CHARLESTON, W.Va. -- The long-awaited deadline has arrived to improve safety in the nation's 540 underground coal mines by adding technology capable of tracking miners and communicating with them after a disaster.
Whether the mandate will immediately improve safety for the nation's 46,000 underground coal miners is unknown because it's uncertain how many mines installed everything they needed in time.
The most recent numbers from the federal Mine Safety and Health Administration show that as of April, 64 percent hadn't fully installed the required wireless equipment.
The equipment had better be there, MSHA Director Joe Main told The Associated Press.
"We're going to find out,'' Main said. "Mines are obligated to have their communications systems in and we're going to be applying the strength of the Mine Act.''
Main offered few specifics, saying only that communications and tracking equipment will be checked during regular inspections.
The deadline coincides with the fifth anniversary of landmark mine safety legislation passed after 12 miners died at the Sago Mine in Upshur County, followed by two more miners at the Aracoma Mine in Logan County, and five more at the Upper Darby Mine in Kentucky.
Some violations are likely to occur, in part because some are using technology that didn't exist in 2006 and only recently received approval for underground use, Main said.
"I will temper what I'm saying with this: We know that this is new technology, some of it just came through the pipelines in the last few months,'' he said. "There's going to be glitches.''
The National Mining Association estimates that companies have since spent $1 billion complying with the law.
The final piece is communications and tracking. Other requirements were completed long ago.
Mines, for instance, now must store two hours of breathable air per miner every 30 minutes along escape routes. They also must have airtight refuges capable of keeping trapped miners alive for 96 hours. The law also beefed up training requirements for mine rescue teams and miners and required mines to report accidents within 15 minutes. The number of rescue teams trained to enter mines and find and help miners has increased nearly 50 percent, Main said.
