Coal Fatality – 8/1/21

On August 1, 2021, a 38 year old utility person with 12 years 41 weeks experience drowned at a mine in Huntington, UT with 122 employees* during a flash flood while traveling in a personnel carrier to go to the mine portal.  The miner exited the personnel carrier as the floodwater engulfed the vehicle.  As the miner attempted to assist other miners, he was carried away by the floodwater. 

Best Practices: 

•    Monitor flash-flood watches and warnings and other adverse weather conditions, such as severe storm events, that could affect the safety of mine personnel.  Use NOAA Weather Radio or a smartphone app to monitor hazardous weather conditions in your area.
•    Establish policies and procedures to provide adequate warning to all mine personnel of ongoing weather conditions pertaining to flash floods and other adverse weather conditions.
•    Establish policies restricting access to areas likely, or known, to be affected by flash floods or other adverse weather conditions.  Do not travel across flooded roadways.
•    Properly design drainage systems, especially in areas where the terrain enhances water runoff and flooding.  Changes in a watershed, such as timbering or surface mining, can increase water runoff and flooding.
•    Examine drainage systems and features to ensure they are functioning and unobstructed.Additional Information: 

This is the 22nd fatality reported in 2021, and the first classified as “Inundation.” (*details added by safeminers.com from MSHA data.)

Fatality #7 & 8 for Metal/Nonmetal Mining 2016

m07-08On June 3, 2016, a 24-year old haul truck operator, with 9 months of experience, and a 56-year old hydraulic excavator operator, with 6 years of experience, were killed at a sand and gravel operation.  The two miners were working in a pit next to an abandoned roadway embankment, which partially bound an old pit.  Waste clay and sand had been placed in the old pit for reclamation purposes.  The embankment failed and the tailings and slurry engulfed both miners.

Best Practices

  • Make sure that embankments containing ponds of water, tailings, processing waste, or other fluids are designed and constructed to be stable, and that mining operations are kept a safe distance away.
  • Provide hazard training to all personnel working on or near an impoundment to recognize hazards associated with the impoundment, such as surface cracks or piping, and to recognize adverse conditions and environmental factors that can decrease stability before beginning work.
  • Embankments adjoining workplaces and travelways should be examined weekly or more often if changing ground conditions warrant.
  • Adverse weather, such as heavy rain, may introduce or increase hazardous conditions associated with impoundments, highwalls, and embankments. Workplace examinations should be increased when these hazards are present to recognize changing conditions.
  • Before beginning work, conduct a workplace exam from as many perspectives as possible (bottom, sides, and top/crest) of ground conditions that could create a hazard to persons and repair, support or remove if found immediately.  Correct hazardous conditions by working from a safe location.
