On June 3, 2016, a 24-year old haul truck operator, with 9 months of experience, and a 56-year old hydraulic excavator operator, with 6 years of experience, were killed at a sand and gravel operation. The two miners were working in a pit next to an abandoned roadway embankment, which partially bound an old pit. Waste clay and sand had been placed in the old pit for reclamation purposes. The embankment failed and the tailings and slurry engulfed both miners.
Best Practices
- Make sure that embankments containing ponds of water, tailings, processing waste, or other fluids are designed and constructed to be stable, and that mining operations are kept a safe distance away.
- Provide hazard training to all personnel working on or near an impoundment to recognize hazards associated with the impoundment, such as surface cracks or piping, and to recognize adverse conditions and environmental factors that can decrease stability before beginning work.
- Embankments adjoining workplaces and travelways should be examined weekly or more often if changing ground conditions warrant.
- Adverse weather, such as heavy rain, may introduce or increase hazardous conditions associated with impoundments, highwalls, and embankments. Workplace examinations should be increased when these hazards are present to recognize changing conditions.
- Before beginning work, conduct a workplace exam from as many perspectives as possible (bottom, sides, and top/crest) of ground conditions that could create a hazard to persons and repair, support or remove if found immediately. Correct hazardous conditions by working from a safe location.

On June 6, 2016, a 34-year-old contract laborer with 7 years of mining experience was fatally injured when a diesel-powered front-end loader fell on him. Working together, another miner and the victim lowered the bucket and put downward hydraulic pressure on the bucket to raise the middle of the loader. Both miners then crawled under the loader. The hydraulic pressure released, allowing the loader to lower, pinning both miners. A mine examiner, who was nearby, lowered the bucket again to raise the loader off the miners. One miner was freed and assisted in removing the unresponsive victim from under the loader. Cardiopulmonary resuscitation (CPR) was performed, but the victim could not be revived.
On May 10, 2016, a 46-year old maintenance man with 6 years of experience was fatally injured at a cement plant. The victim went to the top of the slurry tank to start the rake system. He fell 50 feet through a 3-foot by 4-foot opening in the walkway into the empty slurry tank below.
On April 11, 2016, a 61-year old dozer operator with 18 years of mining experience was fatally injured at a surface titanium ore mine. He had been leveling the haul roads into the pit with the dozer and was found lying approximately 30 feet in front of the dozer.
On April 9, 2016, a 25-year old plant operator with 4 years of mining experience was fatally injured at a surface copper ore mine. He was found unresponsive, kneeling with his face against a stainless steel flange that was connected to a high-density polyethylene pipe. The victim appeared to have received an electrical shock.
On March 22, 2016, a 42-year old lead man with 6 years of mining experience was fatally injured at a surface limestone mine when he was struck by fly rock from blasting operations. The lead man was parked in his pickup truck at a location to prevent others from accessing the blasting site. He was approximately 1,200 feet from the blast area.
On March 8, 2016, a 54-year old miner with 5 years of mining experience was killed at a surface sand and gravel operation. The miner backed his haul truck over a dump site and the driver was found at the bottom of the embankment, 60 feet below. The victim was found unresponsive and partially submerged in water. CPR was attempted, but the victim was not able to be resuscitated.
On Friday, March 25, 2016, a 48-year-old continuous mining machine operator, with 30 years of mining experience, was fatally injured when an overhanging section of a rock rib fell and pinned him against the haulage equipment. The fallen rib was approximately 44 feet long, 4 feet wide, and 2 feet thick. The victim was remotely operating a continuous mining machine that was being used to excavate material during the construction of a coal transfer shaft. The area where the accident occurred had a depth of cover of approximately 1,950 feet and a height of approximately 17 feet.
On Tuesday, January 19, 2016, a 36-year-old continuous mining machine operator was fatally injured when he was pinned between the conveyor boom of the remote controlled continuous mining machine and the coal rib while positioning the trailing cable. The victim had trammed the continuous mining machine back out of the No. 6 Face into the last open crosscut between No. 6 and No. 5 Entries. The victim had 5 years and 6 months of mining experience, with 1 year and 17 weeks experience as a continuous mining machine operator.
On January 16, 2016, a 31 year old continuous mining machine operator with 12 years of mining experience was fatally injured when a section of coal/rock rib measuring 4.5 feet long, 3 feet high, and 3 feet thick fell and pinned him to the mine floor. The victim was remotely operating the continuous miner in the number 2 entry of the advancing section when the accident occurred.
