renewcomerLeave a comment

On Feb. 22, 2021, a 26-year-old underground chute puller was fatally injured as a passenger of a rail-mounted locomotive when he was crushed between the deck of the locomotive and an overhead chute at a lead-zinc ore underground mine with 114 employees in Strawberry Plains, TN*.

Best Practices: 

  • Install controls such as rail stops at loading points, crossings, etc., where track equipment must stop. 
  • Install reflective signs or warning lights well in advance of low clearance areas to alert miners of the upcoming hazard.
  • Develop safe working procedures to avoid low clearance and pinch point areas.  Monitor workers to ensure these procedures are followed.
  • Always look in the direction the equipment is moving in, and keep all body parts within the operator’s compartment while a vehicle is moving.
  • Conduct proper travelway examinations to identify and mitigate the hazards presented by low clearances. 
  • Train all workers to recognize potential hazards and understand safe job procedures and tasks to eliminate hazards before beginning work.

Additional Information: 

This is the 4th fatality reported in 2021, and the third classified as “Powered Haulage.” *(details added by safeminers.com from MSHA data)

On February 8, 2021, a 38 year old ground man* was fatally injured when he became entangled in a fluted tail pulley while attempting to shovel under an adjacent fluted tail pulley at a limestone min in Potosi, MO with 12 employees*.

Best Practices: 

  • Design, install, and maintain area guards with signage and locks in addition to the physical barrier.  Find more information on area guarding at https://www.msha.gov/guarding-slide-presentation-guarding-conveyor-belts-metal-and-nonmetal-mines.
  • Design and maintain secure guards so miners can perform routine maintenance on belt conveyor systems without contacting moving machine parts.
  • Do not perform work on a belt conveyor until the power is off, locked out and tagged, and machinery components are blocked against motion.
  • Never clean pulleys or idlers manually while belt conveyors are operating.
  • Establish policies and procedures for conducting specific tasks on belt conveyors.
  • Ensure that people assigned to work on belt conveyors are task trained, understand the associated hazards, and demonstrate safe work procedures before beginning work.
  • Ensure all new miners receive new miner training and task training.

Additional Information: 

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

MNM Fatality – 1/19/21

renewcomerLeave a comment

On Jan. 19, 2021, a miner (a haul truck driver with 15y 42w mining experience, 07 42w at this task and mine in Orem, UT with 40 employees*) backed a haul truck to the edge of a dump point that was over steepened by a loader removing material at the bottom of the slope. When the edge of the bank failed, the haul truck traveled backwards and overturned, landing on the roof of the cab. The miner was fatally injured.

Best Practices: 

  • Always dump material in a safe location. If ground conditions aren’t reliable, dump loads a safe distance back and push the material over the edge.
  • Never load material from the toe directly below an active dump point. This may lead to an over steepened and unstable slope.
  • Never drive haul trucks beyond cracks on the top of the dump site.
  • Always construct substantial berms as a visual indicator to prevent overtravel. Clearly mark dump locations with reflectors and/or markers.
  • Always wear a seatbelt.
  • Install advanced systems that restrain miners during roll-overs.
  • Maintain communication between equipment operators and loaders.
  • Train miners to use safe dumping procedures and recognize dumping hazards such as material slides and other unsafe conditions.

Additional Information: 

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

Coal Fatality – 11/23/20

renewcomerLeave a comment

On Nov. 23, 2020, (at a mine in Dawes, WV with 154 employees*) a (20 year old*) miner (with 1 year and 8 weeks mining experience*) was fatally injured when the battery-powered scoop he was operating ran over a section of pipe in the roadway. The four-inch plastic pipe entered the operator’s compartment and struck him.

Best Practices: 

  • Conduct thorough examinations of roadways and remove material that could pose a hazard to equipment operators, passengers, or other miners.
  • Keep roadways free of excessive water, mud, and other conditions that reduce an equipment operator’s ability to control mobile equipment.
  • Secure loads on haulage vehicles to prevent them from falling off into roadways.
  • Install substantial guarding to prevent material from entering the operator compartment.
  • Establish safe operating procedures for mobile equipment and a maintenance schedule for roadways.

Additional Information: 

This is the 25th fatality reported in 2020, and the seventh classified as “Powered Haulage.” (* Italicized 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)
