针对深井软岩巷道的支护问题,采用数值模拟方法对此问题进行了研究,具体通过应用数值计算软件建立相关地质模型,进行了相关计算与分析,研究在软岩巷道维修时,不同注浆材料对围岩巷道稳定性的影响作用和采动条件下,化学注浆材料联合锚注对围岩巷道的影响作用。 In order to solve the problem of supporting of deep soft rock roadway, the numerical simulation method is used to study the problem. The relevant geological model is established by numerical calculation software, and the relevant calculation and analysis are carried out. When the soft rock tunnel is repaired, different grouting The effect of material on the stability of surrounding rock roadway and the effect of the grouting material injected by chemical grouting on the surrounding rock roadway under mining conditions.
