通过研究煤的自燃机理,得出了煤自燃的致灾机理及煤氧化自燃过程的表现特性,为煤自燃预测技术提供了理论依据。基于煤自燃特性,以温度、生成物等宏观量为检测指标,通过采用气体成分分析、测温、仿生气味监测、磁力预测等技术手段对煤自燃进行预测。为了提高对煤自燃预测的准确性并发展煤自燃机理,对煤氧化自燃过程中煤分子变化进行研究,以煤分子的微观变化为特性进行煤自燃预测具有一定的实际意义。
By studying the spontaneous combustion mechanism of coal, the mechanism of spontaneous combustion of coal and the characteristics of spontaneous combustion of coal are obtained, which provides a theoretical basis for coal spontaneous combustion prediction technology. Based on the spontaneous combustion characteristics of coal, the spontaneous combustion of coal was predicted by gas composition analysis, temperature monitoring, biomimetic odor monitoring, magnetic force prediction and other macroscopic parameters such as temperature and products. In order to improve the accuracy of predicting coal spontaneous combustion and develop spontaneous combustion mechanism, the molecular change of coal during spontaneous combustion of coal is studied. It is of practical significance to predict coal spontaneous combustion based on the microscopic changes of coal molecular.
