摘　　要：运用元胞自动机的演化建模方法构建深部采矿岩体的动态稳定性演化模型。定义岩体的工作状态变化概率和岩体完整性影响系数,创建了一种实现采矿岩体的动力学仿真模型。通过数字模拟实验,分析了岩体中不同状态下的元胞相互作用的关系,得到了以离散度作为岩体动态稳定性的度量指标。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.
