摘　　要：林南仓矿所采各煤层均属于自燃煤层。放顶煤开采采空区遗煤较多,加之漏风通道较多易造成采空区遗煤发生自燃。利用束管系统对1226采空区气体成分进行了测定分析,得出了该工作面采空区煤炭自燃的发火规律,为合理选择预防采空区煤炭自燃的措施提供了科学的理论依据。Every coal seam of Linnancang coal mine belongs to the spontaneous combustion coal seam. The use of top caving mining method left much coal in the gob area. Because there are multi air leakage channels, spontaneous combustion is ofen occurred. In order to strengthen fireproofing management and understand the natural oxidation of the gob area, the beam tube moni- toring and measuring system was used to observe the air contents of 1226 working face. The spontaneous combustion rule in gob area was gotten. It can be used to guide the production of Linnancang coal mine.
