The Trade Unions International of Miners was a trade union international affiliated with the World Federation of Trade Unions.
The union was founded at a Constituent Conference in Florence, Italy held July 16–19, 1949.
In 1983 it expanded its scope, with unions including the British National Union of Mineworkers joining, and became the Trade Unions International of Miners and Energy Workers. In 1986 it became the Trade Unions International of Energy Workers before ceasing activities.
The TUI temporarily suspended activities after the collapse of communism in Europe, but re-emerged at a conference in Havana in 1998. I joined with the Trade Union International of Metal and Engineering Workers and the Trade Unions International of Chemical, Oil and Allied Workers to form the new Trade Unions International of Energy, Mining, Chemical, Oil and Allied Industries. This organization was reformed again in 2007 adopting the name Trade Union International of Energy Workers. The metal workers then formed a new Trade Union International of Workers in the Mining, the Metallurgy and the Metal Industries
The union had a controlling congress, a directing committee, a bureau and permanent secretariat. Special Commissions were also set up to deal with specific issues. In 1978 there commissions on the coal mining, other mining industries and health and safety. In 1985 there were commissions on energy, transnational corporations, peace and disarmament, as well as health and safety.
