On May 9, 2024, a miner died when he was pinned between the personnel lift that he was operating and the roof of a structure.  The miner was tramming the personnel lift from the basket to conduct a roller repair on an elevated belt conveyor.

Best Practices

  • Ensure miners maintain control of personnel lifts while in operation.
  • Use a spotter when moving mobile equipment in congested areas and around structures.
  • Monitor miners routinely to ensure miners follow safe work procedures while operating personnel lifts. 
  • Ensure miners are aware of their location in relation to nearby structures.
  • Conduct workplace examinations to identify and eliminate hazards before beginning work in an area.
  • Train miners in the safe performance of their tasks in accordance with the manufacturer’s manual.

Additional Information

This is the sixth fatality reported in 2024, and the fourth classified as “Powered Haulage.”

On May 8, 2024, a miner was electrocuted while unloading a roll of belt from a trailer.  The miner was performing rigging duties when the crane boom contacted an overhead high-voltage powerline.

Best Practices

  • Ensure that booms or masts of equipment are not operated within 10 feet of any energized overhead powerline.
  • Designate one person on the ground, located in a safe location, to give signals to the crane operator and watch placement and proximity of the boom.
  • Use non-conducting tag lines to steady loads when operating cranes where overhead power lines are present.
  • Post warning signs at all approaches to overhead powerlines; install barricades where necessary.

Additional Information

This is the fifth fatality reported in 2024, and the first classified as “Electrical.”

On April 15, 2024, a miner died when the tail section of a collapsible belt conveyor fell and pinned him between the tail section and middle section.  The miner was working as part of a crew to tear down the conveyor in preparation to be moved.

Best Practices

  • Block all equipment against hazardous motion before beginning work.
  • Stay clear of suspended loads.
  • Never enter or work in pinch points or Red Zones around equipment.
  • Identify hazards associated with the task, review those hazards with all miners involved, and implement measures to protect miners.
  • Train all miners in the safe performance of tasks.

Additional Information

This is the fourth fatality reported in 2024, and the third classified as “Powered Haulage.”

This fatality never had an alert posted individually by MSHA but was mentioned in this Electrical Saety Alert. The following text is from the Final Report.

On February 6, 2023, at approximately 3:45 p.m., Javier Regalado-Cano (Regalado), a 61 year-old haul truck driver with over a year of mining experience, was fatally injured when he received an electrical shock. While Regalado was operating a haul truck, he raised the bed of the haul truck into the energized 13,800-volt phase-to-phase power lines (power lines). Regalado exited the haul truck and extinguished a fire on the haul truck’s left rear dual tires. Regalado received an electrical shock when he contacted the energized haul truck while reentering it. 

The accident occurred because the mine operator did not: 1) install warning devices for the power lines, and 2) de-energize or take other precautionary measures when mobile equipment was operating near energized power lines.

On April 25, 2022, MSHA was informed of a miner’s death. MSHA’s initial findings indicated medical-related issues as the cause of death. Because of the circumstances surrounding the accident, MSHA referred the accident to the Agency’s Chargeability Review Committee (Committee). On March 28, 2024, the Committee determined that this death should be charged to the mining industry.

On April 25, 2022, co-workers found a maintenance worker lying face down in a pool of water.  The maintenance worker was using a water hose to wash out fine material that had gathered under a tail pulley.

Best Practices

  • Maintain workplaces in a clean and dry condition when possible. 
  • Where wet processes are used, maintain drainage platforms, mats, or other dry standing places.
  • Ensure that miners have communication systems available when assigned to work alone.
  • Routinely check in on miners working alone.
  • Conduct workplace examinations before work begins in an area.

Additional Information

This is the 30th fatality reported in 2022, and the third classified as “Drowning.”

MNM Fatality – 1/2/24

On January 2, 2024, the driver of an over the road tractor-trailer haul truck died when the trailer tipped over onto the cab of the tractor. The driver was dumping part of the load of gravel from the trailer. Between 2018 and 2024, mine operators reported 14 injury accidents where over the road trucks tipped or rolled over while dumping. During the same period, miners were also injured when 28 off-road mine haul trucks tipped or rolled over. 

Best Practices

  • Dump only on level surfaces, free of spillage. Make sure elevated dump sites are substantial and equipped with adequate dump point restraints.
  •  Keep your truck and trailer in a straight line when backing up and never move faster than walking speed.
  • Avoid dumping in high or gusty wind conditions.
  • Stay in the cab with your seatbelt on during the dumping process. Never attempt to exit or jump from an overturning truck.
  • After dumping, remove any compacted material before reloading the truck.
  • Evenly distribute the load and use antifreeze in cold weather to prevent material from freezing and sticking in the truck bed.
  • Never overload trucks or trailers.

  • Examine work areas before and during the shift for hazards. 
  • Ensure that blocking material is competent, substantial, and adequate to stabilize the load. 
  • Train miners in safe work procedures and hazard recognition. Monitor personnel routinely to ensure they follow safe work procedures.

On January 29, 2024, a miner died when his haul truck traveled over the edge of a stockpile and overturned.

Best Practices

  • Examine dumping locations before work begins to identify hazardous conditions, especially after heavy rain, or other significant weather changes.
  • Always wear a seatbelt.
  • Provide adequate illumination at dumping locations.
  • Ensure dumping locations are properly designed, constructed, and maintained.
  • Dump material at a safe distance from the edge and push the material over the edge with a bulldozer.
  • Construct substantial berms as a visual indicator to prevent overtravel at dumping locations.  Clearly mark dumping locations with reflectors and/or markers.
  • Do not remove material from the toe of stockpiles when it would create instability at dumping locations.

Additional Information

This is the second fatality reported in 2024, and the second classified as “Powered Haulage”.
