选取硫含量不同的3种相同煤种在相同条件下进行程序升温实验,对CO、CO2、CH4产生率以及耗氧速率等特性参数进行了研究,从而进一步了解硫对煤自燃的影响,为高硫煤层自然发火防治技术提供理论支持。
Three kinds of coal with different sulfur contents were selected to carry out temperature programmed experiments under the same conditions. The characteristics of CO, CO2, CH4 production rate and oxygen consumption rate were studied in order to further understand the effect of sulfur on spontaneous combustion of coal, Sulfur spontaneous combustion prevention and control technology to provide theoretical support.
