Miner was squatting at the 8-bay looking at the screen. The rib blew out pushing miner against the 8-bay covering miner with rib rash. It took approx. 45 minutes to get the miner uncovered & out of the area. The distance between the rib & 8-bay prior to the incident was approx. 3 feet. The rib was supported with mesh & 4 foot bolts.
