摘要
利用大型煤低温自然发火实验台,对枣泉矿2#煤层煤样自燃特性参数进行了测定,确定了煤的最短自然发火期、临界温度、干裂温度、指标气体产生率、氧化放热强度和自燃极限参数,为枣泉矿自燃火灾的预测预报及防治提供了参考依据。
A large scale low temperature coal spontaneous combustion test unit was applied to measure the spontaneous combustion feature parameters of the coal samples from No.2 seam in Zaoquan Mine.The shortest spontaneous combustion period,the critical temperature,the dry cracking temperature,the index gas production rate,the oxidization heat releasing strength and the spontaneous limit parameters of the coal were determined,which could provide the references bases to predict and prevent the spontaneous combustion disasters in Zaoquan Mine.
