  • Position yourself in a safe location away from potential “danger-zone” areas.
  • Train miners to safely perform their tasks.
  • Conduct equipment inspections and correct any defects affecting safety.

Additional Information: 

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

On December 14, 2020, two miners (age 27 & 41 with 22 weeks & 27 weeks experience*) died when a back failure occurred in a large four-way intersection (at a mine in Avery Island, LA with 200 employees*). The miners were pumping sealing grout in the intersection when blocks of salt and anhydrite fell from beneath a slickenside onto the miners.

Best Practices: 

  • In areas of excessive span or adverse geology:
    • Install supplemental ground support to control strata movement.
    • Install sag monitors or extensometers to detect ground movement or strata separation.
    • Drill and evaluate test holes for strata separation using a borescope or scratch test.
  • Use geologic hazard mapping to identify adverse conditions.
  • Be alert to any change of ground conditions.
  • Report hazardous or abnormal conditions.
  • Perform thorough workplace examinations where miners work or travel.
  • Identify and scale hazardous ground conditions from a safe location.
  • Train miners to recognize hazards and follow safe work practices, especially before they perform new tasks.

Additional Information: 

These are the 27th and 28th fatalities reported in 2020, and the second and third classified as “Fall of Roof or Back.” (*details added by safeminers.com from MSHA data)

On November 23, 2020 (at a mine in Houston, TX with 12 employees*), a (39 year old Maintenance Mechanic with 1 year 7 weeks experience*) was electrocuted while troubleshooting a disconnect box for the classifier drive motor. The victim had the electrical disconnect box open and the main power supply was not deenergized.

Best Practices: 

  • Ensure electrical circuit components are properly designed and installed by qualified electrical personnel.
  • Ensure electrical troubleshooting and work are performed by people with proper electrical qualifications. Positively identify the circuit on which work will be conducted.
  • Before performing electrical work, locate the visual disconnect away from an enclosure and open it, lock it, and tag it, to ensure all electrical components in the enclosure are de-energized. Verify by testing for voltage using properly rated test equipment.
  • Wear properly rated and well maintained personal protective equipment, including arc flash protection such as a hood, gloves, shirt and pants.
  • Train miners on safe work practices for electrical equipment and circuits.

Additional Information: 

This is the 26th fatality reported in 2020, and the second classified as “Electrical.”  (* Italicized details added by safeminers.com from MSHA data)

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 Nov. 8, 2020, (at a mine in Round Mountain NV with 864 employees*) a (58 year old*) bulldozer operator (with 41 years mining experience*) was killed when his bulldozer backed over the edge of a highwall (and came to rest over 300 feet downhill*).

Best Practices: 

•    Install and maintain lights to illuminate working places during the night and early morning hours.
•    Install berms, signs or devices to identify the edge of working benches and to allow equipment operators to maintain control of equipment.
•    Train equipment operators to identify dangerous conditions and to keep the dozer blade between the operator and the edge when near drop-offs.
•    Develop and enforce policies requiring safety belts when operating machinery.

Additional Information:

On Oct. 27, 2020, a miner (age 37 with 1 year 40 weeks experience*) was digging a hole (in an underground mine in Williamstown, PA with 8 employees*) to install a wooden post for roof control when a section of the roof fell on him.

Best Practices: 

  • Thoroughly examine the roof, face, and ribs where people will be working and traveling, including sound and vibration testing where applicable.
  • Scale loose roof and ribs from a safe location. Prevent access to hazardous areas until appropriate corrective measures can be taken.
  • Set temporary support before installing permanent support.
  • Be alert for changing conditions and report abnormal roof or rib conditions to mine management and other miners.
  • Know and follow the approved roof control plan and provide additional support when cracks or other abnormalities are detected. Remember, the approved roof control plan contains minimum requirements.
  • Propose revisions to the roof control plan to provide measures to control roof hazards.

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)
