## Narrative

A Roof Fall occurred in 2nd West @ the Face-Intersection of XC #40 in Entry #4. It appears to be about 7' height, 19' wide and 35' long. No one was injured or entrapped and no ventilation was interrupted. Preliminary diagnoses is that vertical cracks in the strata, parallel with the crosscuts, allowed the strata to fail. New Primary & Supplemental Support has been installed.
