On Wednesday, February 21, 2018, a 38-year-old highwall mining machine operator, with 21 years of total mining experience, was electrocuted when he contacted an energized connection of a 7,200 volt electrical circuit.  The victim was found inside a transformer station troubleshooting and/or performing electrical work on the electrical system that supplies power to the mining machine.

Best Practices: 
  • Lock-Out and Tag-Out the electrical circuit yourself and NEVER rely on others to do this for you.
  • Follow these steps BEFORE entering an electrical enclosure or performing electrical work:
    1. Locate the circuit breaker or load break switch away from the enclosure and open it to de-energize the incoming power cable(s) or conductors.
    2. Locate the visual disconnect away from the enclosure and open it to provide visual evidence that the incoming power cable(s) or conductors have been de-energized.
    3. Lock-out and tag-out the visual disconnect.
    4. Ground the de-energized conductors.
  • Wear properly rated and well maintained electrical gloves when troubleshooting or testing energized circuits.  After the electrical problem has been found, follow the proper steps before performing electrical work
  • Use properly rated electrical meters and non-contact voltage testers to ensure electrical circuits have been de-energized.
  • Install warning labels on line side terminals of circuit breakers and switches stating that the terminal lugs remain energized when the circuit breaker or switch is open.
  • ​Electrical work must be performed by a qualified electrician or someone trained to do electrical work under the direct supervision of a qualified electrician.

renewcomerLeave a comment

On February 6, 2018, a 52-year-old electrician with 13 years of mining experience was fatally injured while working alone performing routine maintenance on a continuous mining machine.  A portion of rib, measuring 42 inches long, 28 inches high, and 14 inches thick, fell and struck the victim.  He was found between a coal rib and the continuous mining machine.

Best Practices: 
  • Be aware of potential hazards when working or traveling near mine ribs, especially when geologic conditions, or an increase in mining height, could cause roof or rib hazards.  Take additional safety precautions while working in these conditions.
  • Correct all hazardous conditions before allowing miners to work and travel in these areas.  Adequately support or scale any loose roof or rib material from a safe location.  Use a bar of suitable length and design when scaling.
  • Train all miners to conduct thorough examinations of the roof, face, and ribs in their work areas, including more frequent examinations when conditions change.
  • Install rib bolts with adequate surface area coverage, during the mining cycle, and in a consistent pattern for the best protection against rib falls.
  • Know and follow the approved roof control plan.  The roof control plan only contains minimum safety requirements.  Additional support may be required when roof or rib fractures, or other abnormalities are detected.

renewcomerLeave a comment

On December 30, 2017, an employee in a pickup truck approached the quarry loadout area to get the Front End Loader (FEL) operator for lunch. The FEL backed into the pickup, pushing it sideways and crushing the driver’s side of the pickup cab, trapping the victim inside the truck. The pickup truck caught fire and efforts by the FEL operator and a nearby contractor to put the fire out using fire extinguishers were not successful.

Best Practices

  • When approaching large mobile equipment, do not proceed until you communicate and verify with the equipment operator your planned movement and location.  Provide radio communication systems between vehicles and large mobile equipment.
  • Ensure all persons are trained to recognize workplace hazards – specifically, the limited visibility and blind areas inherent to operation of large equipment and the hazard of mobile equipment traveling near them.
  • Ensure, by signal or other means, that all persons are clear before moving equipment.
  • Minimize situations where smaller vehicles need to approach large front end loaders.
  • Do not drive or park smaller vehicles in mobile equipment’s potential path of movement.
  • Equip smaller vehicles with flags or strobe lights positioned high enough to be seen from the cabs of haulage trucks.
  • Install and maintain proximity detection or collision avoidance/warning systems and cameras.

On October 31, 2017, a 340-ton haul truck ran over a passenger van carrying nine miners. The driver of the van and the miner in the front seat were fatally injured. Of the remaining seven miners, one suffered a non-life threatening injury.

Best Practices

  • When approaching large mobile equipment, do not proceed until you communicate and verify with the equipment operator your planned movement and location.  Provide radio communication systems between vehicles and large mobile equipment.
  • Ensure, by signal or other means, that all persons are clear before moving equipment.
  • Minimize situations where smaller vehicles need to approach large haul trucks (e.g., arrange for haul truck drivers to have supplies available at the pre-shift meeting place, rather than delivering supplies to the truck).
  • Do not drive or park smaller vehicles in a large truck’s potential path of movement.
  • Equip smaller vehicles with flags or strobe lights positioned high enough to be seen from the cabs of haulage trucks.
  • Install and maintain proximity detection or collision avoidance/warning systems and cameras.
