Verona, KY (WCPO/CNN) - A worker at a limestone mine in northern Kentucky died in an underground truck accident.
It happened Tuesday afternoon, about 800 to 900 feet below the Earth's surface.
Officials say the 37-year-old woman was killed when she lost control of the truck she was driving.
It overturned, landing on top of her.
Rescue workers pronounced her dead at the scene.
A worker at the same mine was also killed in an accident back in 1999.
