On July 17, 2023, a miner died while performing repairs on a gyratory crusher. When a component was being suspended by a crane, a lifting eye welded to the component broke free striking the miner.

Best Practices

  • Ensure that all miners stay clear of stored energy while performing repairs. 
  • A certified welder should weld any lifting eye and ensure the welding rod is suitable for the materials joined together. 
  • Examine lifting equipment and connection points for cracks or deformation prior to lifting. 
  • Use low energy ropes and straps to minimize rebound effects when objects break.

Best Practices

  • Install berms, signs, or devices to identify the edge of benches.
  • Perform workplace examinations and correct hazardous conditions before beginning work and as ground conditions warrant. 
  • Train equipment operators to identify dangerous conditions and to keep the bulldozer blade between them and the edge near drop-offs.

On June 8, 2023, a miner died after climbing over the handrail onto a conveyor belt to gain access to a magnet belt that needed adjustment. When the miner stepped onto the magnet belt, the belt started, throwing the miner 16 feet to the ground below.

Best Practices

• De-energize, lock-out, tag-out, and block machinery against motion before performing repairs or maintenance on a belt conveyor.
• Install a system which provides visible or audible warning to warn miners that the conveyor will be started.
• Provide and maintain safe access to all workplaces and establish safe work procedures.
• Use fall protection when a fall hazard exists. Ensure fall protection has a suitable fall arrest and secure anchorage system, and that miners are properly trained.

On May 22, 2023, a miner died when the haul truck he was operating overturned, when the edge of the bank at a dump point gave way.  The haul truck landed on the roof of the cab. 

Best Practices

  • Conduct workplace and ground condition examinations before work begins in an area.
  • Dump material from a safe location and push the material over the edge with a bulldozer.
  • Ensure dump locations on unconsolidated material are properly designed, constructed, and maintained.   
  • Construct substantial berms as a visual indicator to prevent overtravel.  Clearly mark dump locations with reflectors and/or markers.
  • Never load material from the toe of a stockpile that is directly below an active dump point.  This may lead to an over steepened and unstable slope.
  • Wear a seatbelt.  Install advanced systems that restrain miners during roll-overs.

Additional Information

This is the 20th fatality reported in 2023, and the fifth classified as “Powered Haulage.”
