Dynamic visualization and prediction for water bursting on coal roof based on “three maps method”

  • The water inrush disaster in coal mine poses a great threat to production safety in the development of coal resources. However,there is no temporal and spatial expression on the process of water inrush disaster. In this paper,a 3D dynamic simulation was designed for water bursting on coal roof based on “ three maps method”. By constructing 3D geological models and “three maps”,the designs from various options were determined as the simulated areas for coal mining and water bursting sources,in order to correctly reflect the actual situations that may occur during the coal mining process. Therefore,the dynamic simulation of fractured zone and groundwater flow field is achieved through groundwater modeling,visualization preprocessing,and collision detection and response based on rigid body. In a case study at a mine in the midwest of Inner Mongolia autonomous region,the dynamic visualization and prediction were ap- plied based on data from the mine. It provides a new platform for understanding,analyzing and forecasting the water bursting on coal roof.
