Chinese mine boss drowns himself after deadly collapse

BEIJING -- The owner of a Chinese gypsum mine drowned Sunday after jumping into a well in an apparent suicide during rescue efforts for 17 workers trapped two days after the mine collapsed and killed one person, state media said.

Quoting a morning briefing by the rescue command center, state media said Ma Congbo, president of Yurong Commerce and Trade Ltd. Co., was assisting with rescue efforts Sunday morning when he jumped into a mine well and drowned.

Since the mine collapse Friday, rescuers have pulled 11 workers to safety and recovered one body.

Another 17 miners are yet to be found.

Gypsum is a soft sulfate mineral widely used in construction.

Chinese authorities typically have meted out harsh punishments, including jail sentences, to company management and local work-safety officials following major work-safety disasters.

Still, lack of regulatory oversight prevails, and cost-conscious management fails to pay enough heed to work safety.

The mine collapse came days after a landslide from a man-made pileup of construction waste in the southern city of Shenzhen killed one person and left another 75 missing and presumed dead.

Authorities have ruled the landslide was not a geological disaster but a work-safety incident, adding to China's list of man-made disasters in recent years.

In a rare move, Shenzhen's top officials, including its party chief and mayor, bowed deeply at a news conference as an apology.
