| 摘 要： | 结合某矿采空区的发火现状对标志性气体选择进行了系统的实验研究,确定了CO,C2H4,C3H6,C3H8,C2H4/C2H6等气体在适当条件下可以作为该矿煤层自然发火的标志性气体。实验结果可以直接指导煤矿生产,从而减少采空区发火的次数和影响范围,降低由此而造成的人员伤亡、财产以及煤炭资源的损失。

| Abstract: | Based on status of coal spontaneous combustion in gob of a colliery,this paper made experimental research on selection of significant gas and proved that under suitable condition,CO,C2H4,C3H6,C3H8,C2H4/C2H6 might be significant gas of coal spontaneous combustion for this colliery.Experimental result might be used to direct coal production so as to reduce spontaneous combustion frequency in gob,influence range and loss of life,property and coal resource. |
