Abstract：Fire fighting technology of nitrogen injection is one of the most effective technical measures in pre -venting 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 in-jection technology.Furthermore , it analyzes the fire control results in details.
Keywords：The"isolated island"in fully mechanized top coal caving facecoal spontaneous combustionni-trogen foam combinationintermittent type of nitrogen injection
