One miner has already died and another 10 remain missing.
Rescue workers on Sunday successfully lifted out one of 22 miners trapped for two weeks hundreds of metres underground in an east China mine, reported state broadcaster CCTV. He was brought to the hospital for treatment, with his condition described as "extremely weak".
On Sunday morning the huge obstacles suddenly fell to the bottom of the shaft, allowing the operation to take a big step forward, rescue expert Du Bingjian said.
The workers' escape is similar to the rescue of 33 miners trapped in the San Jose copper-gold mine in Chile for more than 69 days in 2010.
Chen Yumin, director of the rescue group, said there were two explosions about an hour and a half apart, with the second explosion causing more damage.
The 10 rescued miners were in good physical condition and had been receiving food since Saturday after several days of living off nutrient solutions.
Twenty-two workers were trapped about 600 metres (2,000 feet) underground in the Hushan mine by the January 10 blast in Qixia, a major gold-producing region under the administration of Yantai in coastal Shandong province.
Later footage showed emergency workers lifting out the trapped miners who wore black masks "to protect their eyes", CCTV reported.
"It is now unclear when the rescuers will reach the Sixth Central Section where the missing miners are believed to be".
Another miner was found alive by rescuers as they attempted to reach the group.
How have the miners survived this long?
For a week, there was no sign of life. The note said 11 people were trapped in one section of the mine, one in another section and that 10 others were unaccounted for.
After that, the 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 on Thursday.
Chinese rescuers had only managed to make contact with 10 of the miners.
A communication line was established and food and medicine were lowered down through a narrow shaft.
Such protracted and expensive rescue efforts are relatively new in China's mining industry, which used to average 5,000 deaths per year. In September, at least 16 workers in southwestern China died after they became trapped underground in a coal mine and exposed to unsafe levels of carbon monoxide, state media reported.
