India's coal production has significantly increased from 6.12 million tonnes in 1900 to 565.64 million tonnes in 2013-14, with steady growth seen post-nationalization in the 1970s. Major coal-producing states include Chhattisgarh, Jharkhand, Odisha, and Madhya Pradesh, while Coal India Limited dominates production, contributing approximately 82% of the total. The sector's growth may face challenges with production targets for 2016-17 unlikely to be met.
