矿井阻化泡沫防火装置的应用研究

Application research on mine inhibitory foam fire prevention device

为解决晋华宫矿8105工作面采空区发生煤自燃时难灭火的问题,本文设计研发了胶体阻化泡沫防火装置,通过程序升温试验,验证了胶体阻化泡沫对煤自燃的影响,通过在8105工作面的现场应用,分析应用前后工作面气体变化情况。结果表明,在压注胶体阻化泡沫后,采空区内CO和CO_(2)的浓度值均减小,可以有效抑制煤自燃,对煤矿防火有显著效果。

In order to solve the problem that it is difficult to extinguish the fire when the coal spontaneous combustion occurs in the goaf of 8105 working face,a colloid inhibitor foam fire prevention device was designed and developed.The influence of colloid inhibitor foam on coal spontaneous combustion was verified by temperature programmed test.Through the field application of 8105 working face,the gas changes of working face before and after application were analyzed.The results show that the concentration values of CO and CO_(2)in the goaf are reduced after the injection of colloidal inhibition foam,which can effectively inhibit the spontaneous combustion of coal and have a significant effect on the fire prevention of coal mines.
