Abstract: For coal and methane out-bursts frequently occurring in fault tectonic area in Jiulishan Mine of Henan Energy＆Chemical Group，stress distribution characteristics of fault tectonic of Jiulishan minefield was test and the impact of tectonic stress on coal and methane out-burst was analyzed.By arranging test points at different levels and applying stress relief method to field testing，geo-stress orientations and values at different levels were obtained.3-d geological model of large and medium-style faults was set up.Considering test geo-stress and applying FLAC^3Dsoftware，mine stress field and the stress distribution characteristic near faults zone was analyzed.On the basis of this，areas of stress concentration，stress relief and stress gradient within mine field were divided.By comparing division result and coal and methane out-burst areas，the relationship between faults stress distribution and coal and methane out-burst was analyzed，which provided reference for coal and methane out-burst prevention.
