摘　　要：开磷矿业总公司青菜冲矿进入深部开采,深部巷道掘进后,由于其高应力特征,巷道掘进支护后变形和锚喷层垮落现象极其严重,通过对不同中段掘进三心拱断面的巷道进行有限元数值计算,分析其不同掘进深度的应力特征,为深部巷道掘进提供了技术支撑。Because of the high stress characteristics, after entered into stage of deep roadway driving of Qingcaichong Mine of Mine Company of Kailin Grout）, deformation and anchor shoterete layer collapse phenomenon were serious after roadway driving supporting, through finite element numerical calculation was done on roadway of driving three-element arch section of different middle part, analyzed the stress characteristics of different tunnelling footage, provided technical support for deep roadway driving.

关 键 词：深部三心拱巷道 应力特征 数值计算
