## Narrative

A roof fall was discovered in XC-39, between entries 1 & 2 in the LW-304 tailgate. This fall is an extension of one that occurred on 6/05/09. The fall was rib to rib, measuring approximately 19ft W by 9 ft H. The length could not be determined as it closed off access to this x-cut. The next isolation stopping was installed to remove this from the active workings.
