The resolution, passed unanimously by a voice vote, recognizes the nine men by name, along with several others, for their "outstanding efforts in the aftermath" of the tragedies.

A similar measure, sponsored by Utah's House members, passed the House last week.

Sens. Bob Bennett and Orrin Hatch, both Republicans from Utah, also heralded the nine men and the others injured during the tragedy during floor speeches.

Bennett said the disaster has united the mining community and Utahns statewide "in mourning for those who had lost their lives in this tragic accident."

He added that Congress must do everything it can to see that "this kind of tragedy is reduced to the point that ultimately it ceases to be."
