History
Coal mining in India had primarily been a private sector enterprise. This changed in September 1956 when the Government of India established its own coal company National Coal Development Corporation (NCDC). Collieries run by the Railways formed the nucleus of NCDC. This was to fulfill the fast growing energy requirements in the country to support rapid industrialization taking place through Five-Year Plans of the Government. In the same year, Singareni Colliery Company, which was operating in Andhra Pradesh since 1920, was also brought under the Government control when the Central Government and state Government of Andhra Pradesh acquired 45% and 55% shares respectively. In 1971, the Government of India nationalized all the 214 coking-coal mines and 12 coke-ovens running in the private sector, excluding those held by TISCO and IISCO for their captive use. On 1 January 1972, a new Government company Bharat Coking Coal Limited (BCCL) was formed to take control of these nationalized mines and coke-ovens. On 30 January 1973, all the remaining 711 non-coking coalmines of the country in private sector were also nationalized. 184 of these mines were handed over to BCCL, and remaining 527 were handed over to a newly opened department Coal Mines Authority. 4 months later, on 14 June 1973, this department was converted into a separate Government company CMAL. NCDC, earlier formed in 1957, was merged with CMAL, and 45% share-holding of Central Government in Singareni Collieries Company Ltd was also handed over to CMAL. CMAL started functioning with its 4 divisions, viz, Eastern Coalfields, Central Coalfields, Western Coalfields, and Central Mine Planning and Design Institute. By 1973, all coking coalmines were under BCCL, which was functioning as a subsidiary of Steel Authority of India (SAIL) under Department of Steel of the Ministry of Steel and Mines; and all non-coking coalmines were under CMAL, which was under Department of Mines of the Ministry of Steel and Mines. For better control, both BCCL and CMAL were brought on 11 October 1974 under the Department of Coal (now an independent Ministry) of the newly formed Ministry of Energy. On 1 November 1975, a new public-sector company Coal India Limited (CIL) was formed to enable better organizational and operational efficiency in coal sector. All the 4 Divisions of CMAL were given the company status, and were brought under CIL along with BCCL. 45% share-holding of the CMAL in Singareni Collieries Company was also transferred to CIL, and CMAL was closed. Thus, CIL started functioning in 1975 with 5 subsidiary companies under it. These were Bharat Coking Coal Limited (BCCL), Eastern Coalfields Limited (ECL), Central Coalfields Limited (CCL), Western Coalfields Limited (WCL), and Central Mine Planning & Design Institute Limited (CMPDIL). In due course of time, 3 more companies were formed under CIL by carving out certain areas of CCL and WCL. These were Northern Coalfields Limited (NCL), South-Eastern Coalfields Limited (SECL), and Mahanadi Coalfields Limited (MCL). Pursuant to the Fuel Policy of 1974, CIL also started the construction of India's First Low Temperature Carbonisation Plant at Dankuni in the late 1970s. It was renamed as Dankuni Coal Complex, and is one of the only operational Coal gas plant of this kind in the world. Dankuni Coal Complex has been incurring heavy loss due to the Greater Calcutta Gas Supply Company (formerly known as Oriental Gas Co.) giving non-remunerative price and fixing them unilaterally. Coal India is planning to venture into Coal-to-Methanol technology at the existing Plant. The Government of India held 100% equity of CIL from 1975 till 2010. Initial public offering

In September 2011, CAG criticised CIL for operating 239 mines in seven coal producing subsidiaries, which existed prior to 1994, without environmental clearance. These mines included 48 open-cast, 170 underground and 21 combined mines. In its report, the CAG also pointed out that of the 18 sample open-cast and eight underground mines, ten mines had undertaken capacity expansion without environmental clearances. The company, in its reply, said that applications for clearances to the projects have already been submitted to the Ministry of Environment and Forests. In India, some coal mines are located near/below the tiger reserves. Mining or construction of administrative offices in/near these reserves disturbs the wildlife. Hence environmental organisations like Greenpeace have been opposing mining in these areas. Around 50% of the energy requirements of India are met by coal. Hence the protection of wildlife is sometimes overlooked due to this fact. In its argument, the CIL said that in many cases it only does underground mining which does not hurt the forests above. CIL reported lowest ever figures of average 66 deaths and 251 serious accidents per year for the period 2010-2012, indicating that safety at workplace is improving over the years. Critics claim that the safety practices in most mines are inadequate, which is causing too many casualties. It is also claimed that many accidents and deaths are not recorded and hence are not part of 'official figures'.
