Salt Lake City ? The owner and operator of Utah’s Crandall Canyon mine on Tuesday settled lawsuits filed by the families of the miners and rescuers who were killed or injured by two cave-ins in 2007.

The settlement — the largest in Utah mining history — was signed by lawyers for the defendants and the families of the 12 men who were killed or injured.

Six miners were trapped by a thunderous collapse at Crandall Canyon on Aug. 6, 2007. Another collapse 10 days later killed three rescuers, including a federal mining inspector, and injured three others.

Terms of the settlement were not disclosed, but lawyers on both sides said it exceeded the more than $20 million paid to families of 27 victims of a 1984 fire at the closed Wilberg mine in the same Utah coal district.
