At least 90 people have been killed after a gas explosion struck a coal mine in China, making it one of the country’s deadliest industrial disasters in recent years.

The explosion occurred inside the mine during operations, trapping workers underground and triggering a major emergency response. Rescue teams were deployed to search for survivors while medical crews treated injured workers at nearby hospitals.

Authorities launched an investigation into the cause of the blast, with early reports pointing to a possible gas buildup inside the mine. Chinese officials have ordered safety inspections and emergency reviews following the disaster.

Coal mining accidents have remained a serious issue in parts of China despite years of government promises to improve industrial safety standards. Dangerous working conditions, gas leaks, and poor enforcement of regulations have frequently been blamed for deadly incidents in the sector. The latest tragedy is expected to renew scrutiny over mine safety practices and worker protections across China’s mining industry as rescue and recovery operations continue.
