* Licensing issues have delayed coal projects
* Coking coal deposits viewed as strategic assets
WARSAW/LONDON, May 13 (Reuters) - Poland's prime minister and other government officials will meet on Tuesday to discuss a threat by Australia's Prairie Mining PDZ.AX to sue Warsaw over difficulties it faced in developing coal projects, three sources familiar with the situation said.

Polish daily Dziennik Gazeta Prawna reported that Prairie could seek as much as 10 billion zlotys ($2.6 billion) in compensation from the government over alleged obstruction of construction at the Jan Karski and Debiensko mines.

JSW, the European Union's biggest coking coal producer, plans to bid for a controlling stake in Prairie in an attempt to boost future output.
That plan, however, is opposed by the energy minister, who is reluctant to let foreign investors have any access to coal deposits considered strategic assets for Poland's energy security. of the sources said Prairie had retained Swiss dispute lawyers Lalive.
