摘　　要：基于煤层底板突水的尖点突变特征 ,应用突变理论的方法 ,针对煤层底板突水预测指标监测信号 ,分析了单变量序列尖点突变模型及其稳定判据 ,提出了煤层底板突水的突变理论预测方法。实例表明 ,预测结果与现场工程实际情况相一致 。Based on cusp catastrophe characteristics of water inrush from coal floor, and a imed at the monitoring signal of predicting index for water inrush from coal flo or, the cusp catastrophe model of single variable series and its stable criterio n are analyzed by catastrophe theory. The predicting method based on catastrophe theory for water inrush from coal floor is proposed, and the practical predicti ng result conforms to on-site situation. Consequently it proves that this metho d is a new effective approach for predicting the water inrush from coal floor.
