A mine owner has settled lawsuits filed by the families of miners and rescuers who were killed or injured by two cave-ins in 2007.

The settlement was signed Tuesday by lawyers for the defendants and family survivors of 12 men. The amount of the settlement was not disclosed.

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

The mine's owner, Utah American Energy Inc., says the settlement resolved costly and challenging technical issues and heads off an expensive trial.
