[ Coal in mountaintops is extracted by digging strips in the landscape to reach the coal. Mountaintop removal has been practiced since the 1960s.[8] Increased demand for coal in the United States, sparked by the 1973 and 1979 petroleum crises, created incentives for a more economical form of coal mining than the traditional underground mining methods involving hundreds of workers, triggering the first widespread use of MTR. Its prevalence expanded further in the 1990s to retrieve relatively low-sulfur coal, a cleaner-burning form, which became desirable as a result of amendments to the U.S. Clean Air Act that tightened emissions limits on high-sulfur coal processing. ] User: Closing mines has no economic impact on communities.
