东欢坨煤矿自然发火标志气体优化选择

Indicator Gas of Spontaneous Combustion Optimized in Donghuantuo Coal Mine

通过实验室实验研究,得出了适合开滦东欢坨煤矿预测预报煤层自然发火的指标气体,由于东欢坨煤矿煤层中赋存有CO,因此,在利用CO标志气体时,必须进行修正,利用CO浓度差值法和ICO来消除环境因素和风量的影响,以便更好的预测预报煤炭自然发火和分析火区燃烧状况,对同类矿山的防火工作也有一定的指导意义。

In this paper, indicator gas of spontaneous combustion in donghuantuo coal mine were found by experiment. It must be amended of CO indicator gas because in the seam has CO. We can use the difference of CO and ICO to eliminate the effect of environment and the air, and to forecast and analyze the spontaneous combustion. It can help to prevent the fire in the congener coal mine.
