摘要
针对某矿煤层巷道锚固支护特点和流变特征,用FLAC3D软件进行了数值模拟分析。模拟结果表明,FLAC3D能够较好地模拟煤巷锚固煤(岩)体变形特征和锚杆(索)受力特征,可为煤巷锚固岩体支护方案的决策提供技术参考。
Based on the characteristics of anchor supporting and rheid in coal seam roadway of a colliery, the authors have made a numerical simulated analysis with FLAC3D Soft. Its results show that FLAC3D can simulate deformation characteristics of roadway anchor coal petrology and stress characteristics of bolting, which can provide technical reference for decision of roadway anchor supporting plans.
