Best Practices

  • Always lock out, tag out, and test electrical equipment to verify all power has been de-energized prior to working on it.
  • Label power switches to show which units they control, unless identification can be made readily by location.
  • Leave protective covers in place until electrically powered equipment is de-energized.
  • Establish safe procedures before beginning work and discuss them with all miners involved in the task.
  • Always use properly rated tools and personal protective equipment when working with electricity.
  • Ensure that miners are properly task-trained for their assigned tasks.

Additional Information

This is the 23rd fatality reported in 2025, and the second classified as “Electrical.”

MNM Fatality – 9/8/25

A contract haul truck driver was injured while dumping a load of material at the top of a stockpile. The ground under the truck failed causing the truck to overturn onto its cab. The driver died later from his injuries.

Best Practices

  • Construct substantial berms, bumper blocks, safety hooks, or similar impeding devices at dumping locations where there is a hazard of overtravel or overturning.
  • Conduct workplace and ground condition examinations before beginning work in an area.
  • Always dump material from a stable and safe location.  If examinations indicate the ground conditions are not reliable, dump loads at a safe distance and push the material over the edge using a bulldozer.
  • Never load material from the toe of a stockpile that is below an active dump point.  This typically leads to a slope that is unstable and too steep.
  • Maintain stockpile slopes no steeper than the angle of repose.

Additional Information

This is the 22nd fatality reported in 2025, and the ninth classified as “Powered Haulage.”

MNM Fatality – 9/2/25

On September 2, 2025, a blaster was loading holes from the ground when a piece of rock fell from the roof and struck him. The blaster died from his injuries.

Best Practices

  • Be alert for changes in the roof, face, and ribs and take additional safety precautions when adverse conditions are encountered.
  • Install ground support where ground conditions, or mining experience in similar ground conditions in the mine, indicate it is necessary.
  • Scale loose roof and ribs from a safe location to maintain safe ground conditions.
  • Examine and test the roof, face, and ribs in areas where work is to be performed prior to work commencing, after blasting, and as ground conditions warrant during the work shift.
  • Train miners on how to identify hazardous roof conditions.

Additional Information

This is the 21st fatality reported in 2025, and the second classified as “Fall of Roof or Back.”
