WASHINGTON (AP) -- The U.S. Senate has approved an amendment that would provide funding for a study into retreat mining.
The mining method has been blamed for the Crandall Canyon disaster in Utah in August, although the mine's operator denies retreat mining was a factor.
Still, Utah's two senators pushed for an amendment to an appropriations bill. The Senate passed it last night.
Senator Orrin Hatch says Crandall Canyon shows a need for improved mining safety practices.
Six miners were trapped when the central Utah mine shifted on Aug. 6. Ten days later, another collapse in the mine killed three rescue workers.
