基于一元线性回归法的瓦斯含量预测的修正

Revision of Methane Content Prediction Based on Linear Regression Method

通过研究一元线性回归分析法,发现运用埋深与瓦斯含量两者的一元线性回归预测的瓦斯含量很多低于实际值,存在安全隐患。为此提出了通过求解瓦斯含量的置信区间,把置信上限设为瓦斯含量的安全预测值,作为对传统的瓦斯含量预测值的修正,并通过在和成煤矿的工程实践,确认了这种方法的安全性和合理性。

It was found that methane content predicted by linear regression of buried depth and methane content was lower than practi -cal value.In order to eliminate the hidden danger , by resolving confidence interval of methane content , setting the upper limit of confi-dence interval as safe prediction value of methane content , which might be as amendment of traditional methane content prediction val -ue.Practice in Hecheng Colliery proved safety and rationality of this method .
