Abstract: For the actual situation of easy self-ignition seam at 11141 fully mechanized caving face in Tunbao Mine of Shenhua Xinjiang Energy Company, we propose the fire prevention and control technology measures under two kinds of situation about no signs of fire and signs of fire in the goaf. When the goaf has no signs of fire, we use the preventive technical measures about spontaneous combustion monitoring, sealing and blocking the air leakage channels, burying pipe to inject nitrogen in lower roadway, burying pipe to grout nitrogen in upper roadway and injecting two-phase foam. When the goaf has signs of fire, the comprehensive control measures about constructing airtight wall in both upper and lower roadway, injecting nitrogen by sealing, grouting to the gob by drilling holes are adopted, which ensures successful retreatment of Tunbao Mine 11141 working face.
