Three-dimensional dynamic simulation modeling of water inrushes in underground mines

The architecture of three-dimensional dynamic simulation models for water inrush processes in underground mines was proposed by analyzing the influencing factors of spatial and temporal changes when water inrushes spread in roadways. A roadway space network system was developed through data modeling and regularization, transformation from arc lanes to straight lanes, and three-dimensional network processing of roadways. The path network of water inrush flowing through roadways was formed based on the path algorithm of water spreading downward and upward. The spread speed and time of water inrushes were resolved in combination with the hydraulic characteristics of water inrush flowing. In such a way, a three-dimensional dynamic simulation model was established which can simulate the spatial and temporal dynamics of water spread processes. A typical mine in China was exemplified to verify the feasibility and effectiveness of the established model.
