On Monday, March 19,2007-Leadman called the surface office about 8am to inform me of a roof fall at the intersection of NE 10 @ U. This area had previously been closed off to access on 2-6-07. This area was not an active mining area. The roof fall was approximately 30' wide and 40' long forming a bowl in the roof roughly 20 feet high. MSHA was immediately called.
