## Narrative

A methane ignition occurred in the 8th East development section.  The left side roof bolter operator drilled a hole to a depth of 17"" in the mine roof, when his drill steel plugged (wet drilling).  He was retracting the steel from the hole to clean the plugged steel, when the hot drill bit ignited a pocket of methane in the drill hole.
