A fall was discovered at B-2 from #3 Heading up to and including #5 Crosscut and outby on #4 Heading to #2 Crosscut. The fall occurred 1000' outby the face, and the area was bolted with 6' Super Twist bolts and 12' cable bolts. This made IE 2B2 inaccessible and blocked an alternate excapeway. A new escapeway was established.
