RAS question
The Jharia coalfield, the richest coalfield in India, is in which state?
Correct answer: (D) Jharkhand.
The Jharia coalfield, India's richest coalfield, is located in Jharkhand, in Dhanbad district.
Explanation
Jharia is a Jharkhand coalfield, not a Bihar, Odisha or West Bengal one. The official BCCL report locates the Jharia Coalfield in the north-east part of Jharkhand and notes that the coalfield lies in Dhanbad district. That location matters because the MCQ is testing the standard coalfield-state pairing: Jharia equals Jharkhand. Its importance is not just geographical. Jharia is India's only source of prime coking coal, which is essential for steel production, and the area has also been affected by long-running underground coal fires for over a century. So the answer is Jharkhand, with Dhanbad as the precise district anchor.
Why the other options are wrong
- (A) Bihar is a tempting legacy answer because Jharkhand was carved out of Bihar in 2000, but Jharia is now in Dhanbad district of Jharkhand.
- (B) Odisha has coal-bearing areas, but BCCL places Jharia in Jharkhand, not Odisha.
- (C) West Bengal is associated with the Raniganj coalfield, while Jharia is the Dhanbad district coalfield of Jharkhand.
Concept
This tests Indian mineral and energy-resource geography: matching a major coalfield with its present state and district. It recurs in RAS because coalfields link location, industrial raw material, and regional economic geography in one factual prompt.
