Taking the deep roadways in 5th coal mine,Pingdingshan Group Company of Coal Industry,as object of study,the effect of properties of surrounding rock on its displacement for deep roadway is evaluated by using the finite difference code FLAC3D,and the variations of displacement of surrounding rock under different internal friction angles and cohesive strengths of rock are presented.The results show that the internal friction angle of rock has importance affect on the displacement of surrounding rock for deep roadway when in-situ stress and support resistance all are certain.
