Research of Forecasting of Spontaneous Combustion of Coal in Mined-out Area Based on Technology of Gas Chromatography

摘要: 根据煤自燃过程中各个阶段产生的不同标志性气体的特点,采用气相色谱仪对某矿采空区气样进行定性和定量分析,依据标志性气体的成分及含量变化情况预测采空区的煤自燃发火状况,为提前采取针对性的预防措施奠定了基础。

Abstract: According to the characteristics of different symbolic gases produced in different periods of spontaneous combustion of coal, gas chromatography was applied to make qualitative and quantitative analysis for gas samples in mined-out area of one coal mine, the components and the change of content of the symbolic gases were used to forecast condition of coal spontaneous combustion. It establishes a foundation for taking appropriate preventive measure in advance.
