renewcomerLeave a comment

On October 1, 2022, a miner died while using a crane to remove a haul truck engine.  The auxiliary line broke, causing the hook and ball assembly to fall and strike the miner.

Best Practices: 

  • Make sure cranes have functional anti-two blocking devices to automatically shut off the crane when the rigging on the hoist line gets close to the sheave at the end of the crane boom.
  • Make sure miners stay clear of suspended loads and use taglines when necessary for steadying or guiding suspended loads.
  • Make sure miners conduct thorough pre-operational inspections of all machinery, equipment, and tools prior to use.

Additional Information: 

This is the 23rd fatality reported in 2022, and the eighth classified as “Machinery.”

On April 19, 2021, a 28 year old haul truck driver with 37 weeks and 5 days experience* stopped his haul truck in front of his personal vehicle to get his lunch at a crushed stone mine with 27 employees.*  While standing and eating his lunch, the haul truck rolled forward, pinning the miner between the haul truck and his personal truck.

Best Practices: 

  • Do not leave mobile equipment unattended unless the controls are placed in the park position and the brake is set.  NEVER use a steering column-mounted “dump brake” for parking.
  • When parking mobile equipment on a grade, chock the wheels or turn them into a bank.Maintain equipment braking systems in good repair and adjustment.
  • Position yourself in a safe location away from potential “danger-zone” areas.
  • Train miners to safely perform their tasks.

Additional Information: 

This is the eighth fatality reported in 2021, and the fourth classified as “Powered Haulage.” (*details added by safeminers.com from MSHA data.)

On October 14, 2020 (at a South Carolina mine with 49 employees*), a lead person (61 years old with 17 years experience*) was killed when his pickup truck was struck by a haul truck.

Best Practices: 

  • Install and maintain collision avoidance/warning systems.
  • Equip smaller vehicles with strobe lights and flags positioned high enough to be seen from the cabs of haulage trucks in all lighting conditions.
  • Establish and follow communication protocols that require verbal verification for all mobile equipment operators.
  • Design haul roads to minimize congested areas and maximize visibility.
  • Do not drive smaller vehicles in a large truck’s potential path.
  • Train miners on mobile traffic patterns and policies. Do not rely on training or other administrative controls alone to prevent powered haulage or other accidents.

Additional Information: 

This is the 20th fatality reported in 2020 and the fifth classified as “Powered Haulage.” (Italicized details added by safeminers.com)

2019 Fatality #12 / MNM #8

renewcomerLeave a comment

On Wednesday, July 17, 2019, a 32-year old general manager/owner was killed when he was struck by a hydraulic breaker. The victim and the excavator operator were in the process of positioning the excavator for a motor exchange when the hydraulic breaker attachment fell off the excavator and hit the victim.

Best Practices: 

  • Conduct adequate pre-operational checks and correct any defects affecting safety in a timely manner prior to operating mobile equipment.
  • Make sure machine implements are securely attached to prevent unintentional disconnection.
  • Stay clear of suspended loads and raised equipment.
  • Any repairs to equipment should be made to OEM specifications
  • Always position yourself in a safe location and away from potential “red-zone” areas.  Consult and follow the manufacturer’s recommended safe work procedures.
  • Train miners to recognize potential hazardous conditions and understand safe job procedures before beginning work.

On June 17, 2019, a front-end loader backed over a highwall, and the fall projected material from the loader bucket through the windshield. The operator was able to climb out of the cab and only suffered minor injuries. The operator was wearing a seat belt.

Best Practices: 

  • Always wear a seat belt when operating self-propelled mobile equipment.
  • Retrofit FELs, bulldozers, haul trucks, and other mobile equipment with operator’s seats that provide 3-point seat restraints, airbags, and other technologies to provide better protection to equipment operators. 
  • Always be attentive to changes in ground conditions and visibility when operating machinery.
  • Perform work a safe distance away from highwalls.
  • Maintain control of self-propelled mobile equipment while it is in motion.
  • Adequately task train mobile equipment operators.

On October 17, 2017, a miner was fatally injured while operating a bulldozer on a downward slope. While pushing overburden to a rock bench below the top of the pit, he was ejected from the cab and run over by the left track. The machine continued to tram over the edge of the 58′ highwall.

Best Practices

  • Always wear a seatbelt when operating mobile equipment.
  • Never jump from moving mobile equipment.
  • Ensure that persons are trained, including task-training, to understand the hazards associated with the work being performed.
  • Block the dozer against motion by setting the parking brake and lowering the blade to the ground before dismounting equipment.  Set the transmission lock lever to ensure the transmission is in neutral.
  • Establish and discuss safe work procedures before beginning work. Identify and control all hazards associated with the work to be performed and use methods to properly protect persons.
  • Do not place yourself in a position that will expose you to hazards while performing a task.
  • Maintain control of mobile equipment while it is in motion.
  • Maintain equipment braking systems in good repair and adjustment. Do not depend on hydraulic systems to hold mobile equipment stationary.

renewcomerLeave a comment

m12On September 8, 2016, a 58-year old Haul Truck Operator with 23 years of experience was killed at a granite mine.  The victim was operating a Caterpillar 773E haul truck and was returning to the pit to be loaded with shot rock. The truck veered from the right side of the haul road to the left and traveled over the berm at the top of the highwall.  The truck landed upside down approximately 150 feet below.  The victim was found outside the haul truck.

Best Practices

  • Always wear a seat belt when operating a haul truck or mobile equipment.
  • Conduct thorough, in depth task training to cover potential hazards.
  • Monitor employees regularly to ensure seat belts are worn when operating mobile equipment.
  • Emphasize that improperly worn seat belts can NOT provide the proper restraint to necessary to protect equipment operators in hazardous situations.
  • Conduct pre-operational checks to identify defects that may affect the safe operation of equipment before being placed into service.
  • Observe all speed limits, traffic rules, and ensure that grades on haulage roads are appropriate for haulage equipment being used. Maintain control and stay alert when operating mobile equipment.
  • Provide and maintain adequate berms and other barriers of mid-axle height.
  • Perform safety inspections that include braking systems and seat belts before operating equipment; promptly remove equipment from service if defects affecting safety are found.
