摘要
自燃发火期是衡量煤自燃性风险的重要参数之一。认识煤炭自燃的条件以及自燃发展过程的影响因素、利用不同研究方法探究煤氧复合机理对于建立煤自然发火预测理论具有重要的意义。本论文通过理论分析与实验引用相结合方法。针对煤层自燃特点进行文献综述,建立煤自燃过程中标志性气体如一氧化碳、二氧化碳、甲烷、乙烯、乙炔等的浓度和热解温度。从指标气体理论分析出发,如何优选煤层自燃的指标气体,利用筛选出的指标气体对矿井的自燃防治进行监测方案设计,为矿井的早期预刚预报、并采取有针对性的预防措施提供依据。
Spontaneous combustion is one of the important parameters to measure the risk of coal spontaneous combustion. It is of great significance to explore the coal spontaneous combustion conditions and the influencing factors of the spontaneous combustion development process. It is of great significance to explore the coal and oxygen composite mechanism by using different research methods to establish the coal spontaneous combustion prediction theory. This paper combines theoretical analysis with experimental reference. The concentration of pyrolysis gases such as carbon monoxide, carbon dioxide, methane, ethylene, acetylene and the pyrolysis temperature during coal spontaneous combustion were established. Based on the analysis of the index gas theory, how to select the indicator gas of coal spontaneous combustion, and use the selected index gas to monitor the spontaneous combustion control of the mine, and provide the basis for the early pre - forecasting of the mine and the precautionary measures.
