Two miners were missing and possibly trapped Tuesday hours after a wall collapsed onto heavy equipment at a surface coal mine in Maryland.
Rescue crews were on the scene at Tri Star Mining Inc. There were few details about the collapse.
"Our first priority is to rescue the trapped miners," said Amy Louviere, a spokeswoman for the Mine Safety and Health Administration in Washington.
Early reports pointed to a high wall collapse, she said. Louviere described the wall as being 100 feet (30.5 meters) to 125 feet (38 meters) high.

More than 5.8 million people voted for Nicholas Maduro at the presidential election in Venezuela. This is more than a quarter of registered voters. Why did those people vote for the man, who, as Western media write, took Venezuela to the brink of collapse?
It has long been understood that the West has been trying to subject Russian borders to total control. We have not seen such activity even during the Cold War
