应用气体分析法预测预报煤自然发火

Applying Gas Analysis Method to Predict Coal Spontaneous Combustion

通过煤的升温氧化实验,分析煤氧化释放气体随煤温变化规律,确定煤自然发火预测预报的指标气体。运用灰色关联分析方法,对各主要指标气体进行了可信度分析。根据实验数据和分析结果,建立了煤自然发火的预报系统。

Through coal heating and oxidizing experiment, analysis was made on the gas release regularity of coal oxidation with the change of coal temperature and the indicator gases for predicting coal spontaneous combustion were determined. The reliability of the indicator gases in different oxidation phases was analyzed by means of gray correlation analysis. Based on the experimental data and analysis results, a prediction system for spontaneous combustion was designed.
