Abstract: Because of the high stress characteristics, after entered into stage of deep roadway driving of Qingcaichong Mine of Mine Company of Kailin Group, deformation and anchor shotcrete layer collapse phenomenon were serious after roadway driving supporting, through finite element numerical calculation was done on roadway of drivingthree-element arch section of different middle part, analyzed the stress characteristics of different tunnelling footage, provided technical support for deep roadway driving.

Key words: Deep three-element arch roadway, Stress characteristics, Numerical calculation
