摘　　要：分析了深部巷道围岩的变形与破坏机理,并以恒大煤矿2233工作面运输顺槽巷道为工程实例,采用FLAC^(3D)数值模拟软件分析不同锚杆支护参数对巷道围岩变形的影响,最终确定巷道围岩的最佳支护参数。研究结果表明,在巷道围岩支护参数中,锚杆长度在水平方向上的位移和应力变化均不明显,但在垂直方向上变化均较大,间距和锚杆预紧力对巷道变形与破坏的影响程度则相对较小。研究结果可以为后期研究巷道变形与灾变预警体系打下理论基础。Analyze the deformation and failure mechanism of the surrounding rock of deep tunnels,and takes the transportation channel tunnel of the 2233 working face of Hengda coal mine as an engineering example.FLAC^(3D) numerical simulation software is used to analyze the influence of different anchor rod support parameters on the deformation of the surrounding rock of the tunnel,and finally determine the optimal support parameters for the surrounding rock of the tunnel.The research results indicate that in the support parameters of tunnel surrounding rock,the displacement and stress changes of anchor rod length in the horizontal direction are not significant,but the changes in the vertical direction are relatively large.The influence of spacing and anchor pre tension on the deformation and failure of tunnels is relatively small.The research results can lay a theoretical foundation for later research on tunnel deformation and disaster warning systems.
