(CNN) -- Two miners died and several others were injured Friday when a wall collapsed at a Centertown, Kentucky, mine, the Ohio County sheriff said.
The two miners who died were driving in a truck near the wall when it collapsed. Their names have not been released, Sheriff David Thompson said.
Several other miners were injured when rock fell from what its known as a highwall, a vertical structure of coal and rock that is still being mined.
The incident happened at the Armstrong Coal Company's Equality Boot Mine, which has been open just over a year, Thompson said.
