Texto original en inglés de la MSHA

On August 3, 2015, Jason Potter, miner, age 26, was tramming a jumbo rock drill in reverse up a slope when a 13 ½ foot long drill steel came in contact with the rib wall and sprang back striking and killing the victim. The accident occurred due to management’s failure to ensure that loading and transporting of materials were done in a safe manner.

1. Management's policies and procedures were inadequate and failed to ensure that persons loaded and transported materials in a safe manner. The drill steel was transported on top of the jumbo drill and was allowed to extend 2.5 feet beyond the leading edge of the drill. Additionally, the drill steel was not secured in a manner that prevented the drill steel from sliding side to side. This caused the drill steel to strike the rib and then strike the miner.

   Acción correctiva: Management conducted training for all persons regarding the safe loading and transporting of materials.
