## Narrative

After taking the second lift (#42 on the pillar cut plan) a piece of draw rock fell cutting the #2 MRS cable. This delay allowed the roof to work, then fall on the #1 and #2 mobile roof supports before the cable could be repaired. The fall measured 18' by 28' long and was 4' to 5' in thickness.
