Rescue workers have pulled 23 bodies from a mine in northern China wrecked by a gas explosion and are still searching for another 6 missing men, state media said on Friday.
The blast ripped through the shafts of the mine in Shaanxi province on Wednesday evening, when 36 miners were at work.
Seven escaped and the others were trapped, the official Xinhua agency said.
China's mining industry is the world's most dangerous.
A total of 3,786 coal miners died in gas blasts, flooding and other accidents last year as companies, often flouting safety regulations, rush to feed demand from a booming economy.
This mine was a state-owned local operation, with annual production capacity of 330,000 tones, the report said.
