Polish state-operated miner Polska Grupa Górnicza (PGG) has announced that it has closed two of its mines until Sunday 3 May to limit the spread of Covid-19, following the confirmation of cases at the miner’s facilities.

PGG, which employs around 40,000 people, confirmed 70 cases of Covid-19 among its workforce at the Murcki Staszic and Ruch Jankowice operations, as the enclosed, often cramped working conditions of underground mines are conducive to the spread of the disease.

“Employee health and safety is a priority for us,” said Tomasz Rogala, PGG president. “We want to reduce the risk of illness among employees and ensure that after a period of epidemics, plants can function normally and safely.”
