With the drilling of another hole, the search for six missing miners moved Tuesday toward the back of a mine where officials hoped the men sought refuge in search of an air pocket.
Crews already have drilled two holes and fitted a camera down one of them, but they have yet to learn the coal miners' fate, eight days after the mine partly collapsed under the weight of a shifting mountain.
The camera's ghostly images revealed only one indication of a miner's presence: a tool bag for hammers, wrenches and chisels hanging from a post, 3.4 miles from the entrance and more than 1,800 feet underground.
"It indicates we're very close to where the miners were working," said Bob Murray, chief of Murray Energy Corp., co-owner and operator of the Crandall Canyon mine.
