| 摘 要： | 根据巷道围岩超过强度峰值后的变形是其强度不断降低的平衡过程，分析了滞后注浆巷道稳定技术的原理考虑实现新平衡及其所需的时间提前量，结合巷道变形（或破碎圈）发展规律的经验关系，给出注浆加固巷道稳定技术的滞后时间参数确定方法其结果在经验的最佳滞后时间范围上限，较国外方法有更合理之处

| Abstract: | The principle for stabilizing the roadway by delayed grouting is described based on the balance process of the rocks of roadway after the peak strength.A method for determination of the parameter of the lagging time,is given by taking into consideration of new balance and the lead time required.The calculated data is within the upper limit of the optimal lagging time,which is more reasonable than the method used abroad. |

| Keywords: | consolidation of rock by grouting stability analysis lagging time |
