Coal mining in the United States

Coal, primarily from underground mines east of the Mississippi, was the nation's primary fuel source until the early 1950s. Surface (strip) and mountaintop removal mining overtook underground mines in the 1970s. In 2000, the majority of coal was produced west of the Mississippi. == Production ==

In 2018, coal mining decreased to 755 million short tons, and American coal consumption reached its lowest point in nearly 40 years. In 2017, U.S. coal mining had increased to 775 million short tons. with an average price of $31.83 per short ton, worth $28.6 billion. declined 16 percent, the Appalachian Basin declined 32 percent 2008 to 2014, and the Illinois Basin increased its production 39 percent from 2008 to 2014. In 2015, five states—Wyoming, West Virginia, Kentucky, Illinois, and Pennsylvania—produced almost 3/4 of all coal production nationwide. Wyoming produced 375.8 million short tons representing 42% of U. S. coal production, West Virginia produced 95.6 million short tons or 11%, Kentucky was third with 61.4 or 7%, Illinois was fourth with 56.1 or 6%, and Pennsylvania was fifth with 50.0 or 6%. Coal production by type The hardest coal, anthracite, originally used for steel production, heating, and as fuel for ships and railroads, had by 2000 dwindled to an insignificant portion of production. Softer bituminous coal replaced anthracite for steel production. The even softer sub-bituminous and lignite coals overtook bituminous for power generation in the 2000s. == Companies ==

In 2018, the production owned by the top ten companies was 71.6% of total US coal production. In 2018, the production owned by the top 23 companies was 87.9% of the total US coal production. == Coal mining employment ==

At the end of July 2022, the coal industry employed approximately 41,100 miners. US employment in coal mining peaked in 1923, when there were 863,000 coal miners. Since then, mechanization has greatly improved productivity in coal mining, so that employment has declined at the same time coal production increased. The average number of coal mining employees declined to 41,600 in 2020. Because of the sharp declines in the U.S. coal industry, the Harvard Business Review discussed retraining coal workers for solar photovoltaic employment because of the rapid rise in U.S. solar jobs. A recent study indicated that this was technically possible and would account for only 5% of the industrial revenue from a single year to provide coal workers with job security in the energy industry as whole. == Exports ==

The U.S. is a net exporter of coal. US net coal exports increased ninefold from 2006 to 2012, peaked at 117 million short tons in 2012, and were 97 million short tons in 2017. The largest individual country export markets were the Netherlands (12.9 million short tons), India (6.4 million short tons), Brazil (6.3 million short tons), and South Korea (6.1 million short tons). Coal exports to China, formerly one of the major markets, declined from 8.3 million short tons in 2013, down to 0.2 million tons in 2015. In 2012, six coal export terminals were in the planning stages in the Pacific Northwest. They were scheduled to be supplied by strip mines in the Powder River Basin. The export markets were South Korea, Japan, China, and other Asian nations. Like the Keystone Pipeline the building of the terminals raised environmental concerns with respect to global warming. As of February 2016, four proposals for coal terminals had been withdrawn, leaving two still applied for. The withdrawals were ascribed to loss of demand and consequent lower coal prices. == Usage ==

In 2013, 92.8 percent of US internal coal consumption was for electricity generation. Other uses were industrial (4.7 percent), coke manufacture (2.3 percent), and commercial and institutional (0.2 percent). In 2016, the EIA calculated that coal would provide 30% of electricity generation nationwide, with natural gas providing 34%, nuclear 19%, and renewables 15%. Both the tonnage of coal used for electricity (1047 million short tons) and the amount of US electricity generated from coal (2020 TWh) peaked in 2007. By 2015, electrical generation from coal had declined to 1360 TWh and 966 TWh in 2019, as coal's share of total electrical generation in the US fell from 48.5 percent in 2007, to 33.1 percent in 2015, to 23 percent in 2019, and 19% in 2020. Most of the decrease in coal electricity was offset by an increase in generation from natural gas-fired power plants. In 2006, there were 1493 coal-powered generating units at electrical utilities across the US, with total nominal capacity of 335.8 GW (compared to 1024 units at nominal capacity of 278 GW in 2000). Actual power generated from coal in 2006 was 227.1 GW (), the highest in the world and still slightly ahead of China () at that time. In 2000, US production of electricity from coal was 224.3 GW (). As of 2013, domestic coal consumption for power production was being displaced by natural gas, but production from strip mines utilizing thick deposits in the western United States such as the Powder River Basin in northern Wyoming and Southern Montana for export to Asia increased. In 2014, 3.0 percent of the coal shipments from Montana and Wyoming were exported. The 2014 coal exports from the two states of 13.4 million short tons represented an increase of 1.2 million tons over 2012 export levels, which is 0.3 percent of the states' 2014 total coal shipments of . == Coal mining on federal lands ==

