A warning? Memo shows mine already had roof problems in March
Salt Lake Tribune Robert Gehrke August 12, 2007 06:53 PM
Operators at the Crandall Canyon mine experienced serious structural problems in the mine in March and entirely abandoned work in an area about 900 feet from where six miners remained trapped Saturday.
A memo obtained by The Salt Lake Tribune shows that mine owners were trying to work around "poor roof conditions" before halting mining of the northern tunnels in early March after a "large bump occurred . . . resulting in heavy damage" in those tunnels.
