| 摘 要： | 基于潘家窑矿煤巷群的现场实际和拟建巷道的不同设计位置,建立了六种工况模型。分别采用FLAC3D数值模拟软件进行开挖模拟,并从位移、锚杆、锚索受力、塑性区分布等方面进行了分析,获取了对应工况下受力分布规律,为类似条件下的煤巷群围岩变形控制提供理论参考和技术借鉴。

| Abstract: | Based on field conditions of coal roadway groups in the panjiayao coal mine and different positions of proposed roadway,six working models were established.Stress distribution on the corresponding conditions was obtained through analysis under excavate simulation on displacement,stress of anchor and anchor cable,plastic zone distribution,etc,which provide the theory reference and technical reference for similar conditions. |
