An unintentional roof fall occurred on the 5A travelroad at 52 crosscut on the 8th West panel. The fall measured 25 feet x 20 feet x 6 feet high. The fall had been bolted with 6 foot fully grouted roof bolts. The fall did not affect ventilation or cause personal injury. The fall was in the travelway so the secondary escapeway had to be re-routed.
