Sept 25 (Reuters) - Sev.en Global Investments will acquire a 51% stake in mining company Coronado Global Resources from the Energy & Minerals Group (EMG), it said on Monday, as the Czech-based investment group expands in metallurgical coal.

Coronado Global Resources has three mining complexes in Australia and the U.S. and has annual coal production of 16 million tonnes.

"We believe that Coronado has established a successful business strategy and we will support the company in continuation of its business strategy to grow and strengthen its position both in the U.S. and Australia," Sev.en Global Investments Chief Executive Alan Svoboda said in a statement.

Metallurgical coal, or coking coal, is used in the production of steel.

Czech billionaire Pavel Tykac, who owns Sev.en Global Investments, told Reuters in May that he was looking for acquisitions in the U.S. and Australia to continue his string of deals involving power production, coal and mining rights that sought high yield in sectors shunned by others.

The financial terms of the deal were not disclosed. (Reporting by Jan Lopatka, writing by Alan Charlish, editing by Susan Fenton and Josie Kao)
