【摘要】 以新密某矿为工程背景,运用理论分析、有限元软件数值模拟等手段,研究了该矿承压水体上方断层附近掘进巷道的底板突水规律,确定了当掘进巷道掘至距断层30 m时,有突水危险性,从而为现场施工提供了量化指导。更多还原

【Abstract】 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.更多还原
