2.9 Magnitude Earthquake has caused a Rock Explosion in a Chinese Mine Killing 4 and trapping a further 57 Miners - 4th Nov 2011

Rescuers were working Friday to try to save 57 miners who were trapped in a coal mine in central China after a rock explosion that followed a small earthquake, state media reported. Four miners were killed in the blast.

The accident in the coal mine in the city of Sanmenxia in Henan province occurred Thursday evening when 75 miners were working in the shaft, the official Xinhua News Agency said. Fourteen workers escaped.

At least 200 workers were digging a small rescue tunnel about 1,650 feet (500 meters) deep to try to reach the trapped miners, the People’s Daily newspaper’s website said.

The Qianqiu Coal Mine belongs to Yima Coal Group, a large state-owned coal company in Henan, the State Administration of Work Safety said on its website.

Xinhua said a magnitude-2.9 earthquake occurred to the east of Sanmenxia and that the rock explosion happened about 30 minutes later.

The phenomenon known as a “rock burst” occurs when settling layers of earth bear down on the walls of a mine and result in a sudden, catastrophic release of stored energy. Exploding pillars can turn chunks of rock or coal into deadly missiles, and the shock waves alone can be lethal.

The survival of the trapped miners depends on the intensity of the rock explosion and the rescuers’ ability to provide ventilation to them, a local official told The Associated Press. Read More
