On Monday, June 6, 2016, at approximately 1:05 p.m., Robert E. Clark (victim), a 34-year-old contract laborer, was fatally injured when he was pinned between an underground diesel end loader and the mine floor. The victim and another miner had raised the end loader frame by tilting the bucket forward against the mine floor and crawled under the end loader to locate a hydraulic leak. A leak in the boom lift cylinder caused the bucket tilt cylinder to trip the stabilizer link which caused the machine to drop suddenly. The victim was trapped underneath the operator’s compartment. The accident occurred because the mine operator failed to ensure that the raised end loader had been securely blocked in position before performing work under it. An indirect cause was that the mine operator had not task trained miners on the hazards associated with the stabilizer link feature when using the end loader bucket to raise the machine. An additional indirect cause was that the mine operator failed to maintain the end loader in safe operating condition.

1. The mine operator failed to ensure that the raised end loader had been securely blocked in position before performing work under it.

   Acción correctiva: The mine operator developed a written blocking policy to comply with 30 CFR § 75.1726 when miners work on or under equipment or machinery that is in a raised position. Miners have been trained in this policy. This policy will be reviewed during new task training and be covered in annual refresher training.
