"Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as "overburden removal". It is most commonly used to mine coal and lignite (brown coal). Strip mining is only practical when the ore body to be excavated is relatively near the surface. This type of mining uses some of the largest machines on earth, including From Shovels to Machines - National Coal Heritage Area,Beginning in the late 1940s, coal companies rapidly introduced longwall and continuous mining machines.

Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.Savings in coal mining | PR | Wirtgen,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. The main advantages of Wirtgen surface mining technology include the following:Surface Miners Optimize Coal Mining | PR | Wirtgen,The only requirement for companies to fully leverage the benefits of the surface mining process is to use intelligent machine solutions. The 220 SM 3.8 is one such solution that has demonstrated its exceptional value at mines around the world, including the Bhubaneswari coal mine.COAL EXTRACTION AND PROCESSING,treacherous conditions. “Coal-cutting” machines were introduced in the 1880s. By 1912, surface mining was performed by using steam shovels designed for coal mining.

Production reached 18.4 million tons by 1947. As early as 1939, West Virginians were concerned about the environmental impact of surface mining, and the legislature passed a bill on March 11 of that year,coal mining | Definition, History, Types, & Facts | Britannica,Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.Coal | National Geographic Society,Dec 22, 2012· Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.Mining - Global Civil and Mining,This makes it possible to mine thin seams such as coal, or separate high- and low-grade pockets of ore that would otherwise be uneconomical or heavily diluted with drill and blast methods. Many Machines in One.

To assist in this effort, some companies utilize computer aided reclamation design to develop exactMining Coal - Coal Education,Continuous-mining machines are used to remove the coal. As the machine breaks the coal, large arms gather the coal on a conveyor belt. The conveyor belt then carries the coal away from the seam, and it is loaded into shuttle cars. The mining machine is then moved to the next area to be mined. This method of mining leaves almost half of the coal,
