| 摘 要： | 本文结合某矿采空区的发火现状对标志性气体选择与煤样自燃倾向性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，认定该矿煤层自燃倾向性属于Ⅱ类自燃煤层与Ⅲ类不易自燃煤层。本文的实验研究结果可以用于指导煤矿生产，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: | The choice representative gas and the spontaneous combustion theory were researched combined with fire actuality in a coal mining region. CO,C2H4 , C3 H6 , Calls , C2H4/C2H6 ere were regarded as the representative gas in appropriate conditions, The spontaneous combustion orientation in this coal seam was Ⅱ and Ⅲ dangers. The research result could supervise the production in coal mine. And the degree and incidence of fire in coal mining region could be controlled. The personnel casualty and fiches and coal resource loss were reduced. |
