On 12/20/2011 an unintentional roof fall was discovered in the #4 entry of the #1 Southwest Panel between 49 and 50 break of the scoop road. On 04/19/2011 this area was showing some signs of top activity and we started adding extra support but did not get it completed. We were going to finish it on 04/20/2011. The fall measured approximately 70' long x 18' wide x 9' high.
