On the I-6 retreat mining panel, a roof fall occurred in the #9 cross-cut of the #4 heading. The fall extended for approximately 60'. The area was originally supported with 8' torque-tension bolts spaced on a 4x4 pattern and 2 16' CC cable bolts installed every 8ft. Due to the location of the fall, the area was dangered off and supported, and the row of pillar blocks skipped.
