CHARLESTON, W.Va. (AP) - The state Board of Coal Mine Health and
Safety plans to revisit West Virginia's regulations for sealing
abandoned sections of coal mines.
State law requires the board to review West Virginia's
regulations because the federal Mine Safety and Health
Administration changed its seal rules April 18.
The new rules stem from separate methane gas explosions in 2006
that killed 17 miners in West Virginia and Kentucky.
MSHA now requires seals to withstand at least 50 pounds of blast
pressure per square inch. MSHA also requires operators to monitor
for methane in sealed sections of mines if seals can't withstand
blasts of up to 120 psi.
The board is expected to review the regulations when it meets in
