Strip Mining is a technique used for near-surface, relatively flat sedimentary mineral deposits. How deeply the mining can occur is fundamentally determined by the combination of technological abilities and the economics involved.The most usual association of strip mining is the production of coal. Strip mining for coal includes over half of the land that is strip-mined, which totaled less than 0.3% of land in the United States between the years 1930 and 1990.
