Which one of the following coalfields belong to lignite type coal deposit?

The correct answer is 'Makum, Assam' Key Points Lignite Coal: Lignite, often referred to as brown coal, is the lowest rank of coal due to its relatively low heat content and carbon content. It is primarily used in electricity generation. In India, lignite deposits are primarily found in states like Tamil Nadu, Gujarat, Rajasthan, and Assam. The Makum coalfield in Assam is known for its lignite coal deposits, which are less dense and have higher moisture content compared to other types of coal. Additional Information Raniganj, West Bengal: Raniganj is one of the oldest coalfields in India, known for its rich deposits of bituminous coal. Bituminous coal has a higher carbon content and calorific value compared to lignite, making it more efficient for use in industries and thermal power plants. Singrauli, Madhya Pradesh: Singrauli is known for its extensive reserves of non-coking coal, which is primarily used for power generation. Non-coking coal is different from lignite as it has a higher carbon content and is less moist, leading to higher energy efficiency. Talcher, Odisha: Talcher coalfields are notable for their reserves of bituminous and sub-bituminous coal, which are extensively used in thermal power plants. Sub-bituminous coal has a higher calorific value and carbon content compared to lignite, making it more preferable for industrial use. Important Points Lignite coal is primarily used in electricity generation due to its lower heat value and higher moisture content. India has significant lignite coal deposits, which are essential for meeting the country’s energy demands, especially in regions where other types of coal are scarce. Understanding the type of coal available in different regions helps in planning and optimizing the utilization of coal resources for various industrial and energy production needs.
