Anthracite

Anthracite has the highest carbon content among all types of coal, typically 86-97% carbon. The four types of coal in order of increasing carbon content are: Peat (lowest), Lignite, Bituminous, and Anthracite (highest). Higher carbon content means better quality coal with higher calorific value and cleaner burning properties. Anthracite is the most mature form of coal, formed under the highest pressure and temperature conditions.

Digboi

Petroleum was first discovered in India at Digboi in Assam. Until India's independence, Digboi was the only region producing petroleum in the country. This discovery marked the beginning of India's petroleum industry. Later, other oil fields were discovered in Assam and other states, but Digboi holds the historical significance of being India's first oil discovery. The Digboi refinery is also one of the oldest operating refineries in the world.

Bombay High

Bombay High is India's biggest oil deposit. It is an offshore oil field located about 110 km away from Mumbai in the Arabian Sea. Oil was discovered here in 1974 and production started in 1976. Being an offshore field, it required advanced technology for extraction. Bombay High has been crucial for India's petroleum production and has significantly contributed to reducing India's dependence on oil imports.

Black Diamond

Coal is called 'Black Diamond' due to its immense economic importance and multiple uses. Just as diamonds are precious stones, coal is considered precious for its energy value and industrial applications. Coal is not only used as an energy source but also in manufacturing insect repellents, explosives, artificial fibers, plastics, and chemical fertilizers. This wide range of applications and its crucial role in industrial development earned it this valuable nickname.
