Power to the mine was disabled after the blaze and authorities said that there was air in some parts of the mine shaft.

It was not immediately clear if any casualties had been caused.

Accidents in mines are common in China, where there are poor safety regulations and inefficiencies.

Earlier this week 21 people were killed in two coal mine accidents in the southwest and centre of the country.

About 2,600 miners were killed nationwide last year, official statistics said.
