Located in the northeastern part of the country, the Margherita coal reserves are known for their high-quality coal, which is widely used in power generation, steel manufacturing, and various other industries. With its strategic location and abundant deposits, Margherita plays a crucial role in India’s coal sector.

This blog delves into the importance of Margherita coal and its reserves, extraction methods, industrial applications, and prospects.

Understanding the Margherita Coal Reserves

The Margherita coal reserves are in the Tinsukia district of Assam, a region rich in natural resources. The coal deposits are primarily sub-bituminous, known for their moderate energy output and relatively low ash content.

Key Features of Margherita Coal:

• Type: Sub-bituminous coal
• Carbon Content: Moderate to high
• Calorific Value: Suitable for power generation and industrial use
• Ash Content: Lower than many other Indian coal varieties
• Sulfur Content: Comparatively low, making it environmentally favorable

The Margherita coal belt extends across several mining areas, with some of the most significant mines operated by North Eastern Coalfields (NEC), a Coal India Limited (CIL) subsidiary.

Significance of Margherita Coal in India’s Energy Sector

Coal is a crucial component of India’s energy mix, and Margherita coal plays a significant role in fulfilling the country’s demand. It supports various industries by providing a steady fuel supply and contributes to the state’s economic growth.
