Miners die when power cut stops ventilators

Two miners died on Thursday night, when ventilators in the Doubrava mine in the Karvina district of north Moravia stopped working due to a power cut. Police said, however, that a siren had alerted miners to the cut and the two men, aged 34 and 35, should not have entered the shaft. An investigation into the accident has been launched. Twelve miners have died in mines in Ostrava and Karvina so far this year, according to operators OKD.
