| Abstract: | 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. |
