摘　　要：文章以彬县下沟矿4#煤层为研究背景,利用XK-IV型煤自然发火实验台,实验模拟下沟煤矿采空区浮煤自然发火过程,测算出该煤层的最短自然发火期、临界温度、干裂温度、指标气体产生率、氧化速率和放热强度等自燃特征参数,为下沟煤矿自燃火灾的预测预报及防治提供了依据。Taking the No.4 Seam in Xiagou Mine,Bin County as the study background,a XK-IV experiment rig of the coal spontaneous combustion was applied to have an experiment and simulation on the spontaneous combustion process of the floor coal in goaf.The shortest spontaneous combustion period of the seam,the critical temperature,the dry fracture temperature,the index gas production rate,the oxidation rate,the heat emission strength and the spontaneous combustion characteristic parameters were calculated in order to provide the references to the prediction,prevention and control of the spontaneous combustion disaster occurred in Xiagou Mine.
