HUNTINGTON, Utah (AP) — A seismologist who detected ground tremors was the first to notify authorities of the cave-in that trapped six miners, even before mine officials called for an ambulance, according to 911 recordings.
The 911 tapes obtained Monday by The Associated Press showed that from the earliest moments scientists suspected the shaking came from a mine collapse, not a natural earthquake, as mine co-owner Bob Murray has maintained throughout the ordeal that has entered its fourth week.
“Just from the general character of the seismic event, it looks like it might be a coal-mining event,” Arabasz said on the tapes.
Also Monday, rescuers dug a seventh hole into the mine to make way for a robotic camera that will be used in a long-shot effort to find any sign of the missing men.
The first 911 call came at 3:47 a.m. from Arabasz in
“We had a big cave-in up here, and we are probably gonna need an ambulance. We’re not for sure yet because we haven’t heard from anybody in the section,” a voice identifying himself as Mark Toomer told a 911 dispatcher. “But we’re mostly likely going to need one up here.”
Arabasz told the dispatcher the seismic event registered as 4.0 magnitude at 2:48 a.m., and it was 3.1 miles west-southwest of the mine entrance. The severity of the event was later revised to 3.9 magnitude.
The six miners have not been heard from since the cave-in, which filled a mine shaft with rock and coal in the area where the men were working. No one knows whether the men survived the collapse.
Mine officials and federal regulators have worked unsuccessfully to locate the miners, drilling a half-dozen vertical holes into the mountain in hopes of finding signs of life.
Horizontal tunneling through the tons of debris inside was halted Aug. 16 after a second cave-in killed three rescuers, including a federal safety inspector, and injured six others.
It was unclear when drilling of the seventh hole would be finished. If the camera works, images were expected later Monday.
The camera is similar to one used to search the wreckage of the
It was not known for certain if the camera would fit into the narrow hole or move past rock and other debris before gaining access to the mine.
Also Monday, the state’s new Mine Safety Commission met for the first time. Gov. Jon Huntsman told the panel that he wanted members to determine whether
