It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.
As the National Mining Association reports, the coal industry is a vital source of jobs that create positive ripple effects throughout society and our economy. These include the direct employment of nearly 150,000 people and the creation of 3.3 jobs for every job in coal mining, for a total of more than 500,000 jobs.

Coal ash surface impoundments and landfills must operate and close in a manner that protects public health and the environment," said EPA Administrator Michael S. Regan. "For too long, communities already disproportionately impacted by high levels of pollution have been burdened by improper coal ash disposal. Today's actions will help us ...
Last week, the U.S. Treasury Department and Internal Revenue Service (IRS) released guidance that provides detailed information about the bonus under the Inflation Reduction Act (IRA) for clean energy projects and facilities located in communities historically part of energy production, e.g., coal communities. The energy community bonus for the …
2. Abundance and forms of sulfur in coal. The sulfur content in coals varies considerably but is most commonly within the range of 0.5% to 5% total sulfur. The coal with less than 1% sulfur is classified as low-sulfur coal. Coal with 1% to < 3% sulfur is medium-sulfur coal. Coal with ≥ 3% sulfur is high-sulfur coal.
Coal mining is dark, dirty, and dangerous work. It's not for everyone — it's for the few who love to descend into the bowels of the Earth to extract "black gold." Even as they face the risk of...
An OOPArt in Illinois Coal On June 11, 1891, an Illinois newspaper reported the unusual discovery of a modern artifact found embedded in a lump of coal that had originated from a South Illinois …

Coal is a sedimentary deposit composed predominantly of carbon that is readily combustible. Coal is black or brownish-black, and has a composition that (including inherent moisture) consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.
One major cause of clinkers is coal that is of poor quality, which usually means it's too soft. Soft coal has more water in it, and it may also have a high concentration of sulfur, iron and minerals associated …
Lignites and bituminous coals are mostly used for power generation. Lignite and sub-bituminous coals release slightly more carbon dioxide than bituminous coals when they burn. Those differences are...
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder …
Coal is slightly denser than water (1.0 megagram per cubic metre) and significantly less dense than most rock and mineral matter (e.g., shale has a density of about 2.7 megagrams per cubic metre and pyrite of 5.0 …
This paper is a review of several important aspects of geochemistry of sulfur in coals, including (1) the abundance and distribution of sulfur in coal seams, (2) abundance of sulfur in coal lithotypes and macerals, (3) characteristics and geochemical significance of sulfur-containing organic compounds, (4) sulfur isotopic studies relating to …
Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits.
The most common volatile matter in coal is water, carbon dioxide, and sulfur dioxide. Volatile matter is directly related to coal rank; as rank increases, volatile matter content decreases (Stach and others, …

per million Btu. Carbon dioxide (CO2) forms during coal combustion when one atom of carbon (C) unites with two atoms of oxygen (O) from the air. Because the atomic weight of carbon is 12 and that of oxygen is 16, the …
A resident of Vladivostok, which is sandwiched between China, North Korea, and the Sea of Japan, was adding ordinary coal to a fire when he noticed a shiny metal object peeking through a piece of the friable black rock.1 The portion that protruded looked suspiciously manmade, so he investigated by enlisting the help of nearby scientists. The …
