Miner Injured by Roof Fall from Between Bolts
On February 12, 2005 at approximately 3:15 p.m., a fall-of-roof injury occurred at an underground coal mine in District 8. After the continuous mining machine operator had completed the cut in the No. 1 entry, he backed the machine partially into the adjoining crosscut. He then shut off the machine in preparation to move the trailing cable. As the machine operator traveled to a location between the machine and the coal rib, a piece of rock fell out from between the bolts and struck him. The piece of rock measured approximately 10.5-feet long by 3-feet wide by 5-inches thick. The operator sustained spinal injuries and contusions.
- Examine the roof closely and scale down any loose roof
- Install wooden headers, larger plates, straps, or screen wire mesh to help control ...the immediate roof.
- Decrease bolt spacing when needed
