COAL MINING Meaning and
Definition
-
Coal mining is the process of extracting coal from the earth's crust in order to utilize it as a fuel source. It is a crucial industry that has played a significant role in the development of modern society. Coal is a fossil fuel that is formed through the accumulation of plant remains over millions of years, subjected to high pressure and temperature. It is classified as a non-renewable energy source due to its finite nature and the extensive time it takes to form.
The process of coal mining involves several stages. Exploration is the initial step, where potential coal deposits are identified through geological surveys and drilling. Upon discovery, the site is prepared for mining, including the construction of underground shafts or open pits. Extraction techniques employed can vary depending on geographical and environmental factors. Common methods include underground mining, where coal is extracted by tunneling into the earth's crust, and surface mining, which involves the removal of layers of soil and rock to access the coal seam.
Once extracted, the coal goes through processing procedures to remove impurities and increase its purity and energy content. This includes crushing, washing, and sorting the coal into sizes suitable for different applications. The processed coal is then transported to power plants, industrial facilities, or domestic consumers for further use as a primary energy source in manufacturing, electricity generation, and heating.
Coal mining has been a vital industry, supporting economic growth and industrialization. However, it also poses various environmental challenges. The extraction process may result in land degradation, water pollution, and emission of greenhouse gases. These factors have pushed for the development and adoption of cleaner and more sustainable energy sources as alternatives to coal.

Etymology of COAL MINING
The word "coal mining" is composed of two words: "coal" and "mining".
The term "coal" originated from the Old English word "col", which can be traced back to the Proto-Germanic word "kula" and the Proto-Indo-European word "gel" or "gol". It is believed to have been borrowed from the Old Norse word "kola".
The word "mining" comes from the Old French word "mine" or "miner", which means "to dig a mine". It has its roots in the Latin word "minare", meaning "to undermine" or "to dig". The word further traces back to the Proto-Indo-European word "men", which refers to "to dig" or "to mine".
Combining these roots, "coal mining" refers to the process of excavating or extracting coal from the earth.
