The Coal Mines Act 1930 was an Act of Parliament which introduced a system of quotas in the coal mining industry of Great Britain. It was a major achievement of the Labour Party, which revoked the eight hour day that had been enacted in 1926, replacing it with a 7 1⁄2 hour day. Mine owners were allowed to fix quotas and minimum prices.
