突变理论方法预测煤层底板突水危险性

Prediction of water inrush risk in coal seam floor by catastrophe theory

应用一种新兴的理论——突变理论,在尖点突变模型的基础上,对某煤矿下组煤煤层底板突水的危险性进行预测,得出了煤层煤底板突水的危险性分区图,其结果与突水系数法较一致。

The article used another emerging theory basis of catastrophe theory,cusp catastrophe model based on the previous studies on the prediction of water inrush danger of a coal seam floor,the lower group coal floor water inrush risk zoning map,and obtained is consistent with the conclusion that the water inrush coefficient.
