Prediction of coal and gas outburst based on catastrophe progression method

摘要: 针对煤与瓦斯突出发生的内在机理非常复杂、难以建立合适的多因素非线性预测模型的问题,提出了基于突变级数法的煤与瓦斯突出危险性预测方法。该方法选用典型突出矿井的煤与瓦斯突出实例作为学习样本,确定了不同冲击危险等级的突变级数,并应用于其他待判样本的预测。实际应用结果表明,该方法能较准确地反映煤与瓦斯突出的危险程度,预测精度较高。Abstract: In view of problem that inner mechanism of coal and gas outburst was very complex and it was difficult to establish an appropriate multivariate nonlinear prediction model, prediction method of coal and gas outburst based on catastrophe progression method was proposed. The method chooses coal and gas outburst instances of typical outburst mine as learning samples to determine catastrophe progression with different levels of impact risk, and uses them to predict the other samples. The actual application results show that the method can accurately reflect risk degree of coal and gas outburst and has high prediction accuracy.
