Numerical Simulation of Water Inrush in Excavation Roadway Near Faults

Taking one coal mine in Xinmi as engineering background, the paper studies floor water inrush laws of excavation roadway near fault above confined water with theoretical analysis, the finite element method and other means, when the excavation roadway excavates to 30 m away from the fault, there is the risk of water inrush, which provides quantitative guidance for construction site．
