BEIJING—A deadly quarry collapse in northeast China this week reflects a surge in dangerous mining activity across the country as coal prices soar, following a government warning that the rally poses increased casualty risks.
The warning, in a report in early November, came as informal data have shown sharp increases in colliery casualties this year, with November the deadliest month so far.
On Tuesday, 22 workers were trapped when a shaft caved in at Qitaihe City Jingyou Coal Mine, a desolate outpost in China’s northeast, state-run Xinhua News Agency quoted rescue workers as saying on Wednesday. The cause wasn’t immediately known, nor was it clear whether any of those trapped had survived.
Last week, a coal-mine fire in neighboring Liaoning province killed 26 miners. The Work Safety Committee of the State Council, a government agency, also said it would step up surprise inspections, including at night, to counter “illegal practices” at mines that put lives at risk.
“As coal prices go up, mines tend to go beyond the usual safety limits to get at the more dangerous coal, and accidents increase,” said Keegan Elmer, a researcher for the Hong Kong-based watchdog China Labour Bulletin.
