## Narrative

A dome shaped unplanned roof fall measuring approximately 20 ft. long by 16 ft. wide by up to 6 ft. above anchorage occurred in the East Mains 3 #2 entry at 23 wall. The roof fall is in an area of high humidity in a 4-way intersection. The humidity most likely caused the original 6' grade 40 bolts to weather and weaken over time.
