Improving mine safety

The Herald Dispatch, Huntington, W.Va.: Four years ago, in the wake of a string of underground coal mining accidents, West Virginia and the federal government took a hard look at safety in the mines.

New federal regulations were passed to address a range of problems that surfaced from the Sago Mine disaster that left 12 miners dead.

More safety equipment is required underground, airtight emergency chambers have been created, better communication devices are being developed and expert teams must respond more quickly in the case on an emergency.

Many of those improved safety measures for trapped miners have been deployed, although some have hit snags along the way. But the explosion at the Upper Big Branch Mine raises a whole new set of issues about preventative measures.

Investigative team

The Mine Safety and Health Administration already has appointed a special team of investigators to study the explosion, congressional hearings are planned, and Gov. Joe Manchin also vows to hold hearings as he did with the Sago accident.
