【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。
[Abstract]:A variety of measures were taken to prevent and extinguish fire during the period of stoppage and moving of No. 8421 working face in No. 5 Coal Mine of Yangyang Coal Mine. The optimum scheme was selected by comparing the data of temperature and gas component concentration. The results show that the cooling effect of water injection is good, but the temperature is rising rapidly and the working environment will be deteriorated. The injection of glue can control the temperature for a long time, but the cooling effect is not obvious and the economic cost is high. In contrast, the injection of carbon dioxide gas reduces the temperature quickly. The optimum scheme is to keep the temperature stable for a long time after the temperature drops, and not to deteriorate the environment and the economic cost is reasonable.
