"The blast happened at 3.45pm and the last contact with any of the trapped miners was lost at 4.15pm, Mr Brownlee said."

This quote above worries me....each miner has 30 minutes personal air supply to give them enough time to reach an emergency air supply....communications were lost after 30 minutes.
