US issues emergency order to suppress coal dust blasts. Probes of the Upper Big Branch coal mining disaster, which killed 29 people in April, are focusing on coal dust as the likely culprit.
The rescue team in the West Virginia coal mine disaster was called back Thursday morning – and hasn't yet reentered – because lingering gases 'have the potential to blow up in a heartbeat.'
Mining companies have been slow to adopt new safety requirements. Critics say the West Virginia disaster shows that Congress needs to step in. The industry says it needs clearer guidance.
