The death toll from an explosion Aug 27 at a mine in Yingde, Guangdong province, reached 10 as a missing person was confirmed dead.

The explosion took place when workers unloaded explosives from the last of three trucks carrying more than 13 metric tons of explosives and detonators to a mine owned by a local cement company.

The cause of the explosion is still unknown.

Six tons of explosives and 460 detonators weren’t set off but experts are still examining them to see whether there is a risk of explosion.

The glass window of some houses in Yinghong town, separated by a river from the mine, were broken by the shock of the explosion. Nine local residents were slightly injured and the town suffered an economic loss of about 7 million yuan ($1.1 million).
