摘　　要：应用FALC^(3D)数值模拟软件,对凤凰山矿15号煤层区段平巷道围岩变形特征进行了模拟研究,分析了区段平巷在掘进、上区段及下区段工作面回采过程中,上下区段平巷围岩变形特征,对于合理布置15号煤层区段巷道和选择有关参数具有指导意义。The deformation characteristics of surrounding rock of roadway in No.15 Coal Seam of Fenghuangshan Coal Mine were simulated by FALC^3D numerical simulation software.The deformationss characteristics of surrounding rock in upper and lower sections of roadway in the process of tunneling,mining in upper section and mining in lower section are analyzed.It has guiding significance for rational arrangement of laneway in section 15 of coal seam,and it has guiding significance to select relevant parameters.
