Simulation on Mine Water-inrush Characteristics of Cross Roadway Based on CFX
Mine water-inrush obeys Navier-Stokes turbulence flow in roadway. By tracking free surface of the airwater interface, the process of water flowing can be displayed. Transient simulations of mine water-inrush in 25s are performed respectively to cross roadway with different angles of 30°,45°,60°,75°and 90°, in which the CFX homogeneous free surface model and RNG k-e equation are used. Consequently, transient distribution of water-air free surface is displayed, and variation of pressure, velocity and mass flow rate with time in the lord lane and fork lane is achieved. According to the analysis, the flow characteristics and risks are analyzed in the process of mine water flowing in the cross roadways, and then corresponding security measures are proposed.
