The head of Rostechnadzor called the cause of the explosions in the mine “some kind of anomaly”
The head of Rostekhnadzor, Alexei Aleshin, said that the cause of the accident at the Severnaya mine in Vorkuta could be "some kind of anomaly in the mined-out rocks." “Most likely, a large layer hung over, it did not collapse, although it should have collapsed, but sank down and squeezed out the remaining gas,” Aleshin said at a meeting with Russian President Vladimir Putin.
