- Make roof control plans that contain safety requirements. Rib support may be necessary when the mining height increases, when rock partings are present in the rib, or when encountering deeper cover.
- Mine operators must control roof and rib conditions. Plans should include provisions requiring that mine operators recognize adverse or changing roof and rib conditions.
- Be aware of potential hazards when working or traveling near mine ribs, especially when geologic conditions could cause rib hazards.
- Pay attention to deteriorating roof and rib conditions when working in, or traveling through, older areas of mines.
- Avoid areas of close clearance between ribs and equipment.
- Train all miners to conduct thorough examinations of the roof, face and ribs where miners will be working and traveling.
- Conduct frequent examinations in areas where mine conditions change.
- Correct all hazardous conditions before allowing miners to work or travel near them.
- Adequately support loose ribs or scale loose rib material from a safe location using a bar of suitable length and design.
- Install rib bolts on cycle, with adequate surface coverage, and in a consistent pattern.
