China mine rescue: Miners saved after knocking on pipe

Two Chinese miners rescued after being trapped underground for two weeks have described how they made contact with rescuers – by knocking on a pipe.

They also spoke of their relief at being free, with one saying he “feels reborn”, in their first comments since their dramatic rescue.

They were among 11 people pulled out alive after a 10 January blast in their gold mine in China’s Shandong province.

Rescuers are still searching for one miner who remains unaccounted for.

Nine others have been found dead, while another died last week in the mine after falling into a coma.

Speaking from his hospital bed on Tuesday, a miner identified as Du An told state media outlets: “When we heard the drills for the shaft nearing us, all of us stood up… we were too excited.

“There are no words to describe this feeling. I feel like I am reborn.”

“We were trapped nearly 600m below ground, it was a daunting task,” said another man, identified as Wang Kang. “We are so happy.”

How did the men make contact with rescuers?
The miners also gave more details to the media about what happened to them after the blast.

The group of 22 men had been working on different parts of the mine, around 600m (2,000ft) beneath the surface, when the unexplained explosion happened, severely damaging entry to the mine and cutting off communication.

Recalling the first moments of the explosion, Mr Wang said that he could not see anything clearly when it happened. “It blasted us really far away, and our safety helmets cracked. After it was over, we quickly tried to look for other people.”

For days, Mr Wang and Mr Du’s group of 11 miners waited in vain to be rescued – they would only learn afterwards that company officials had reported the accident after a 30 hour delay. They had no food and sustained themselves only on water.

“There was plenty of water down there, but it’s not very suitable for drinking. So we would only drink a little bit of it to survive,” said Mr Du.

But he said they tried to keep up spirits throughout. “We comforted each other with encouraging words. That’s how we pulled through.”

Initial reports had said rescuers first realised there were survivors when they felt a pull on a rope lowered into the mine. But state media on Tuesday said the first sign of life was actually the sound of knocking on a pipe.

The miners told reporters that every day one member of the group would knock on a drill pipe that led to the surface.

Finally on 17 January, as Mr Wang knocked on the pipe five times – to indicate that they were in the fifth section of the mine – they were finally heard by rescuers, who knocked back in response.

“I heard over 20 knocks, but I didn’t understand,” said Mr Wang.

“I went back to discuss it with the other miners. We thought that could mean the number of miners underground, so I returned [to the pipe] and responded with 22 knocks.”

How did the miners survive?
Rescuers eventually drilled a long, thin communication shaft down which they sent food, medicine, paper and pencils.

A paper note was then sent up on a rope from the group of 11 miners and a 12th trapped further below. A telephone line was also later established.

After that, contact with the 12th miner was lost, while one of the group of 11, who had fallen into a coma after sustaining a head wound in the explosion, was confirmed dead.
