strip mining definitions

WordNet (r) 3.0 (2005)

n
1: the mining of ore or coal from an open mine [syn: strip mining, opencast mining]

Britannica Concise

Removal of the soil and rock (overburden) above a seam of coal or other mineral and extraction of the exposed mineral. The method is used to best advantage where the mineral is not deeply buried, though many modern strip mines employ equipment capable of removing overburden nearly 200 ft (60 m) thick. In Europe the technique is widely used for brown-coal deposits, while in the U.S. a large proportion of both anthracite and bituminous coal is so mined. Strip mining is most economical where flat terrain and horizontal seams permit a large area to be stripped. Where deposits occur in rolling or mountainous terrain, a contour method is used that creates a shelf with a slope on one side and an almost vertical wall on the other. Strip mining has been criticized, especially in the U.S., for its damage to the local environment. See also placer mining.

Collin's Cobuild Dictionary

also strip-mining Strip mining is a method of mining that is used when a mineral is near the surface and underground passages are not needed. (AM; in BRIT, use opencast mining)
