摘要: 提出了一种基于Converse Earth平台对矿井突水漫延过程虚拟实现的方法,对突水漫延过程进行可视化表现,模拟突水水流在巷道中的漫延过程,分析突水水流在巷道下向蔓延及水位上向升涨等情况,实现了在巷道任一点的突水过程推演。在突水漫延过程中利用流体力学理论求出煤矿底板突水的突水量,计算突水水流在水平巷道的平均流速,引入当量长度求解水流通过不同巷道的时间,为规划逃生路径及制定应急救援决策提供了依据,并且对矿井突水过程进行了虚拟实现。Abstract: A method based on Converse Earth platform for virtual realization of mine water inrush process is proposed, which visualizes the process of water inrush. The water inrush process at any point of roadway is deduced by analyzing the water inrush flow spreading downward and water level rising. In the process of water inrush, the theory of fluid mechanics is used to determine the water inrush from the water in the coal floor, calculate the average flow velocity of the water in the horizontal roadway, and introduce the equivalent length to solve the time when the water flows through different lanes, to plan the escape route and formulate emergency rescue. The decision provides a basis for the virtual realization of the mine water inrush process.
