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 the factors that affect the coupling effect of bolt and cable support in deep mining roadways, taking the 11501 working face of Zhuji West Mine as the research background, the orthogonal support experiment was carried out to simulate the different support schemes by FLAC 3D numerical simulation. The results show that the influence of bolt length, bolt elastic modulus, bolt anchorage length and bolt pre-tightening force have a great influence on the bolt-rope coupling support.
