| Abstract: | In order to reveal the evolving process of the meso-scale failure of rock and its mechanical features,a mechanical cellular automaton which can effectively simulate the evolving process of cell rock failure and its energy release rule was obtained in the paper based on the rule of dissipation and energy transfer and a 2-D particle element method was developed,which can effectively simulate the dynamic process of coal and rock and its energy variation.An improved Boltzmann method can realize the effective si... |
