摘　　要：应用Ｈａｋｅｎ的协同论思想，首次建立反映顶板活动演化过程的声发射序参量方程，详细研究了顶板从相对稳定、破裂扩展、显著活动、突变及又演化为相对稳定的非线性自组织演化过程，指出在突变临界状态，顶板活动的力学行为预测的不可靠性，这对围岩活动及非稳定性的预报研究具有重要参考价值。The acoustic order parameter equation of roof movement is built first according to the Haken′s synergetics, also non linear self organization evolution process, from relative stable state to fissure spreading and catastrophe and back to relative stable state, is studied in detail. It is put out that the prediction of mechanical action of roof movement at critical state is unreliable, which is valuable for the study of unstability prediction of surrounding rocks.
