Eleven others were rescued a day earlier after being trapped underground for two weeks at the gold mine in Shandong province. One person was still missing.
The cause of the accident at the mine, which was under construction, is being investigated.
The explosion on Jan. 10 released 70 tons of debris that blocked a shaft, disabling elevators and trapping workers underground.
Rescuers drilled parallel shafts to send down food and nutrients and eventually bring up the survivors on Sunday.

Search efforts will continue for the remaining miner until he is found, said Chen Fei, the mayor of Yantai city, where the mine is located.
“Until this worker is found, we will not give up,” he said at a news conference.
Chen and other officials involved in the rescue effort held a moment of silence for the victims, bowing their heads.
“Our hearts are deeply grieved. We express our profound condolences, and we express deep sympathies to the families of the victim,” he said.
Authorities have detained mine managers for delaying reporting the accident.
Such protracted and expensive rescue efforts are relatively new in China’s mining industry, which used to average 5,000 deaths per year.
Increased supervision has improved safety, although demand for coal and precious metals continues to prompt corner-cutting.
A new crackdown was ordered after two accidents in mountainous southwestern Chongqing last year killed 39 miners.
