MSHA reported that on May 22, a miner died at RiverStone Group’s Ralls County, Mo., operation when the haul truck he was operating overturned, when the edge of the bank at a dump point gave way. The haul truck landed on the roof of the cab.
This is the 20th fatality reported in 2023, and the fifth classified as “Powered Haulage.”
MSHA recommends the following best practices to avoid this type of accident:
- Conduct workplace and ground condition examinations before work begins in an area.
- Dump material from a safe location and push the material over the edge with a bulldozer.
- Ensure dump locations on unconsolidated material are properly designed, constructed and maintained.
- Construct substantial berms as a visual indicator to prevent overtravel. Clearly mark dump locations with reflectors and/or markers.
- Never load material from the toe of a stockpile that is directly below an active dump point. This may lead to an over steepened and unstable slope.
- Wear a seatbelt. Install advanced systems that restrain miners during roll-overs.
