U.S. Coal Reserves

Compared to petroleum deposits, coal deposits are easily found and measured, but reserves are difficult to measure due to differences between the amount of coal in the ground and the amount of coal that will ultimately be mined, assuming constraints ranging from physical barriers to technological limitations to environmental regulations. As Table 1 shows, even in the comparatively well-studied United States, the exact definition of reserves and resources results in a 200-fold difference between U.S. estimates of "total resources" (4,000 billion short tons) and "recoverable reserves at active mines" (19 billion short tons).


Table 1: U.S. Coal Resources and Reserves in 2005[1]

Category Amount (billion short tons)
Recoverable Reserves at Active Mines 19
Estimated Recoverable Reserves 270
Demonstrated Reserve Base 490
Identified Resources 1,700
Total Resources (above plus undiscovered resources) 4,000

Ownership of U.S. coal reserves

Mountaintop Removal

For more details, see Mountaintop removal.

Mountaintop removal mining (MTR) is a form of surface mining increasingly being used to replace underground mining to extract coal from the Appalachian Mountain regions of eastern Kentucky, southwest West Virgina, southwest Virginia and eastern Tennessee[27]. The process involves using explosives to remove up to 1,000 vertical feet of rock to reach the coal seams. The resulting debris is often scraped into the adjacent valleys in what is called a valley fill. [28][29][30]

Because of the physically destructive nature of the practice, MTR is controversial and has received national and international media attention prompted by a groundswell of grassroots activism and resistance by local residents, environmentalists, social justice activists and others[31][32].

Environmental Impacts

Coal mining, especially mountaintop removal, has a number of adverse effects on the environment:

  • the release of methane (CH4), a potent greenhouse gas estimated to account for 18% of the overall global warming effect triggered by human activities (CO2 is estimated to contribute 50%).[33]
  • drastic alteration of the landscape, which can render an area unfit for other purposes, even after coal mine reclamation.[34]
  • the release of carbon monoxide (CO) from explosives, which pollutes the air and poses a health risk for mine workers.[34]
  • dust and coal particles stirred up during the mining process, as well as the soot released during coal transport, which can cause severe and potentially deadly respiratory problems.[34]
  • water pollution, as sulfuric acid forms when coal is exposed to air and water, creating an acid run-off with heavy metals.[33] Seepage from coal sludge can also infect local water supplies.[34]

Proposed coal mines

  • Crow Reservation, Montana - In April 2008, operators of the Absaloka Mine in southeastern Montana proposed to extend the mine 3,660 acres onto the neighboring Crow tribe reservation.[36] The mine would serve a proposed $8 billion coal-to-liquids plant.[37]
  • Sage Creek Mine, Colorado - Peabody Energy and Twen­tymile Coal Company hope to begin construction on the new underground Sage Creek Mine in West Routt County, CO as early as 2010.[40]
