BEIJING (AP) " The Latest on an explosion in a western China coal mine (all times local):
Chinese state media say all 33 coal miners trapped underground in a gas explosion earlier this week have been found dead.
Two miners survived Monday's explosion but rescuers working around the clock found no others alive. All bodies have been recovered and rescuers were shown bowing their heads in memorial for the dead.
Gas explosions inside mines are often caused when a flame or electrical spark ignites gas leaking from the coal seam. Ventilation systems are supposed to prevent gas from becoming trapped.
The State Administration of Work Safety ordered an investigation, saying those responsible must be strictly punished. Local officials in Chongqing also ordered smaller mines to shut down temporarily.
China's mining industry has long been among the world's deadliest.

The death toll has risen by two to 15 following a gas explosion in western China, with 18 other miners still trapped.
It still wasn't known Tuesday afternoon if the 18 were alive more than a day after the blast ripped through the privately owned Jinshangou mine in the sprawling western Chongqing region. Just two miners were confirmed to have survived the blast.
Thirteen fatalities had been confirmed Tuesday morning. Later, two more bodies were recovered from among the 33 left in the shaft following the explosion, Xinhua News Agency reported.
Authorities said hundreds of rescuers were conducting an all-out search for those still trapped.

Xinhua had previously reported 15 deaths in the explosion, but said Tuesday that Chongqing's deputy mayor corrected previous reports from local coal mine safety authorities.
