针对新河矿业730采区南部轨胶联络巷围岩松散破碎、变形严重情况，利用Comsol Multiphysics有限元分析软件探讨了不同注浆参数对浆液扩散的影响；并在此基础上，研究不同注浆锚索布置形式对注浆效果的影响。结果表明：浆液扩散半径会随着注浆压力增大、注浆时间延长而逐渐增大，每增大1 MPa注浆压力浆液扩散半径平均增长率为30.95%，每延长1 min注浆时间，浆液扩散半径平均增长率为25.67%；注浆锚索的布置形式决定了注浆加固圈的范围，当采用“六边形”布置方式时，其注浆加固圈范围相对较大，且顶板两侧不会出现漏浆的情况。基于数值模拟结果，确定了新河矿业南部轨胶联络巷锚注支护的注浆压力为4 MPa、注浆时间为8 min，注浆锚索布置方案为“六边形”式。工程应用表明：优化后的注浆参数有效地控制了巷道围岩的变形与破坏，取得了良好的工程效果，同时也为此类巷道的注浆加固提供了有效依据。

In view of the loose, broken and serious deformation of the surrounding rock of the connection roadway in the south of 730 mining area of Xinhe Mining Company, the influence of different grouting parameters on the slurry diffusion was discussed by using Comsol Multiphysics finite element analysis software; on this basis, the influence of different grouting anchor cable arrangement on grouting effect is studied. The results show that the slurry diffusion radius will gradually increase with the increase of grouting pressure and grouting time. The average growth rate of slurry diffusion radius is 30.95% for each increase of 1 MPa grouting pressure and 25.67% for each increase of 1 min grouting time; the layout of the grouting anchor cable determines the scope of the grouting reinforcement circle. When the “hexagon” layout is adopted, the scope of the grouting reinforcement circle is relatively large, and there will be no slurry leakage on both sides of the roof. Based on the numerical simulation results, it is determined that the grouting pressure of the bolt-grouting support of the connection roadway in the south of Xinhe Mining Company is 4 MPa, the grouting time is 8 min, and the grouting anchor cable arrangement scheme is “hexagon” type. The engineering application shows that the optimized grouting parameters effectively control the deformation and damage of the surrounding rock of the roadway, and obtain good engineering results, and also provide an effective basis for the grouting reinforcement of such roadway.
