摘　　要：林南仓矿业分公司综采工作面在收尾期间均不同程度的出现过采空区遗煤自燃发火征兆,且自燃发展迅速,对矿井安全生产形成了极大威胁;注氮防灭火工安全有效,是防治煤矿井下自然发火难题的有效手段。本文根据林南仓矿2216工作面收尾期间的条件,研究确定了注氮参数,有效的防治了该工作面收尾期间的自燃发火事故。There are varying degrees of spontaneous combustion in the gob area of Linnancang Mining Branch.The spontaneous combustion developed quickly and form a great threat to the safety of the coal mine prodyction. The nitrogen injection is an effective method to prevente and cure of spontaneous combustion. Based on the conditions of 2216 face,the nitrogen injection parameters were studied. The spontaneous combustion incidents were prevented effectively.
