On December 22, 2025, a contractor died after receiving burns from a pressurized hydraulic line that ruptured and caught fire.  The contractor was cutting shims from a cone crusher with a torch.

Best Practices

  • Never apply heat to or near pressurized hydraulic lines.
  • Never apply heat to components when flammable, combustible, or explosive materials are present.
  • Protect and/or relocate hydraulic lines to prevent physical damage.
  • Examine all components and surrounding areas before applying heat, cutting or welding. Conduct daily inspections of hydraulic equipment, hoses, and connections for leaks, wear, or damage.
  • Always use proper protective equipment for the task.

Additional Information

This is the 33rd fatality reported in 2025, and the first classified as “Exploding Vessels under Pressure.”

On December 18, 2025, a miner died after a tractor pinned him against the rib.

Best Practices

  • Stay out of “red zones” and pinch point areas.

On December 10, 2025, two contractors died when the dragline they were operating slid into a water-filled pit.

Best Practices

  • Establish mining methods based on geological conditions such as soil stability subsurface cavities.
  • Evaluate all pit, highwall, slope, and bank conditions at least daily or more often, if necessary, to protect the health and safety of the miners. Be especially vigilant after each rain, freeze, or thaw.
  • Conduct effective workplace examinations in areas where miners are working and traveling. Identify and correct all hazards.
  • Train miners on equipment risks and to recognize potential hazards that can decrease bank and slope stability.

Additional Information

These are the 30th and 31st fatalities reported in 2025, and the fifth and sixth classified as “Machinery.”

On November 22, 2025, a plant operator died after he was struck and engulfed by falling material at a salt silo discharge outlet. He was attempting to clear a blockage with his head and arm inside the silo access door.

Best Practices

  • Equip bins and hoppers with mechanical devices such as vibrating shakers or air cannons to loosen blockages or provide other effective means so miners are not exposed to caving or sliding materials.
  • Ensure miners are positioned in a safe location and away from potential hazards.
  • Make sure miners working under hazardous conditions can be seen, heard, and able to communicate with others.
  • Examine working places to identify the potential for falling or sliding materials prior to allowing access to areas in or around bins and hoppers.
  • Before blocked bins and hoppers are cleared, train miners to recognize and safely remove all potential hazards.

Additional Information

This is the 29th fatality reported in 2025, and the first classified as “Handling Material.”

On November 8, 2025, a section foreman died after a mine was inundated with water from an adjacent abandoned mine. The foreman was found on November 13, 2025.

Best Practices

  • Determine the location of abandoned mine workings using signed maps and local sources. Abandoned mines are a major flood hazard.
  • Provide sufficient barrier pillars. Evaluate interburden thickness and compare mine surveys from a common baseline.
  • Use directional, long-hole drilling to ensure adequate barriers around mining areas.
  • If necessary, submit permits for “operations under water.”

Additional Information

This is the 28th fatality reported in 2025, and the first classified as “Inundation”.

On November 6, 2025, a miner died when the scoop he was operating was struck by the lead locomotive of a supply trip.

Best Practices

  • Operate mobile equipment at safe speeds appropriate for the grade, load, and track conditions. Select the proper gear before descending grades to maintain positive control.
  • Conduct thorough pre-operational examinations of all mobile equipment. Test brake systems, sanders, and communication devices before use and ensure they work properly.
  • Establish and follow communication protocols that require verification for all mobile equipment operators.
  • Make sure miners communicate their location and intended movements with the dispatcher.

Additional Information

This is the 27th fatality reported in 2025, and the 12th classified as “Powered Haulage.”

On October 16, 2025, a miner was performing work from an elevated platform when they fell approximately 30 feet. The miner died from his injuries.

Best Practices

  • Provide safe access to all work areas by installing handrails, guarding, or the use of fall protection equipment where there is a risk of miners falling.
  • Provide and ensure proper use of fall protection when a fall hazard exists.  Ensure fall protection has a suitable fall arrest and secure anchorage system.
  • Identify risks and eliminate or control them before beginning activities.
  • Conduct workplace examinations to identify conditions that may adversely affect the safety or health of miners.

Additional Information

This is the 25th fatality reported in 2025, and the first classified as “Slip or Fall of Person.”

  • 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.”

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.”
