【摘要】：针对综放孤岛工作面采空区漏风引起浮煤自燃的问题,以天池矿102综放孤岛工作面的应用为例,采用热重实验和热解动力学分析法进行FR-1阻化泡沫防灭火技术研究。对102工作面的煤样在阻化前后进行热重实验,通过热解动力学分析发现,阻化后进、回风巷煤样失水阶段的活化能分别增加了1.63倍和3.21倍;氧化增重阶段活化能分别增加了1.53倍和1.43倍,燃烧阶段活化能降低。现场应用发现,FR-1阻化泡沫具有良好的渗透性和堆积性,采空区的CO浓度不断下降并最终降到0ppm。研究结果表明,FR-1阻化泡沫能有效提高煤的失水活化能,具有良好的阻燃作用,能有效防止综放孤岛工作面的采空区自燃。
[Abstract]:Aiming at the problem of spontaneous combustion of floating coal caused by air leakage in goaf of fully mechanized longwall caving face, taking the application of 102 fully mechanized caving island face in Tianchi Mine as an example, the FR-1 technology of preventing and extinguishing fire with foam is studied by means of thermogravimetric experiment and pyrolysis dynamic analysis method. The thermogravimetric experiments were carried out on the coal samples of 102 working face before and after blocking. Through the kinetic analysis of pyrolysis, it was found that the activation energy of the coal samples at the stage of water loss in the backwind roadway was increased by 1.63 times and 3.21 times, respectively. The activation energy increased by 1.53 times and 1.43 times during oxidation and weight gain, respectively, and decreased in combustion stage. The field application shows that the FR-1 foam has good permeability and accumulation, and the CO concentration in the goaf decreases continuously and finally decreases to 0 ppm. The results show that FR-1 foams can effectively increase the activation energy of coal loss of water, have a good flame-retardant effect, and can effectively prevent spontaneous combustion in goaf of fully mechanized caving face.
