1. Introduction
Coal remains a dominant energy source in India, powering the majority of the nation’s electricity generation. India has abundant coal reserves, which are primarily located in a few states, with several coal fields spread across different regions. These fields are crucial for the nation’s industries, such as power generation, steel, and cement manufacturing.
2. Types of Coal Found in India
India’s coal reserves are divided into four main types based on their carbon content and calorific value:
-
Anthracite Coal: The highest grade of coal, with the highest carbon content. It is found in limited quantities in India.
-
Bituminous Coal: The most common type of coal in India. It has a medium to high calorific value and is used mainly for power generation and industrial purposes.
-
Sub-bituminous Coal: Has a lower carbon content than bituminous coal, used mainly for thermal power generation.
-
Lignite: Also known as brown coal, it has a low calorific value and is used primarily for electricity generation.
3. Major Coal Fields in India
India’s coal fields are concentrated mainly in a few states: Jharkhand, Odisha, Chhattisgarh, Madhya Pradesh, West Bengal, and Telangana. Below are some of the most important coal fields:
