Best Practices

  • Ensure that the approved Roof Control Plan support provisions are suitable for the geological conditions at the mine and that the plan is followed.
  • Develop a map of geologic features, so additional 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.
  • Develop a safe procedure to align Mobile Roof Supports with the lift being mined.
  • Install and examine test holes regularly for changes in roof strata.
  • Take additional measures when hazards associated with draw rock are encountered, such as mining shorter cuts and decreasing roof bolt spacing.
  • When joints are encountered, install adequate supplemental support.