As of 2013, 41 percent of US coal production was mined from federal land, almost all of it in the western US, where federal coal makes up about 80 percent of mined production. The federal coal program is overseen by the Bureau of Land Management (BLM) under the US Department of Interior. Federal coal lands are leased by competitive sealed bids, for the highest bonus (initial payment) offered. In addition, the government receives an annual rental of $3 per acre, and a fixed percentage royalty of the market value of coal produced. The royalty is 8 percent for underground mines and 12.5 percent for surface mines. In 2014, the program generated about $1.2 billion in lease bonuses, rentals, and royalties for coal mining on federal lands. This would affect 50 licenses. The Trump administration reversed the moratorium. The Government Accountability Office has questioned whether bonus and royalty rates reflect coal's market value. Per GAO, since 1990 Colorado earned about $22 million less from bonus bids than Utah, though Colorado leased out almost 76 million tons more coal than Utah. BLM personnel noted that the coal mined in Utah was closer to its market, and so was more valuable due to lower transportation cost. The institute's mission statement notes that its goals include: "… to reduce dependence on coal and other non-renewable energy resources." == Energy value ==

The average heat content of mined US coal has declined over the years as higher-rank coal production (anthracite, and then bituminous coal) declined, and production of lower rank coal (Sub-bituminous and lignite) increased. The average heat content of US-mined coal decreased 21% from 1950 to 2016, and 6.8% in the 20 years from 1996 to 2016. The tonnage of mined coal hit a peak in 2008, and has declined since. The energy value of mined US coal hit its all-time peak a decade earlier, in 1998, at 26.2 quadrillion BTU. The energy value of US coal mined in 2016 was 14.6 quadrillion BTU, 44 percent lower than the peak. == Accidents ==

Mine disasters have still occurred in recent years in the US, Examples include the Sago Mine disaster of 2006, and the 2007 mine accident in Utah's Crandall Canyon Mine, where nine miners were killed and six entombed. In the decade 2005–2014, US coal mining fatalities averaged 28 per year. 2016 was the first year in U.S. coal mining history that had no fatalities due to coal mine roof falls. == Human and environmental health ==

Accidents are not the only threat to modern coal miners and those living in coal regions. Respiratory disorders from coal dust and heart disease are both prevalent, especially in the West Virginia Appalachian coal mining region. When mountaintop removal mining is used, not only do the miners suffer, but people living in the regions develop health issues. Excess rock, also known as overburden, removed from the mountains is dumped into valleys creating toxic runoff, that often pollutes streams used for local water sources or even the groundwater and wells. Burning coal releases CO2 into the atmosphere which is contributing to global climate change. In addition to the respiratory and cardiac illnesses that remain a threat to coal miners, these individuals are also at risk for mental health related issues. While short term, coal extraction companies can create more jobs within communities and increase capital investment, research has shown that these heavily coal dependent communities have suffered when it comes to their mental and emotional health. According to the Gallup-Healthways Index, in the years 2009 and 2010, West Virginia, one of the top contributors of coal in the United States, ranked last in "Physical Health," "Emotional Health," "Life Evaluation," as well as "Overall Well-Being." On top of that, it was also found that individuals who were closely involved or located near mountaintop removal sites were more at risk for higher mortality rates, developing life-threatening diseases, and total poverty than those who extracted coal underground. == Adverse economic impacts ==

Critics of coal mining in West Virginia sometimes refer to the mine locations as energy sacrifice zones, being loosely defined as areas where the health of the people and the environment has been sacrificed for the energy, jobs and profits that can be derived from the activity. Because of the poor economy in the region, coal mining is many miners' only economic option. While data can be misleading about the creation of jobs in mining regions, The authors, Perdue and Pavela, of "Addictive Economies and Coal Dependency," highlight the fact that communities with no mining had lower levels of poverty than the communities with mining. Perdue and Pavela blamed this on the fact that "dependency on natural resources resulted in stifled development and negative socioeconomic outcomes." According to the article, West Virginia is one of the top producers of coal. Regardless, West Virginia only contributed 7% to the gross product. == Opposition ==

Concern about global warming in the US – especially in the aftermath of Hurricane Katrina and Al Gore's receipt of the 2007 Nobel Peace Prize for his raising awareness of climate change – temporarily increased public opposition to new coal-fired power plants. Simultaneously with these events, the anti-coal movement in the US – similar to that in the UK and Australia – had made coal-fired power projects more politically costly, and spurred further shifts in public opinion against coal-fired power. In a 2004 effort to foster positive public opinion of coal, many large coal mining companies, electric utilities, and railroads in the U.S. launched a high-profile marketing campaign to convince the American public that coal-fired power can be environmentally sustainable, despite the fact that coal is the largest contributor of CO2 emissions in the electricity sector. However, some environmentalists condemned this campaign as a "greenwashing" attempt to use environmentalist rhetoric to disguise what they call "the inherently environmentally unsustainable nature of coal-fired power generation". == Reserves ==

The United States has 468.4 billion tons in the demonstrated reserve base as of 1 January, 2025. The energy content of this coal exceeds that of the country's oil and gas reserves. Due to several factors such as land rights or environmental restrictions, 249.4 billion tons are thought to be recoverable. == See also ==
