摘　　要：针对煤炭自燃对矿山开采的威胁问题,对井田煤炭取样实验,分别检测煤温和煤自燃所释放气体的值并获得其相关关系。通过数据拟合与图像分析,得出释放气体的浓度将会极大地影响煤的自燃。基于实验数据与现象,判定在不同温度下煤自燃发生的可能性,从而为煤矿煤自燃预防起到启示作用。Aiming at the threat of coal spontaneous combustion to mining,the coal sampling experiment of mine field was carried out to detect the coal temperature and the gas value released by coal spontaneous combustion and obtain its correlation.Using data simulation and image analysis,it is concluded that the concentration of released gas can greatly affect the spontaneous combustion of coal.Based on the experimental data and phenomena,the possibility of coal spontaneous combustion at different temperatures is determined,so as to play an enlightening role for the prevention of coal spontaneous combustion.
