Two mines of the state-owned company Lvivvuhillya have stopped work over wage arrears, a representative of the Independent Trade Union of Miners of Ukraine at the Mezhyrichanska mine has said, according to Ukrainian News.
The Mezhyrichanska mine suspended operation on 6 June and the next day it was joined by the Lisova mine.
"Wages for March-April were not paid in full," he said.
According to miners, wage arrears at Lvivvuhillya exceed 200m hryvnyas (7.54m dollars).
If the wages are not paid, miners threaten to blockade the international motorway Lviv-Rava Ruska on 10 June.
As reported earlier, two miners at the Lisova mine were killed during a cave-in on 29 May.
