Nationalisation of coal mines (1971-1975)

Coking coal mines were nationalised in 1972 and all remaining coal mines on 1 May 1973; Coal India Limited was formed in 1975. Private commercial coal mining was permitted again from 2018.

Facts

  • The Coking Coal Mines (Emergency Provisions) Act, 1971 allowed a temporary takeover; the Coking Coal Mines (Nationalisation) Act, 1972 nationalised coking coal mines on 1 May 1972 (except those of Tata Iron and Steel and Indian Iron and Steel), placing them under Bharat Coking Coal Limited [1].
  • All remaining coal mines were nationalised on 1 May 1973 under the Coal Mines (Nationalization) Act, 1973 [1]. Another account dates the takeover of the 711 remaining non-coking mines to 30 January 1973 [2].
  • Coal India Limited (CIL) was formed on 1 November 1975 as a holding company with five subsidiaries [2].
  • Coal output was about 30 million tonnes in 1946 and about 33 million tonnes at the start of the First Five Year Plan [1].
  • CIL's production was 79 million tonnes in 1975 and 781 million tonnes in FY 2024-25, according to a CIL official statement reported by IANS; the same statement describes CIL as accounting for about 75% of national output [3].
  • On 24 September 2014 the Supreme Court cancelled 214 of 218 coal blocks allocated to private and public companies between 1993 and 2010, having held on 25 August 2014 that the allocations were illegal [4].
  • A Cabinet Committee on Economic Affairs decision of 20 February 2018 allowed private firms into commercial coal mining; Wikipedia reports that the 1972 and 1973 nationalisation Acts were repealed on 8 January 2018 by the Repealing and Amending (Second) Act, 2017 [5].
  • Captive and commercial mines (those not operated by Coal India or its subsidiaries) produced 100.08 million tonnes between 1 April and 8 November 2024, up 33% year on year, according to a Ministry of Coal statement reported by PTI [6].

Why

Reasons given by those who did it

  • The Ministry of Coal's history states that the steel industry needed systematic exploitation of Jharia coking coal reserves, and that private owners had not provided enough capital to meet the country's energy needs [1].
  • The Ministry states that unscientific mining practices by some private owners and poor labour conditions in some mines were matters of concern for the Government [1].

Criticism of that reasoning

No criticism of the stated reasons is recorded yet.

Benefits and concerns

Benefits (2)

  • Large and sustained growth in output under the public-sector company.CIL produced 79 million tonnes in 1975 and 781 million tonnes in FY 2024-25 (CIL statement via IANS) [3]. National output was projected at 997.14 million tonnes for FY 2023-24 (PTI, citing government data), of which CIL about 760 million tonnes [7]. Demand growth over fifty years also contributed.
  • Domestic mines supplied most of the coal consumed.In 2020-21 domestic production covered 79.03% of the 906.08 million tonnes consumed [5].

Concerns (2)

  • The allocation of coal blocks under the exemptions to the state monopoly was ruled illegal by the Supreme Court.The Court held on 25 August 2014 that the screening-committee allocation of 218 blocks between 1993 and 2010 was 'ad hoc and casual' and non-transparent, cancelled 214 on 24 September 2014, and imposed Rs 295 per tonne on coal already mined [4].
  • Environmental compliance and safety have been questioned, and imports continue alongside domestic production.A 2011 CAG finding, reported by the Economic Times and cited by Wikipedia, was that CIL operated 239 mines without environmental clearance [2]. India imported 215.25 million tonnes of coal in 2020-21 [5]; imports are described as about 15% of supply in FY 2024-25 [5]. These figures do not by themselves show the cause.

Positive meanNegative meanScorer AScorer B

Scorer A. Coal India output rose from 79 to 781 million tonnes and domestic supply meets most demand, though demand growth, imports and later block-allocation illegality qualify this.

Scorer B. Coal India output rose from 79 to 781 million tonnes, though later block allocations were ruled illegal and the nationalisation Acts were repealed in 2018.

Context used when scoring

Era baseline
Coal output had grown slowly from about 30 million tonnes in 1946 to about 33 million tonnes at the start of the First Plan, with mining in private hands and the steel and power sectors expanding.

In depth

Coal nationalisation took place in two steps. Coking coal mines, needed for steel, were taken over in 1971-72, and all remaining mines followed on 1 May 1973. Coal India Limited was formed in 1975 to run the mines as a holding company with regional subsidiaries. The Ministry of Coal gives the reasons as steel-sector needs, inadequate private investment, and concerns about mining practice and labour conditions.

Since then output has risen from tens of millions of tonnes to several hundred million tonnes at CIL alone, though demand also rose substantially over the period and the data do not isolate the effect of ownership. The public monopoly was progressively opened: allocations of captive blocks from 1993 were ruled illegal by the Supreme Court in 2014, and a 2018 Cabinet Committee decision allowed commercial mining by private firms. Captive and commercial mines now produce a growing share.

Sources differ on some dates, including the 1973 takeover (1 May versus 30 January), and on whether the 1973 Act was repealed in 2018; the repeal claim here rests on a secondary source and has not been checked against the gazette. Safety and environmental figures cited are from secondary sources and are indicative only.
