摘　　要：巷道交叉点处围岩应力复杂,在越南杨晖矿巷道交叉点一直采用U型钢支护,但面临很多问题,如通风受阻、通过能力受限,论文采用FLAC3D数值模拟软件,依据杨晖矿现场资料,模拟U型钢支护效果和锚杆支护效果,比较顶底板和两帮变形量,研究结果表明,锚杆支护可以应用该矿巷道交叉处,改进该矿的支护情况。The stress of surrounding rock at roadway intersection is complex.U-shaped steel support has been used at roadway intersection of Yanghui mine in Vietnam,but there are many problems,such as blocked ventilation and limited passing capacity.In this paper,FLAC 3D numerical simulation software is used to simulate the support effect of U-shaped steel and bolt based on the field data of Yanghui mine.The deformation of roof,floor and two sides are compared.The results show that bolt support is effective.The protection can be applied to the intersection of roadways in the mine to improve the support situation.
