A total of 64 workers were underground when the fire broke out in a shaft at the Vershino-Darsunsky mine in the Chita Region, five time zones east of the capital, at 8:15 a.m. Moscow time (4:15 a.m. GMT) Thursday.
In all, 31 miners were evacuated in the immediate aftermath after the blaze, which happened at a depth of between 85 (280 feet) and 135 meters (425ft), and 22 workers are still missing.
The ongoing search and rescue operation involves 120 representatives from local emergency services and two rescue teams who have arrived from the Kemerovo Region in southwestern Siberia.
Mines in the former Soviet Union have endured a poor safety record in the last fifteen years. Three miners were killed in a blast in another Siberian shaft in August and six men lost their lives in an accident at a Ukrainian pit in the same month.
