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。
Taking Xinmi mine as the engineering background, the law of floor water inrush of roadway near the fault above the confined water in the mine was studied by means of theoretical analysis and numerical simulation of finite element software. When there is a risk of water inrush, thus providing quantitative guidance for on-site construction.
