Since CY 2012, falling rocks and materials from hazardous highwalls have resulted in 9 mining fatalities and 27 serious injuries. Develop and follow a plan for the safe control of all highwalls where miners work and travel in close proximity to the highwall. Train miners to …
Develop and follow a plan for the safe control of all highwalls where miners work and travel in close proximity to the highwall. Train miners to recognize highwall hazards. Conduct highwall examinations and assure hazards (loose rocks, overhangs, trees, etc.) are taken down or supported prior to work or travel near the highwall.
Three types of slope failure are the most serious hazards faced by surface miners: rock falls, plane shear, and rotational shear. Rock fall slope failures are caused by planes of weakness. The most common types of. faults, joints, and water pressure.
MSHA Issues Safety Alert About Highwalls - Mining Connection
Jan 30, 2023 · According to the Mine Safety and Health Administration (MSHA), since 2012, falling rocks and materials from hazardous highwalls have resulted in nine mining fatalities and 27 serious injuries. MSHA recommends the following best practices to avoid this type of accident:
splitting should be made a part of the mining method for final walls to reduce the potential for loose rock along the face. If a quarry has an exceptionally high face height, and if pre-splitting is a viable option, consider pre-splitting every shot. This is a potentially better alternative than manually scaling an exceptionally high face ...

Apr 4, 2023 · • Scale highwalls to eliminate hazards such as loose rocks or overhangs. Perform scaling from a position that will not expose miners to injury. Until hazards are corrected, place warning signs or barricades to prevent entry. • Restrict highwall height to allow available equipment to safely scale highwalls.
