摘　　要：在等量的煤样中添加最佳配比的黄泥浆添加凝胶材料及用于对比分析的其他固液两态防灭火材料,根据煤自燃的机理以及相关的物理、化学原理,通过计算机对相关数据进行计算和处理,对比煤样自燃性测试结果中相关参数的变化情况,考察对比最佳配比的黄泥浆添加凝胶材料和其他固液防灭火材料在抑制煤炭氧化自燃过程的差异,验证其抑制煤炭自燃效果的能力。In this paper, the gel material and the other solid-liquid two-state fire-extinguishing materials for comparative analysis are added by adding the best proportion of yellow mud slurry to the same amount of coal samples, and then according to the mechanism of coal spontaneous combustion and related physical and chemical principles. The relevant data were calculated and processed by computer, and the changes of relevant parameters in the spontaneous combustion test results of coal samples were compared. The best proportion of yellow mud slurry added gel materials and other solid-liquid fire-extinguishing materials were investigated to inhibit the spontaneous combustion of coal. The difference is verified by its ability to suppress the spontaneous combustion effect of coal.
