Bulgarian miners are resuming work at the country's biggest coal mines, ending a weeklong strike that led to a halt in electricity exports to neighboring countries.

Union leader Konstantin Trenchev said on Sunday that a compromise deal has been struck with management that includes cash bonuses for the miners and an improvement in working conditions.

The three open pit mines of the state-owned company supply coal to four thermal power plants, whose output covers a quarter of the country's electricity needs.

Bulgaria also helps supply Greece, Turkey, Serbia and Macedonia but had to suspend exports due to the strike. The Balkan country exports more than 10 billion kilowatt hours of electricity per year.

It was not immediately clear when power exports will be restarted.
