Texto original en inglés de la MSHA

On May 22, 2023, at approximately 11:10 a.m., Darrell Huff, a 70 year-old stockpile driver with over 49 years of experience, died when the ground under his haul truck collapsed, causing the haul truck to overturn backwards, coming to rest at the base of the manufactured sand stockpile. The accident occurred because the mine operator did not: 1) establish mining methods to ensure stability of the dump site, 2) ensure miners dumped a safe distance back from the edge of the unstable area of the stockpile, 3) conduct adequate workplace examinations, and 4) ensure mobile equipment operators wore seat belts.

1. The mine operator did not establish mining methods to ensure stability of the dump site.

   Acción correctiva: The mine operator has abandoned the manufactured sand stockpile from future stockpile dumping. It will only be used to loadout customer trucks from the bottom of the pile. The mine operator also developed and implemented a new written procedure to ensure stability of dump sites that includes constructing stockpiles on a solid base, and prohibiting dumping above areas where material is being removed to load customer trucks. The mine operator trained all miners on this procedure.

2. The mine operator did not ensure miners dumped a safe distance back from the edge of the unstable area of the stockpile.

   Acción correctiva: The mine operator developed and implemented a new written procedure requiring miners to dump a safe distance back from the edge of stockpiles and the material to be pushed over the edge by a loader, bulldozer, or excavator. The mine operator trained all miners on the procedure.

3. The mine operator did not conduct adequate workplace examinations.

   Acción correctiva: The mine operator developed and implemented a new written procedure for conducting workplace examinations in around stockpiles. The mine operator trained miners responsible for conducting workplace examinations on the procedure.

4. The mine operator did not ensure mobile equipment operators wore seat belts.

   Acción correctiva: The mine operator retrained all miners in the requirement for seat belt usage under 30 CFR 56.14131(a).
