【摘要】：为了有效预防神东矿区自燃火灾严重危害矿井安全开采的技术难题,应用傅利叶变换红外光谱技术系统地研究了煤在氧化自燃过程中生成的各种气体的红外光谱图谱,在研究煤在氧化自燃过程中不同温度下生成指标气体的规律的基础上,建立了判定煤炭自燃的预测预报模型；应用热重技术系统研究了神东矿区煤的自燃特性,应用着火活化能理论对神东矿区煤的自燃难易做出了科学判定,并以提高失水温度和增大着火活化能的数值作为标准,开发了适合神东矿区不同煤种及不同工作面的新型阻化剂。在哈拉沟矿开采过程中采用阻化剂喷洒技术有效防治了煤的自燃,而对于由于漏风等原因造成采空区煤炭自燃,则采取注氮与阻化防火相结合的自燃火灾防治技术。
[Abstract]:In order to effectively prevent coal spontaneous combustion from seriously harming mine safety mining, Fourier transform infrared spectroscopy (FTIR) was applied to study the infrared spectra of various gases produced by coal in the process of oxidation spontaneous combustion. On the basis of studying the law of coal producing index gas at different temperature in the process of oxidation spontaneous combustion, the prediction and prediction model of coal spontaneous combustion is established, and the characteristics of spontaneous combustion of coal in Shendong mining area are systematically studied by using thermogravimetric technique. Based on the theory of ignition activation energy, this paper makes a scientific judgement on the spontaneous combustion of coal in Shendong mining area, and regards increasing the temperature of water loss and increasing the value of ignition activation energy as the standard. A new type of resistance agent suitable for different coal types and different working faces in Shendong mining area has been developed. In the mining process of Haagou Mine, the technology of spraying inhibitor is used to prevent coal spontaneous combustion effectively, but for coal spontaneous combustion in goaf caused by air leakage, the combination of nitrogen injection and chemical and fire prevention is adopted to prevent and control the spontaneous combustion of coal.
