- Ensure that the approved roof control plan support provisions are suitable for the geological conditions at the mine and that the plan is followed.
- Ensure that the pillar dimensions and mining method are suitable for the conditions. OR, ensure that roof and rib control methods are adequate for the depth of cover and for the potential effects of any mines above or below active workings.
- Develop a map of geological features and anomalies to determine orientation as a means to predict when and where they will be encountered during mining, so additional roof support can focus on those areas.
- Conduct frequent and adequate examinations of roof, face, and ribs. Be alert for changing conditions. When hazardous conditions are detected, danger off access to the area until it is made safe for work and travel.
- Maintain proper entry widths and pillar dimensions.
- When gob falls have been delayed for periods that exceed routine intervals for the mining conditions, evaluate the area and consider evacuating miners and equipment to a safe area until the fall occurs.
