摘　　要：自组织临界性理论为矿山动力灾害的防治开辟了新的途径,通过对岩石破裂的数值模拟,分析了岩石微破裂演化规律的自组织临界性及"雪崩"预兆性。依据自组织临界性,采用改进的B-G算法,探索了用状态预警和状态调节防治矿山动力灾害的研究方法。Self-organized criticality theory opens up a new way to prevent mine power disaster. The self-organized criticality of rock micro-fracture evolution laws and snow slide omen are analyzed by numer- ical simulation of rock fracture. According to the self-organized criticality and using the improved B-G algorithm, the method to prevent mine power disaster was studied by condition pre -warning and condition adjustment.
