| 摘 要： | CO气体作为预报煤炭自燃的指标气体在煤矿中已被广泛使用,但有些矿井回采面上隅角始终存在CO气体,甚至超出矿业安全规定的临界指标,特别是在综采或综放工作面这一现象更明显,尽管采取多种防灭火措施,只能使CO气体涌出量减少而不能消除CO的产生,为了解其原因,在实验室做了不同煤种低温氧化实验,通过实验发现有些煤种在常温氧化条件...

| Abstract: | CO has been popularly used as an index gas to predict spontaneous combustion of coal in coal mines.But in some mines CO gas appears in the upper corner of mining face all the time,and sometime CO gas even exceeds the critical value regulated in Mining Safety Regulations.This phenomenon is much more obvious in fully-mechanized longwall and fully-mechanized longwall with top-coal caving.Although many fire control measures are taken,amount of CO gas can be only decreased,but appearance of CO can not be elimina... |
