Earlier, Russian President Vladimir Putin, during a meeting on the coal industry, criticized the board of directors of SDS-Ugol for non-compliance with safety conditions at the Listvyazhnaya mine in the Kemerovo region.

The head of state said that, according to the investigation, the reason for the tragedy at the Listvyazhnaya mine in the Kemerovo Region was the lack of control by the management of the mine over the work carried out with increased gas pollution.

On November 25, an accident occurred at the Listvyazhnaya mine in Kuzbass, as a result of which 51 people died and dozens were injured.
