On 10/3/08 the roof set down at 3+70 in the tailgate of 2B longwall. Face was at 3+90. Roof didn't fall but as a result the approved blockage plan was put into effect. At the time that this was called in to Safety Supervisor, it was not known if it was a fall or not so the agencies were called just in case. It was found that it was not a roof fall.
