In the US, coal mining is a shrinking industry. In 1923, there were about 883,000 coal miners; today there are about 53,000. Working in coal mines is dangerous — miners have to deal with toxic gases, plus the threat of being crushed, drowned, or injured from fires and explosions.
Where do you find coal?
The largest coal reserves are in the United States, Russia, China, Australia, and India. In the United States, coal is mined in 25 states and three major regions. In the Western Coal Region, Wyoming is the top producer—about 40% of the coal mined in the country is extracted in the state.
How many years of coal is left in the US?
Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.

What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
How deep is coal usually found?
Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by the open pit methods, due to thickness of the seam 20–25 metres (60–90 feet).
How is coal detected?
Coal reserves are discovered through exploration activities. The process usually involves creating a geological map of the area, then carrying out geochemical and geophysical surveys, followed by exploration drilling.
