指标气体预报煤炭自燃在煤矿安全生产中得到广泛的应用,指标气在实验分析过程中,多以自然水分煤样进行的。众所周知,水分对煤自燃有一定的影响,为探讨水分对煤自然发火的影响,首先要进行配制适合实验分析的不同水分煤样,结合18.0%和8.96%水分情况下气体分析,得出水分对煤自然发火指标气体产生了一定的影响,因此指标气体在实际应用时,应结合井下实际具体情况为预防煤自燃早期发火提供更科学的依据。
Indicator gas prediction Coal spontaneous combustion in coal mine safety has been widely used, the indicator gas in the experimental analysis, mostly with natural moisture coal samples. As we all know, water has a certain impact on the spontaneous combustion of coal. In order to investigate the effect of moisture on the spontaneous combustion of coal, we first need to formulate different moisture samples suitable for experimental analysis. Combining the gas analysis of 18.0% and 8.96% moisture, Coal spontaneous combustion index gas has a certain impact, so the index gas in practical applications, should be combined with the actual situation of the actual situation to prevent spontaneous combustion of coal to provide a more scientific basis.
