煤自然发火是一个较为复杂的煤氧复合反应的过程,由于煤本身的煤质特点和其在开采时的周围蓄热情况的复杂性决定了煤自然发火预测的困难性。实验得出的煤本身的自燃特性参数,结合现场观测生产中煤的外部蓄热等情况,采用软件模拟的方法,对煤自然发火预测进行了研究,避免了实验与现场实际结合度低的缺点,预测较为准确,为矿井防治煤层自燃提供了参考。
Spontaneous combustion of coal is a complex process of complex reaction of coal and oxygen. Due to the characteristics of coal itself and the complexity of surrounding thermal storage during mining, it is difficult to predict coal spontaneous combustion. Based on the experimental data of the spontaneous combustion parameters of coal itself and the external heat storage of coal in the field, the software simulation method was used to study the coal spontaneous combustion prediction, which avoided the shortcoming of low actual binding between the experiment and the field , The prediction is more accurate and provides a reference for mine prevention and control of spontaneous combustion of coal seam.
