UPDATE 2:30pm: 14 News reports: "Armstrong Coal Company tells 14 News that the two miners trapped in Ohio Co. have died."
Preliminary reports show that two people employed by a blasting crew drove a truck near a high wall around 6:30 Friday morning.
When the rock fell, it trapped the men in the truck.
The Associated Press reports that rescuers are trying to contact the men who are currently trapped under a rock slide. Crews are working to remove the rubble with machinery, according to Ohio County Emergency Management Director Charles Shields.
14 News reports that rescue workers have reached the truck containing the two miners.
According to NBC News, the identity and condition of the men are not currently available.
Armstrong Coal Company's website describes Equality Boot mine, writing, "Armstrong's newest active mine, is a surface mine located near the city of Centertown in Ohio County, Kentucky that extracts steam coal from the West Kentucky #14, 13, 12 and 11 coal seams."
In June, three workers were trapped in another coal mine in Kentucky. All three were rescued from the mine the same day.
At another mine in Western Kentucky, two miners were killed in April 2010 after a roof collapsed. According to AP, the mine had "a long history of safety problems."
Earlier this week, the former security chief of the Upper Big Branch Mine in West Virginia was convicted of impeding the investigation of the worst U.S. coal mining disaster in decades. Last year, 29 miners were killed by an explosion at the Upper Big Branch mine.
