Twelve other miners were rescued from the mine after the blast occurred and two bodies of the deceased were recovered today, reported Xinhua News Agency.
The blast resulted in a tunnel collapse, which made it difficult for rescuers to reach the trapped mining workers.
Majority of the trapped were in their 40s, reported China Central Television.
Investigations are underway to identify the cause of the accident which is believed to have occurred due to a gas explosion.
The Dongfang Coal Mine had been ordered in June this year to cease production due to flood season; however, the operator ignored such orders.
This is the latest in a series of mine accidents in China this year, which left more than 100 people dead, International Business Times reported citing government estimates.
Last week, flooding at a coal mine in Jixi city of Heilongjiang province trapped 25 workers.
Although its safety record has been improving in recent years, China is said to host world’s high accident-prone mines.
