| Abstract: | A model for the simulation of the dynamic stability in rock-mass mining, using Cellular Automata from complexity sciences, is presented in this paper. In order to measure the complex process in mine-rock body, the change probability of cellular rock and the influence coefficient were defined. The model is general and can predict the behavior of deep rock-mass, an algorithm for the simulation of deformation process has been developed, and the fractal in mining rock-mass based on numerical experiment and discrete degree is studied. The interaction among the deformation behavior, the whole stabilization in rock-mass as well as the basic factors are analyzed quantitatively. |
