Cellular automaton model for rock deformation in deep mining

According to discrete characteristics of deformation, an evolution model of deformation in mine rock-mass was built by using cellular automaton (CA). In order to measure the complex process of deformation in mine-rock body, the change probability of cellular rock and the influence coefficient were defined. Simulation tests were carried out and the experimental results were analyzed by use of R/S analysis. It is shown that discrete degree can be taken as the criterion of rock-mass stability.
