After Upper Big Branch (Updated)

The West Virginia Board of Coal Mine Health and Safety is expected to propose several regulatory changes in the wake of the nation's worst coal mining disaster in 40 years, The Associated Press reports.

"Panel members say they hope to release proposed changes for mine rescue and ventilation of coal conveyer belts for public comment Wednesday," the article said. "They're also considering requiring mines to do more to control explosive levels of coal dust and to maintain methane detectors more often."

Update: The board sent out several proposed rules for public comment, including one that would require barometers at mine sites and another calling for regular checks of methane gas monitors. AP has details.
