【摘要】：为了研究高水充填材料的防灭火特性,促使其更好地应用推广于矿井防灭火领域,针对高水充填材料与传统黄泥材料的阻燃性能开展对比试验研究,分析其阻燃效果及作用机理。通过对比试验发现,高水充填材料对煤自燃氧化过程中的煤自燃氧化升温速率、氧化产生的标志性气体(CO、CO_2、C_2H_4)的生成速率均有一定的抑制作用;同一水灰比条件下,高水充填材料比黄泥材料的抑制煤自燃氧化作用强。结合防灭火工程实践应用表明,高水充填材料的阻燃效果优于黄泥材料,完全可以替代黄泥材料作为矿井防灭火的充填材料。
[Abstract]:In order to study the fire prevention and extinguishing characteristics of high water filling material and promote its better application in the field of mine fire prevention and extinguishing, a comparative experimental study was carried out on the flame retardancy of high water filling material and traditional yellow mud material. The flame-retardant effect and mechanism were analyzed. Through comparative tests, it is found that the high water filling material has certain inhibitory effect on the rate of heating up of coal spontaneous combustion oxidation in the process of coal spontaneous combustion oxidation, and the rate of formation of the iconic gas produced by oxidation, COCO-2 / C _ 2H _ 4), and at the same water-cement ratio, The high water filling material is stronger than the yellow mud material in inhibiting the oxidation of coal spontaneous combustion. Combined with the practical application of fire prevention and extinguishing engineering, it is shown that the flame retardant effect of high water filling material is better than that of yellow mud material, and it can be used as filling material for mine fire prevention and extinguishing completely.
