At approx. 11:38 am, a roof fall above the anchorage was discovered in the 4 North B entry return at spad No. 59+64. The travel way was blocked and ventilation was interrupted. The area had been mined in 2013 and was supported with 6 ft. fully grouted resin bolts. Plans were made to re-route the return and re-establish ventilation. There were no injuries or property damage.
