对屯兰矿回采工作面和掘进工作面瓦斯涌出量进行趋势面法预测,建立了趋势面预测模型,并对观测值与趋势面模型中各项的密切程度进行检验,用F分布检验分析趋势面模型对原始数据的拟合显著性。研究表明:回采工作面瓦斯涌出量预测模型预测的准确性在95.08%以上,完全能够满足矿井实际瓦斯涌出精度要求。
The trend surface method was used to predict the gas emission from the coal mining face and heading face in Tunlan Mine. The trend surface prediction model was established and the closeness between the observed values and the trend surface model was tested. The F distribution test and analysis The fitting of the trend surface model to the raw data is significant. The research shows that the prediction accuracy of the gas emission prediction model at the working face is above 95.08%, which can fully meet the actual gas emission accuracy requirements of the mine.
