  • The mechanism and damage evolution of high pressure water impaction on coal were numerically simulated using the method of coupling smoothed particle hydrodynamics(SPH) method with standard finite element method (FEM).The numerical computation model of high pressure water was a cylinder whose length is 5 mm and radius is 2 mm.According to numerical results, the coal damage evolution and stress wave propagation were studied.Meanwhile, the crushing strength of coal was obtained on foundation of numerical simulation.
