Keep UP mining safety doubt-free

Michigan's Department of Environmental Quality stumbled in an uncharacteristic but worrisome way when it sidetracked, then retrieved, a two-part report it commissioned on a proposed underground mine near Marquette.

The first part of the report, by a mining engineer the DEQ hired as a consultant, raised doubt about whether Kennecott Mining Co.'s planned operation left a strong enough top layer to prevent a cave-in. The second part signed off on the mine's safety as long as mining activity is at least 360 feet below the surface.
