Best Practices

  • Conduct thorough pre-shift and on-shift examinations of the roof, face, and ribs. A thorough exam must be conducted before any work or travel is started in an area and thereafter as conditions warrant.
  • Support any loose roof or rib material adequately or scale loose material from a safe location before working or traveling in an area.
  • Danger-off areas that have hazardous roof or rib conditions until they are made safe.
  • Take additional safety precautions when mining heights increase because rib fall injury rates increase substantially as the mining height increases.
  • Use rib bolting to control unstable ribs. Rib bolts provide the best protection against rib falls and are most effective when installed on cycle and in a consistent pattern.
  • Be alert to changing geologic conditions which may affect roof/rib conditions.
  • Ensure that the Approved Roof Control Plan is followed and is suitable for the geologic conditions encountered.
  • Revise the Approved Roof Control Plan as needed when adverse conditions are encountered.
