BLACK COAL Meaning and
Definition
-
Black coal, also known as hard coal or bituminous coal, is a fossil fuel that is primarily composed of carbon along with various other chemical elements such as hydrogen, sulfur, oxygen, and nitrogen. It is formed from the remains of ancient plants that were exposed to high levels of pressure and heat over millions of years.
Black coal is typically characterized by its relatively high carbon content, low moisture content, and its ability to burn with a clean flame and high energy output. It is considered a non-renewable energy source and is widely used for electricity generation, as well as a fuel in industrial processes.
Due to its highly concentrated carbon content, black coal has a high calorific value, which refers to the amount of heat energy released when it is burned. This makes it an efficient source of energy, particularly for power generation.
Black coal is typically mined from underground or open-pit mines, depending on its location and accessibility. It is then processed to remove impurities and graded according to its quality, with higher-quality coal having lower sulfur and ash content.
While black coal is an abundant and widely used energy source, it also has significant environmental implications. Its combustion releases carbon dioxide (CO2), a greenhouse gas that contributes to climate change. As a result, efforts are being made to develop cleaner and more sustainable alternatives to black coal in order to reduce its environmental impact.

Etymology of BLACK COAL
The etymology of the word "black coal" can be traced back to the Germanic language family. The Old English word "col" derived from the Old High German word "kohlu" meaning "glowing coal" or "charcoal". Over time, the "k" sound in "kohlu" shifted to a "c" sound in Old English, resulting in the word "col". This term continued to evolve in Middle English as "cole" before eventually becoming "coal" in Modern English.
The addition of "black" to the word "coal" is primarily due to the visual appearance of the material, which is often dark in color. This helps distinguish it from other forms of coal, such as lignite or anthracite, which may have different shades or characteristics. Therefore, the term "black coal" is often used to specifically refer to the dark, commonly found variety of coal.
