Russian Prime Minister Vladimir Putin said he will introduce systematic changes to improve safety in the country’s coal industry following the Raspadskaya blast that killed at least 67 miners last month in Siberia.

Putin said there is a need for systematic changes in the country’s coal industry, signalling mine closures and tighter supply in global markets.

Russia’s safety watchdog Rostekhnadzor will now directly report to the government and hold the right to close down coal mines for safety violations.

Putin said the industry’s wage payment system will be reviewed and a new civil liability insurance law implemented to force owners to invest in safety measures.

The prime minister said new technologies could also be used to improve safety in underground coal mines.

The country’s major coal exporters said output and exports have dropped due to recent mine safety inspections.
