Best Practices: 
  • Operate excavators with the cab perpendicular to, and away from, the highwall.
  • Design benches to safely accommodate the type of equipment used and include this in the Ground Control Plan.
  • Examine highwalls from as many perspectives as possible (bottom, sides, and top/crest) while maintaining the safety of the examiner(s). Look for signs of cracking or other geologic discontinuities.
  • Use auxiliary lighting during non-daylight hours to conduct highwall examinations and to illuminate active work areas.
  • Perform supplemental examinations of highwalls, banks, benches, and sloping terrain in the working area during inclement weather.
  • Immediately remove all personnel exposed to hazardous ground conditions, barricade, and/or post signs to prevent entry, and promptly correct the unsafe conditions.
  • Brief foremen and miners coming to work on any uncorrected hazardous conditions, and ensure the hazardous conditions are noted in the on-shift examination record book.
