Xinxing mine explosion, Heilongjiang (2009)
A gas blast at the state-run Xinxing mine near Hegang killed 108 workers when 528 were underground. A preliminary probe blamed trapped pressurized gas and poor ventilation. Then-President Hu Jintao and Premier Wen Jiabao publicly directed the rescue.
The mine's director, vice director, and chief engineer were removed. Prosecutors opened a criminal negligence investigation.
Beijing tightened safety rules, shut thousands of smaller and illegal mines, and built a more centralized inspection regime that eventually became the National Mine Safety Administration in 2021.
Xinxing was the last Chinese mine disaster deadlier than Liushenyu. It is the template Beijing uses for executive prosecution and structural reform after a high-casualty blast.
