renewcomerLeave a comment

On October 11, 2010, a 56 year old roof bolting machine operator with 31 years mining experience was killed in a roof fall. The victim was standing beside the roof bolting machine when a portion of a rock brow fell from between the roof bolts and struck him. The rock was approximately 6 feet long and 3 feet wide, and varied in thickness from approximately 7 inches, up to 24 inches.

Best Practices

  • Remain alert for changing roof conditions, and remove hazards immediately.
  • Roof brows that are created by a sudden change in mining height can create unsafe roof conditions and may require removal and/or additional roof support.
  • Know and always follow your Approved Roof Control Plan.
  • Don’t leave freshly cut roof unbolted for long periods of time.
  • Use roof screen, large roof bolt plates, or other surface controls to prevent rocks from falling between supports.
  • Train all miners to identify unsafe roof conditions that are encountered daily.
  • Conduct thorough examinations in areas where miners will work or travel before and after work is completed.
  • Please see the following information related to roof bolter safety in the following links:

On Thursday, July 29, 2010, at approximately 11:55 a.m., the left side integral roof bolter operator on a continuous mining machine was fatally injured. The victim was struck with a portion of rib measuring approximately 276 inches long by 55 inches high and up to 16 inches thick. The accident occurred while cutting an overcast. The victim had installed one test bolt and was near the left rear bumper of the machine, when the accident occurred. The rock in the left rib sheared off pinning, the victim against the machine.

Best Practices
  • Develop a plan for cutting overcasts and train miners in the procedures and precautions.
  • Examine the roof and ribs frequently while working.
  • Take down or support any loose ribs or roof adequately before working or traveling in the affected area.
  • Be aware of changing roof and rib conditions, especially when working between the ribs and equipment.
  • Unless necessary, do not position yourself between any piece of machinery and the rib.
  • Where the mining process allows, remain within the confines of protective devices such as cabs, canopies and rib protectors whenever possible.
  • Install additional rib support prior to mining in areas where the roof or floor is cut above or below the coal seam, especially overcasts, loading points, etc.
