During a meeting on the situation in the coal industry of Kuzbass, Putin said that he had received a document from the Investigative Committee on the accident.

“The reason for the accident was the lack of control by the management of the mine over the production of work ... carried out with an increased gas content of methane,” RIA Novosti quotes him.

The document also says that the authorized employees of Rostekhnadzor, in violation of the requirements of the legislation on the permanent control of facilities of the first hazard class, did not carry out inspections at the mine and did not take measures to suspend work.

Putin also called for tougher responsibility for violations of safety requirements in the coal industry.

Earlier, the president demanded to establish all the causes and circumstances of the accident at the Listvyazhnaya mine in the Kemerovo region.

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