At least 14 people were killed in a Russian coal mine in Siberia on Thursday, including three rescuers who were sent down to try to bring out dozens still missing.
At least 11 miners died in the initial accident, when coal dust ignited in a ventilation shaft in the Listvyazhnaya mine in the snowbound Kemerovo region, filling the mine with smoke, the Tass news agency cited local emergency services as saying.
It quoted the acting head of the emergencies ministry as saying three rescuers had also been killed. With methane levels in the mine dangerously high, an operation to rescue 35 people stuck underground had to be halted, regional governor Sergei Tsivilev said.
“The chance of an explosion is very high. We’ve decided to suspend the search and rescue operation until the concentration of gas reduces,” Mr Tsivilev said.
Dozens were being treated in hospital, at least some of them with smoke poisoning. Four were in critical condition.
The coal-producing region of Kemerovo, roughly 3,500km east of Moscow, has been hit by fatal mining accidents for years.
The mine is part of SDS-Holding, owned by the privately held Siberian Business Union. The owner had no immediate comment.
Before the rescue operation was halted, the governor said there was still electricity and ventilation in the mine, but that they had lost contact with some people deep underground.
“For now there is no heavy smoke, so we hope that there is no fire,” Mr Tsivilev said on his Telegram channel. “We have no communication lines with these people, the underground communications system is not working.”
Some 285 people were inside the mine when smoke spread through the ventilation shaft, the emergencies ministry said. At least 239 made it above ground, authorities said. They did not say what had caused the smoke.
On state television, President Vladimir Putin said he had spoken with the governor and emergency officials, describing the accident as a “great misfortune”.
“Unfortunately the situation is not getting easier. And there’s a danger to the lives of the rescuers ... We’ll hope they can save as many people as they can,” he said.
The Kremlin said Mr Putin had ordered the emergencies minister to fly to the region to help.
Kemerovo declared a three-day period of mourning.
In 2007, Kemerovo was the site of the worst mining accident since the 1991 collapse of the Soviet Union when an explosion at the Ulyanovskaya mine claimed the lives of more than 100 people.
In 2010, explosions at the region’s Raspadskaya mine killed more than 90 people.
The investigative committee law enforcement agency’s regional branch said it had opened a criminal case into negligence causing loss of life. – Reuters
