A roof fall has occurred in the 3rd main east x-cut 133(103+20) in the neutral pillar line between entries #4-#5. The fall measured approximately 35'x19.5'x8' and was caused by a hidden slip in the mine roof. The area was supported by 6' tension rebar roof bolts and was mined in February 2009. There were no injuries and ventilation and the passage of men were not affected.
