New Method of Computer Simulation for Shock Wave Created by Mined-out Area Roof Caving Based on Lattice-boltzmann
GENG Juan
Abstract：A new simulation model (WD2G9 model) for shock wave created by Mined-out Area roof caving based on lattice-boltzmann was put forward. In this simulation model, the process of the Mined-out Area roof caving is abstract to the process that the piston with total gravity promoting, Combined with D2Q9 model and D2G9 model, this paper discretes the compression shock wave created by the piston promoting in the discretiza?tion grids as the lattice-boltzmann model does, and wave as the time evolutes. In process of the simulation, we can visually watch the process of shock wave waving and the process of the air particle evolution, observe the change of the air viscosity and the press, this method provides a new way for the Mined-out Area roof caving pre?diction and prevention.
