A gas explosion has killed 18
miners at an unlicensed pit in China's south-western province of Guizhou,
state media have reported.
Seven more miners were injured in the blast at the
privately-run Taojiawan coal mine in Liupanshui.
An investigation has been launched into the accident,
which brought the death toll for miners in China to more than 240 since
June and about 3,500 for the year so far.
Earlier this month, the authorities told 10,000
miners to leave their jobs in a crackdown against illegal gold mines
in northern Shanxi province following a string of high-profile disasters.
Correspondents say that central and local authorities
publicise their efforts to close unlicensed mines and those which fail
to pass safety tests.
But they add that many small mines ordered to close
manage to re-open because local governments are hungry for tax revenues.
