## Narrative

A roof fall occurred in the C10 heading between headings M1 and L4. The area was not a working area as it had been barricaded and signed from travel a week earlier due to observed conditions. The fall was approximately 90 ft long, 20 ft wide and up to 15 ft above the roof line at its furthest points. It is estimated that over 500 tons of material fell.
