Andrew Adams and AP Reporting Relatives of miners who died in the Crandall Canyon mine collapse are headed to Washington, D.C.
The family members are scheduled to testify at a U.S. House of Representatives committee meeting on Wednesday.
Relatives say they want changes in mine safety regulations so no other families have to go through the same experience.
Family members say the mine's owner and federal officials knew the techniques used to extract the coal from the Emery County mine weren't safe and were approved anyway.
"They [miners] trust the owners of the mine and MSHA to protect them and take all safety precautions with them, and I feel that both parties have dropped the ball," explained Kristen Kimber, whose ex-husband,Brandon, was killed during the rescue effort.
Six miners were lost when the mine collapsed on Aug. 6. Three rescuers died 10 days later in another collapse.
