西沙河煤矿9#煤层自燃特性实验研究

摘要

In order to grasp the characteristic parameters of coal spontaneous combustion, temperature programmed oxidation experiments of coal samples of 9# coal seam in Xishahe Mine have been carried on. To study coal samples' gaseous products generated with temperature variation in temperature programmed oxidation process. And with the principle of choosing sign gases to determine the sign gases of spontaneous combustion of 9# coal seam in Xishahe Mine. The sign gases provide the basis for the early prediction of spontaneous combustion of coal.%为了确定西沙河煤矿9#煤层自然发火的标志性气体,对其9#煤进行了采样,并对其样品进行了程序升温氧化实验,通过实验检测了9#煤样在程序升温氧化过程中产生的气体随温度上升的变化规律,了解了其自燃特性参数,并与标志性气体优选原则进行比对,从而为煤自燃早期预测预报提供了依据.
