Mine Flood Spreading Process and Its Virtual Realization

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.
