摘　　要：为了研究深部回采巷道锚杆锚索支护耦合效果的影响因素,以朱集西矿11501工作面为研究背景,采用正交实验,利用FLAC^(3D)数值模拟对不同支护方案进行模拟。研究结果表明:锚杆长度、锚杆弹性模量、锚杆锚固长度、锚杆预紧力4个因素对锚杆锚索支护耦合影响较大。In order to study influencing factors of bolt and anchor cable coupling support in deep mining roadway, taking Zhujixi mine 11501 working face as the research background, adopts orthogonal experiment, and FLAC3D numerical simulation to simulate the different support parameters. The research results show that four factors have large influence on coupling support of anchor cable, such as bolt length, elastic modulus of anchor bolt, anchor length, and bolt pre tightening force.
