Strip Mining Encyclopedia

However, the most common association of strip mining is with coal. The examples of decimated land in Appalachia have motivated calls for prevention, or at least major efforts at reclamation. Strip mining for coal comprises well over half of the land that is strip-mined, which totaled less that 0.3% of land in the United States between 1930 and ...

Strip mining - Encyclopedia Britannica

Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of ...

Strip Mining - an overview ScienceDirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004. 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

mining: Surface Mining Methods Infoplease

Strip mining (see coal mining), open-pit (or open-cut) mining, and quarrying are the most common mining methods that start from the earth's surface and maintain exposure to the surface throughout the extraction period. The excavation usually has stepped, or benched, side slopes and can reach depths as low as 1,500 ft (460 m). In strip mining, the soft overburden, or waste soil, overlying the ...

Surface mining, strip mining, quarries SpringerLink

Once referred to as strip mining, these surface methods are now generally known as surface mining. Surface mines, open pit mines, and quarries differ in important ways. Surface mines are developed to mine a material (often coal) which lies in a narrow bed relatively close to the surface. The bed of material can be removed and the surface restored such that, if done properly, the site can ...

Mining Encyclopedia

Mining can occur either at Earth ’ s surface in strip mines or open pit mines, or beneath the surface in underground mines. The method used depends on the depth, lateral extent, and economic value of the rock being mined. The deepest underground mine on Earth, which is 2.4 mi (3.8 km) deep, is a South African gold mine. The open-pit Bingham Canyon Mine near

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.

22/12/2012  The three main types of surface coal mining are strip mining, open-pit mining, and mountaintop removal (MTR) mining. Surface Mining: Strip Mining Strip mining is used where coal seams are located very near the surface and can be removed in massive layers, or strips. Overburden is usually removed with explosives and towed away with some of the largest vehicles ever made. Dump

Negative Effects of Coal Mining - The World Counts

Destruction of Landscapes and Habitats: Strip mining also known as surface mining, involves the stripping away of earth and rocks to reach the coal underneath. If a mountain happens to be standing in the way of a coal seam within, it will be blasted or levelled - effectively leaving a scarred landscape and disturbing ecosystems and wildlife habitat.

Significant strip-mining activity in the eastern Oklahoma coal field began about 1915. Large-scale surface mining commenced in the 1920s with the development of mechanized earth-moving equipment. By 1940 half of Oklahoma's annual coal production was recovered by surface mining, and at the end of the twentieth century 95 percent of the state's coal production came from surface mines. At the ...
