摘要
基于有限差分数值计算方法,对某矿既有水平岩巷下方交错煤岩巷道掘进至交错位置附近迎头涌水现象进行数值模拟,综合交错巷道围岩的塑性区、位移场、应力场的分析,揭示了该交错巷道涌水的原因和机制,并结合实际工程情况,设计了采用注浆加固围岩堵水的工艺,并取得了良好的现场堵水效果,为类似工程的防水设计提供参考依据。
Water-burst from intersected coal and rock roadway face under rock roadway was simulated by finite difference numerical software. By analysis of plastic zone, displacement field, stress field, water-burst reason and mechanism was discovered. Technique of grunting reinforcement against water was designed and it made good water plugging effect and provided reference for similar engineering.
