摘 要:在阳煤五矿8421工作面停采搬家期间采取多种防灭火措施,通过温度和气体组分浓度变化数据的对比选出最优方案。结果表明,注水降温效果好但温度回升较快并且会恶化工作面环境,注胶可以控制温度较长时间稳定但降温效果不明显且经济成本较高,相比之下,注二氧化碳气体降温快,温度下降后能长时间维持稳定,不会恶化环境且经济成本合理,为最优方案。Variety of fire prevention measures were adopted during the stopping mining and moving of 8421 face of Yangmei No.5 coal mine. The optimum scheme was selected by contrasting the data of the change of temperature and gas concentration. The results show that the cooling effect of water injection is good, but the temperature rising is quicker and the working environment will be deteriorated. For colloid injection, the temperature can be controlled for a long time, but the cooling effect is not obvious and the economic cost is high. In contrast, carbon dioxide gas injection cools fast, dropped temperature can maintain stability for a long time, it will not deteriorate the environment and the economic cost is reasonable, so carbon dioxide gas injection is chosen to be the best scheme.
