Application of fire fighting technology of nitrogen foam injection on fully mechanized coal face in Xin Yu mine coal
Abstract：Fire fighting technology of nitrogen injection is one of the most effective technical measures in preventing coal seam fire.However,nitrogen is light and loses easily.Regarding the practical situation on 5110 fully mechanized coal face of Xin Yu mine coal,this thesis analyzes the combination of nitrogen and foam for firefighting technology.It elaborates the nitrogen produce equipment,nitrogen injection way,and nitrogen injection technology.Furthermore,it analyzes the fire control results in details.
Keywords：The ＂isolated island＂ in fully mechanized top coal caving facecoal spontaneous combustionnitrogen foam combinationintermittent type of nitrogen injection
