted of extracting coal that was exposed along a hillside, using picks and shovels (from Crowell, 1995, p. 18). Following the Great Depression of the 1930's, coal produc-

Many of these positions ...
The negative effects of coal mining cannot be disputed: Destruction of Landscapes and Habitats : Strip mining also known as surface mining, involves the stripping away .
Surface mining allows the removal of coal from the surface rather than through underground tunnels. It requires the stripping away of earth, rock, and vegetation (collectively known as overburden) from above the coal deposit, which can then be mined and trucked away.
Oklahoma Department of Mines (ODM) is the state agency responsible for ensuring the reclamation of land disturbed by mining operations. The Department regulates the production of coal .
Activities conducted on the surface of lands in connection with a surface coal mine or, subject to the requirements of § 45.1-243, surface operations and surface impacts incident to an underground coal mine, the products of which enter commerce or the operations of which directly or indirectly affect interstate commerce.
North American Coal offers high-efficiency, cost-effective contract mining solutions. Our goal is to partner with our customers to deliver success long-term success through integrated mining solutions that conserve critical habitats, reduce emissions and protect Native American Heritage.
The Non-Coal Review Branch of the Division of Mine Reclamation and Enforcement (DMRE) regulates and enforces the surface mining reclamation laws and regulations for non-coal mining sites in the state, which include limestone and dolomite, sand, gravel, clay, fluorspar, tar sands or rock asphalt, shale, surface effects of dredging river sand and ...
Coal mining is further divided into Bituminous coal underground mining, Bituminous coal and lignite surface mining, and Anthracite mining. Bituminous coal underground mining employs slightly more than half of all coal mining industry workers, but experiences a higher share of .
Surface Mining. Surface-mining methods include area, contour, mountaintop removal, and auger. Area mines are surface mines that remove shallow coal over a broad area of fairly flat land.
Coal mining is far and away the largest industrial consumer of explosives in the United States. According to government figures for 2005, more than 1.8 billion pounds of high explosives were used in West ia and Kentucky alone, primarily in surface-mining operations.
Surface mining permanently destroys the environment. It is a broad type of mining in which soil and rock over the mineral deposit are removed. It is a method used to mine coal near the surface .
Why surface miner is suitable, not the conventional mining system. Effect of utilization of surface miner on economics of mine. Effect of disposition of surface miner on the quality of coal.
.2.b. Contour mining is practiced in areas where it is uneconomical to remove all the overburden from a coal seam or series of coal seams. In contour mining, surface mining machinery follows the contours of a coal seam or seams around a ridge excavating the overburden and recovering the coal seam or seams as a "contour bench" around the mountain is created.
Mountaintop removal mining (MTR) is a form of surface mining increasingly being used to replace underground mining to extract coal from the Appalachian Mountain regions of eastern Kentucky, southwest West a, southwest ia and eastern Tennessee. The process involves using explosives to remove up to 1,000 vertical feet of rock to reach the coal seams.

Mining Illinois Coal Knight Hawk Coal, LLC has been at the forefront of the Illinois Coal Basin's recovery since the mid-1990s. With both surface and underground operations and a dock on the Mississippi River, Knight Hawk has immediate access to ship high-quality, low-chlorine coal to markets throughout the United States and for global export.
The Division of Mine Reclamation and Enforcement (DMRE) is responsible for inspecting all surface and underground coal mining permits in the state to assure compliance with the 1977 Federal Surface Mining Control Act (SMCRA).
Highwall Miner ( 1 ) ( 2 ) The machine is generally operated from a bench that is created by the removal of overburden material and coal by way of contour surface mining around the perimeter of a coal seam.
The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7) .
