BEIJING - Chinese rescuers on Tuesday saved seven miners trapped for four days after a cave-in, the government said, in a rare victory for the country’s disaster-plagued mining industry.

The cave-in happened Saturday at the Aiyou Coal Mine in China’s northern Liaoning province, the official Xinhua News Agency said. Rescuers reached the miners around 3:50 a.m. (1950 GMT Monday) after digging a 29-meter (95-foot) tunnel, Xinhua said.

The men were rushed into ambulances and taken to the hospital for medical evaluation, it said. The report did not say what kind of condition they were in or how they survived so many days underground.

The accident is under investigation, the report said. Xinhua said the Aiyou mine is affiliated with the Fuxin Mining Group Co. Ltd, a huge, state-owned industrial group.

Another of Fuxin’s mines, the Sunjiawan colliery, was the site last year of the deadliest reported Chinese mine accident in six decades, when 214 coal miners died in an explosion.

Meanwhile, rescuers were searching Tuesday for five miners missing after a separate mine collapse in China’s northwest Shaanxi province that killed at least two people, Xinhua said. The cause of the collapse Monday at the Shuimogou mine in Shaanxi’s Zhenba county was under investigation, it said.

China’s coal mines are the world’s deadliest, with more than 5,000 fatalities a year in fires, gas leaks and other disasters that often are blamed on indifference to safety rules or lack of required equipment.
