When a 15' cut from #4 to #3 entry holed out, the roof for 2 rows of bolts in #4 fell out, along with the unbolted cut. The approachs were cribbed off; at 4:50 pm the fall extended overriding the cribs, falling through the intersection of #4 entry, landing in the head of the cut. The fall area was bolted with 8' fully grouted bolts & 12' cable bolts.
