A Sanpete County man was killed at the Valley Camp coal mine after the brakes apparently failed on the utility vehicle he was driving to the shop for repair, authorities said.

Rodney J. Peterson, 49, Fairview, was killed about 4:15 p.m. Wednesday, Carbon County Sheriff's Deputy Scott Henrie said Thursday.Henrie said Peterson was using the small transport vehicle to enter the mine when he realized that the brakes were malfunctioning.

Peterson was traveling slow enough to use the emergency brake at the time. But after completing his assignment in the mine, Peterson was attempting to take the vehicle to a repair shop when the brakes completely failed.
